Working with Sun Air was one of the best decisions we've made for our home. What started as a fairly ambitious project installing solar panels, battery storage, heat pump HVAC systems, hybrid heat pump water heater, upgrading our electrical service, and adding EV chargers could have easily become overwhelming. Instead, the entire process felt organized, transparent, and expertly managed from start to finish. From the very first meeting, it was clear we were dealing with a team that truly understands whole home electrification, not just individual systems in isolation. They took the time to evaluate our home's current energy usage, electrical panel capacity, and long term goals. They then designed an integrated solutions where everything works together efficiently and effectively. They explained the pros and cons of different equipment options without pushing unnecessary upgrades, which made it easy to trust their recommendations. The solar and battery installation was handled seamlessly. The crew was professional, punctual, and clearly experienced. They completed the work with attention to detail, clean wiring, and thoughtful placement of equipment. This ground mount solar system was comprised of 46 Maxeon 475 watt solar panels paired with Enphase micro inverters totaling to a 21.9kwh system which is located at the bottom of our property perfectly positioned for maximum sun exposure. The battery system integration was especially impressive, and they walked us through how backup power works in real world scenarios, not just in theory. They installed 6 FranklinWH 15kWh aPower 2 Batteries totaling 90kwhs of battery storage. The HVAC upgrade was two Carrier Infinity 23 series heat pump systems was another standout. They carefully assessed airflow, ducting, and insulation before installation, which made a noticeable difference in performance. Both Hvac systems and ductwork are sealed and balanced, so there is no air loss. The systems run quietly, maintains consistent even temperatures from room to room, and is far more efficient than our previous setups. As for air quality we chose to go with the Lennox Pure Air purifier Merv 16 filter with a UV light that helps fight mold, viruses, bacteria, pollen, dust, animal dandruff, and smoke from forest fires. We felt this was something we were in great need of, because of the horses, animals, and vegetation kicking up all the dust on our farm. All in all it was the best option out of all the air purifiers and we can tell a large difference with our home's air quality. The same level of care went into the Rheem ProTerra heat pump water heater installation and it's operating efficiently. It was installed in a way that minimizes noise and maximizes space. They ran a sheetmetal duct from the attic to pull hot air through the unit, so it runs more efficiently, and uses less electricity. The electrical service upgrade could have been disruptive, but they handled it with precision and clear communication. They coordinated inspections, permits, and utility interactions without us having to chase anything down. They upgraded two sub panels to 100 amps each from 50 amps and the main to 400 amps from 100 amps. Everything is labeled clearly, and the panel layouts are clean and are future proofed (ready for the new pool and hot tub). I feel relieved to have the old Zinsco fire hazard panels replaced. Adding three 50 amp Charge Point EV chargers was the final piece, and again, they thought ahead, and positioned the chargers for convenience while ensuring the electrical load was balanced with the rest of the electrical system. Charging is fast, reliable, and integrated smoothly into our overall energy setup. What really sets this contractor apart is their communication and project management. Peter, Adrian, Jake, Wyatt, and the other guys were a pleasure to be around. We always knew what was happening next, timelines were realistic, and any questions we had were answered thoroughly. There were no surprises, no shortcuts, no pressure, just consistent high quality work. Overall, this was a very large complex multi system upgrade, and they handled it with a level of professionalism, and care. This expertise is hard to find. Our home is now more efficient, more comfortable, and better prepared for the future. I would absolutely recommend them to anyone considering solar, home battery storage, whole home electrification, Hvac services, or any other major energy upgrades. read more

Were about to leave the country for 2 weeks when our propane fired furnace under the house went south. I had just enough firewood to cover us for a few days after we returned, but after that we had no heat, and the morning temps were hitting 36 F in our area (Santa Cruz mountains). Based on a neighbor's recommendation I contacted SunAir to see if, short term, they could get the old furnace running, and after that advise me as to replacing the 40 year old furnace with a new one. I contacted them late on Friday and they responded that they could stop by on Monday. When Peter showed up I went under the house with him to troubleshoot the furnace. To make a long story short we both agreed that trying to get the 40+ year old furnace running (dead control board) would be a waste of time. Also the ducting (mostly over 40 years old) was in pretty bad shape and installed in a sloppy manner. I got a quote from Peter for replacing just the furnace and another quote for a complete furnace and ductwork replacement. I decided to rebuild the whole system. Peter quoted 3 days to complete the job and was able to start a few days after that. Unfortunately, in the middle of the job we had a day of rain that ended up flooding under the house where the furnace was located. It turned their work area into a mucky mess, but they kept going and finished the job on time. I'm fairly certain that many other contractors, confronted with the same circumstances, would have halted the work and left us with no heat for many more days. Kudos to Peter and his crew for putting up with the terrible working conditions and getting the job done on time as promised. read more

We have worked with Peter and Sun Air a number of times (moving furnace and new tank less water heater to our attic, re-doing all of our ducting, installing a small split AC unit in our second story) and they have always gone above and beyond. Our most recent job with Peter and his crew was a complete re-do of our two bathrooms and kitchen simultaneously. We moved out during this work (& out of the area) and had no concerns that the job would not be done on time and up to our high standards. Peter dealt with all issues that arose (items which took longer as a result of Covid, confusion on timing from subcontractors we hired) and our additions and worked hard to complete the job in the time frame he promised us. He is always neat and attentive to our home. Additionally, he brought some things to our attention that he thought would be better done in another way-and every time he was right! He made what could have been such a stressful process so easy for us. We are thrilled with how it all turned out-the subcontractors he use have the same work ethic and are perfectionists just as he is. He got the last details finished once we moved back in done in a timely manner as well (with contractors we have worked with in the past this part was like pulling teeth-took a lot of work to get them back to finish-not so with Peter-he had each trade scheduled to come by in take care of the final touch ups). We cannot recommend him and his crew strongly enough. If you hire Peter for a job, you will never be disappointed! We know we will use him again in the future. read more

Woke up in the middle of the night to find out that my furnace wasn't working at all, so I came across Yelp online, and found SunAir. We emailed the company and Jenelle responded rather quickly with an appointment that accommodated our busy schedule. Peter came and assessed the situation. Come to find out our furnace was over 24 years old and the heat exchanger had hair line cracks (he showed us with his telescopic camera), so he recommended a new furnace. We decided that maybe an upgrade on the whole hvac system might be the better way to go (since the whole system was 24 years old and the ducts were leaking air), so we got three quotes from other Heating & Air Conditioning companies, and SunAir was right there in the middle with the price. The other companies agreed with the furnace needing to be replaced as well (which made us more comfortable with SunAir), so we decided to go with them. The whole overhaul took about 7 days and the crew were very responsive to any questions that we had. They were on time and very friendly everyday during the process of the heating & air conditioning installation. The work was finished in the time frame and the quality install was definitely felt through out our home. We have airflow in areas that we didn't before (wife is super happy). If your looking for an Hvac company that knows whats up and has fair prices give Peter a call. read more

We recently used SunAir for a furnace replacement and air conditioning installation with new ductwork, since our heating system was original from the 1980's. Peter and staff were professional, quick and did an excellent job! I was impressed with the fact that the owner was on site the whole time for the new Hvac installation from beginning to end. It made me more comfortable. Since we were so impressed with with SunAir we decided to use them for our solar installation as well. Peter did a whole house energy audit and told us where improvements were needed to help bring down energy demands. They installed a 6.45 kWh grid tie in solar system and did l.e.d. lightning upgrades through the our home. It feels good to be part of the green movement. We have used multiple contractors from many different trades over 40 years and found that most are irresponsible and unreliable, but with this company it was painless, and exciting. They gave us project updates everyday and kept us in the loop at every angle. They even called twice after the completion to check on us to make sure everything is working properly and to make sure we are fully satisfied ( I've never had a contractor do that, it's a rareity, they actually care about their customers). If you need an Hvac contractor, or an Electrical contractor we highly recommend SunAir. read more

Sun Air recently installed a new HVAC system. Both the AC install and furnace installation went smooth with no hiccups. The workmanship and professionalism was excellent. Our new Bryant Evolution high efficiency system runs perfectly and quietly. In addition, he installed a Honeywell electronic air purifier, and attic fan to enhance our air quality, and energy load. They also installed a new fan light combo exhaust fan for our master bedroom, new water heater, and new lighting in our garage. This Heating & Air Conditioning company goes one step beyond in making sure his customers receive a professional job, done in a timely fashion, and with the least amount of interruption to your daily life. Price was competitive and they were in the middle of the three quotes we received. We have been very pleased and would recommend this company to friends and family. Peter and his crew were wonderful and have an extensive background in the construction industry. He carries three licenses with the contractor state license board and they make it look easy when it's not. Thank you Peter, Pilar, and Jim. We are comfortable now and we appreciate all your hard work. Oh did I mention...they did all this in 105 degree temps. Keep up the can do attitude. read more

When I think of hiring anyone, I often think the adage that "You get what you pay for." All my ducting was in shambles underneath my house. I got 3 quote and Sun Air was the highest quote of the bunch about 15% higher than the next quote. I called Peter and told him he was the highest quote and at first he was a little irritated but he really explained to me what he was going to do and his quote included some things that no one even discussed with me. Well he did the job. On time, very clean, very professional and overall a superb job. 2 things happened on the job. One the original contractor did not install my furnace correctly and as a result thereof there was a gap which let air in the house. And as he explained the problem, I was kind of expecting that he was going to charge me, but he just did the work. Also, I needed an air vent duct from my dryer to the outside. He took the duct through the roof and did a great job. Once again, an unforeseen problem but he just did the work at no additional job. I would wholeheartedly recommend Peter and Sun Air. He not only comports himself to the highest level of workmanship. He conduct himself with integrity-a personal characteristic which is often times in short supply. Great job! read more

Peter and Adrian at SunAir specialize in excellent Heating and Air Conditioning installation and ductwork, and you will not find a better local company if you want quality workmanship and service. Our very old furnace went out (cracked) in early February this year while it was still very cold. When we thought it could just be fixed, we called many companies, and Peter was the only one who answered the phone and came by right away to see if he could fix it. When we found out it was not repairable, we checked Peter's reviews, and they were really excellent. Peter and Adrian's work was exactly what you hope for. They worked hard, were extremely knowledgable, were very conscientious, and were a pleasure to work with. Their ductwork was particularly impressive. Peter was also very careful when he had to put the cold air return in the hallway because he knew I had just painted it, and didn't want to have to redo it. His attention to detail was also excellent, and he seems very well regarded by not only his customers but by other professionals in the business. He are extremely happy with our new heater and air conditioner, and we plan to hire him again soon to replace our old water heater. read more

It was 101 degrees out and my air conditioner decided to quit working, so I was is need of a mechanical contractor. I went over to my neighbor Steve's house who just had his heating and air conditioning replaced by SunAir, so I asked him how his system was running, and he seemed to be extremely pleased with Peter's company. Needlessly to say I retrieved the phone number from him for SunAir since he was so happy with Pete's work. Peter came on time and quickly diagnosed the issue. The compressor was blown which really didn't surprise me, because we had that ac unit for 23 years. We had him replace our outdoor unit and evaporator coil in order to have our cooling system work properly. We were very pleased with his professionalism and his work ethic. He is friendly and knows his proffesion. The ac repair took about 6 hours and we were cool again. These guys are like the doctors of Hvac and we would refer them like Steve did to us. Thank you for your hard work to keep us comfortable. I forgot mention everyone else was booked out for 2 to 3 days, but he took our age into consideration and did the install on a Saturday. Unbelievable customer service! read more

I don't even know where to start, because the project was so large. Peter Cross who is the owner of Sun Air came out and gave us a quote for a whole home conversion from all gas appliances to electric which we have been meaning to do for quite sometime. After careful thought, since the project was such a large investment, we chose to move forward with it. It included a full solar installation with whole home back up batteries. A new main panel upgrade with one sub-panel. A heat pump water heater installation with a water softener and whole house water filter. In addition, we added a new central Hvac heat pump installation with all new ductwork for the main house and a four zone mini split heat pump installation for the pool house, the four zones were necessary for the pool house as it has vaulted ceilings. Additionally, two car chargers with an additional circuit to convert our gas range to electric. We are now a gas free house with no electric bill. I will start off by saying Peter, Adrian, and Jacob were so friendly and extremely knowledgeable. They worked hard on this project and we are very pleased with the outcome. read more

Just - Wow! This company sets the gold standard for excellence. They went above and beyond for our family today and we are beyond grateful. Our heater stopped working. In December. We've had a major storm passing over us and it's been cold, rainy and overall pretty miserable. Adding to that we have school age children in the house. My friend had recently had work done by SUN AIR and gave us Peters number and told us to reach out. We messaged SUN AIR. Response time was fast. We were communicated with in the most professional yet compassionate way. They really cared. We were squeezed in and Peter was able to work around our schedules and constantly communicated with us about timing. He is a genuinely kind person and more importantly knows his stuff. He had us up and running within the hour! And the major crisis that I had invented in my head and literally lost sleep over turned out to be an extremely affordable fix. If you are looking for a professional, fast, competitively priced company who also cares about their customers you've found them. I can't recommend SUN AIR enough. We'll be customers for life. read more

I called SunAir from Aptos, Ca to do a furnace repair when my furnace quit working. Peter informed us that our furnace was 47 years old and it would be better to think about a furnace replacement instead of a repair, so after some thinking we decided to go with the 2 stage high efficiency 96.6% furnace replacement. Peter said it would be a better investment and energy savings, so we moved forward with the installation process. They were very respectful of the surroundings in and out of our house. The crew was always on time and happy to work. It was a pleasure having them. One month later we received our energy bill and boy was he right, our bill dropped about $85 a month for the heating season. We didn't realize how poor our Hvac system was working until the new furnace was installed. We have been let down by other companies in Santa Cruz, Ca area before, so well be recommending their heating and air conditioning service to our family and friends. Thank you for your good craftsmanship along with your fair price SunAir Heating, Air Conditioning, Electrical, & Solar. read more

Peter, owner of SunAir, literally saved my house which at the time had a rodent infestation in the ducts under the house and they were coming into the house!! The ducting was replaced and brought up to code and the rodent's entry point behind the dryer was then replaced with sheet metal making further entry impossible. So my house was safe again and peace was finally restored. I found Peter through a neighbor and Peter is one of the angels in my life. He and his crew, one being his father-in-law corrected all of the existing deficiencies of my out of code system under my house and on a very hot miserable day. What a nasty JOB! Good humor and courtesy was the mark of the day. Additionally, they later replaced both of my furnaces, A/Cs, and ductwork. All was done excellently by extraordinarily pleasant people and ones that give you great confidence in them and their work. You can hire Peter and relax as the job will be done correctly. I will be talking with SunAir soon about solar for my house. I would not hire any one but this company. read more

We have used Sun Air for over 20 years on several stores in the Bay Area for our heating and air conditioning installations, repairs, services, and maintenances. We had them install multiple commercial/residential hvac units for our restaurants and other off site projects. We built a strong relationship with them and have had them working on our personal homes as well. If you are looking for an Hvac Contractor that has mastered their skillset...Sun Air is the place. The owner Peter walked us through multiple avenues/options we could take and tackled our issues at hand. He makes the process easy and efficient. There is no pushing a sale and we could count on them every time. Shows up on time everyday and the crew cleans up after themselves as well. There is a difference with this outfit compared to the ones we used prior. Peter is a specialist, perfectionist, professional, problem solver, and is a positive solution seeker. We continue to use Sun Air till this day and continuously refer them to any of our partners, friends, and family. read more

Sun Air recently installed a new heat pump, fan coil, and thermostat in our Felton home. They were simply GREAT in every aspect of the job. Sun Air owner Peter and his assistant Adrian came initially to examine our existing (27-year-old) unit for possible repair, and immediately noticed some faulty wiring (which a previous repair crew had completely missed), but also that our heat pump component was no longer functional. So we discussed options for a new unit, which Peter presented and explained carefully. The cost quoted was very fair. Installation required a few days but went very smoothly. The Sun Air crew -- Peter, assisted by Adrian, Wyatt, and Jacob -- were always punctual, very courteous, considerate, friendly, clean, and professional. All of Peter's email communication was clear, timely, and comprehensive. We're thrilled with our new heat pump and enthusiastically recommend Sun Air for anyone seeking repair or replacement of heating, cooling, or water-heating equipment. Their work is first-rate! read more

Are you looking to be treated with respect and with someone very knowledgeable in HVAC repair and installation, then this firm stands up every time and gets it done right! Upon meeting Peter, it took all of 5 minutes for me to hear that he truly cared. I have had nothing but issues with service related firms and their unreliable workmanship that I am very pleased to see he gets 5 stars from everyone. I'd be hard pressed to see that ever change as that is the kind of work ethic Peter puts into his work. We've used Peter now multiple times the past 5 years or better and his willingness to troubleshoot the problem efficiently and then repair the problem the first time will always have me calling him for all of my HVAC needs. If you want it done right and at a reasonable price, then you will find Peter is hands down the man for the job. Word of mouth is everything in my book and if you call on him, you will see all of what I mentioned inside 30 minutes of having met him that he is the real deal!! read more

We were remodeling our house and noticed our ductwork was crushed and broken in several areas. Many spots didn't have any insulation as well so our general contractor recommended SunAir. We decided to give them a shout and Peter (the owner) responded quickly. We knew the heating and air conditioning system and ducts were installed when the house was built so it was time to be replaced. Peter and his crew came and demoed everything. They installed a new high efficiency furnace and air conditioning with all new R-6 ductwork. They were always on time, very cordial, and a pleasure to work with. Peter and his team always made my family and I feel comfortable and safe. SunAir passed city inspection first try without any issues. We would definitely use them again. Our HVAC system runs extremely well and very quiet, we are more than pleased with the installation. Thank so you much Peter, Jim, and Pilar for your hard work and for being GREAT people to work with ! We appreciate all your services. read more

Sun Air Co. the owner Peter Cross is fantastic! They are able to do everything quickly, professional and does fantastic work. There is no other general contractor that I would use. Very trust worthy. I would highly recommend Sun Air Co. We were looking for an all in one contractor that has the ability to take care of any trades that we needed done and they have the skills that are necessary to do just that. We had Sun Air do a furnace replacement with air conditioning installation, duct work replacement, water heater installation, electrical lighting, plug and switch replacement, and copper repiping all through our home which is located on the San Jose / Los Gatos border. Extremely clean work, professional crew, and great communication skills with the process and planning. All in all we will are 100% satisfied with their timely completion and remarkable work. Anybody looking for an Hvac, Solar, Electrical, Building contractor I would definitely go with this company. Amy San Jose Ca read more

Sun Air employee PaulReal53@ saved the day for me like no other heating and cooling company did for me this week. I made 15 phone calls to have my air conditioner looked at and was told because of the heat weave I could not be serviced this week at all. When I saw the Sun Air truck in my neighborhood I took a chance to see if they could take care of my air needs: Paul said if one of his appointments fell through or if at the end of the day he had time he would look at my system. As it turned out, it was like 7:30 pm Paul called and indicated that he was heading to my home to look at my air conditioner. I figured he was done for the day after 7 pm. Paul knew what he was doing when it came to HVAC and electrical works. I want to thank him much for his prompt assistance in getting my air conditioner up and running so timely.. Sun Air will be the company I call for future air conditioner service needs. Thanks Paul, You the man Paul, you the Sun Air man. Brian Sacramento CA read more
