Jeff and Freddy did a great job installing our new furnace and air conditioner. They had great attention to detail making sure everything was sealed up appropriately. They showed us how to use the thermostat and change the filters. read more

If you are considering using Environmental Heating and Air Solutions (EHA Solutions)--even through the Costco program--please read this first and look elsewhere. We paid over $36,000 for a flagship Lennox Signature Series heat pump system, and the entire experience has been an absolute nightmare of safety violations, incompetence, and broken contracts. Here are the documented facts of our installation: 1. Safety Hazards & Property Damage During the install, the crew disconnected our gas line during unistall of our gas furnace without shutting off the main valve, causing gas to leak into our home on two separate occasions. They also haphazardly stored heavy, explosive oxygen tanks and oil inside our plastic deck box, permanently deforming and damaging our property and creating fire hazard. 2. Immediate System Failures & "Vaporware" Fixes Within the first 24 hours, the system suffered critical electrical shutdowns, throwing "Inverter DC Peak Faults" and shutting off our heat every morning. The system's own diagnostic panel showed impossible voltage spikes (550V) and 0.0 subcooling (wrong refrigerant readings). Instead of fixing it, EHA technicians repeatedly dismissed these hard mechanical failures as mere "display glitches." We later found out from Lennox engineering that the inverter error is a known defect with no current fix other than a theoretical future software update. 3. Unauthorized Modifications & Broken Zoning EHA breached our contract. They certified our existing ductwork as "adequate" in writing, but then performed unapproved structural modifications to our ducts without a signed Change Order. As a result, they completely broke our zoning system. 4. Severe Compressor Vibration and Unprofessionalism They mounted our variable-capacity outdoor unit on a field-fabricated, angle-iron stand, creating a severe harmonic vibration that wakes us up in the middle of the night. When they came back to "fix" it, they wedged isolation pads under the connection brackets without our permission or awareness, making the noise even worse. To top it off, during an onsite visit, the Lennox field technician was confrontational and actually told us directly that he would never replace his own gas furnace with a heat pump--a stunning admission about the very product they just sold us. We have officially demanded a full removal of the equipment and a full refund through Costco, and we are escalating this to the California Contractors State License Board (CSLB). Do not trust this company with your home, your safety, or your money. read more

Environmental heating and air solutions upgraded our HVAC and we are very happy with their services. Paul Marceau did a great job explaining to us what is needed and provided various cost and equipment options that we can choose to fit our needs. The installation took 4 days, started and completed on time. Richard was professional and knowledgeable. We had a major issue that can only be fixed with additional technical support, and Richard followed thru to make sure the tasks are satisfactorily completed. Thank you for the great service. Highly recommended! read more

We had issues with our furnace going out. I contacted EHA solutions requesting a diagnostic asap. They were able to accommodate a same day visit later in the afternoon. Martin Palacios was the technician who came to my residence. Martin arrived right on time. He was very knowledgeable, patient, and explained everything he was doing every step of the way. Martin diagnosed the issue promptly after ruling out different possibilities that could have been causing the issue with our furnace. He made the necessary repairs and our furnace is up and running without any issues. We're very grateful the issue was promptly resolved and even more pleased with Martin's work. EHA is lucky to have him on their team, 5 star service for sure. read more

Martin from EHA came over today for the routine A/C maintenance. He arrived on-time and has a very professional attitude. He provided a lot of maintenance advice and walked me through all the work that preformed. He is truly passionate about helping customers getting the best service possible, and EHA should be proud of having someone like Martin to represent the company! read more

Freddy was a great tech. He was very polite, knowledgeable, and professional. He checked our Lennox system and helped us diagnosed possible causes of the room being not heated so well and recommended a way to fix it at relatively cheaper cost for us. He also pointed out some potential overheating hazards in our attic. I will definitely recommend Freddy for any AC or heating problems. read more

After several disappointing and costly experiences with other HVAC companies, a friend recommended Environmental Heating & Air Solutions (EHA Solutions). Impressed by their work in replacing the HVAC Systems for both his business and home, my friend's endorsement gave me confidence to reach out. EHA Solutions has earned a spot as a Preferred Installer for Costco, so I contacted Costco and they scheduled EHA Solutions for a complimentary in-home consultation with me to discuss my project. The technician took time to understand my needs, thoroughly reviewed my system, and clearly explained their recommendations. Their quote was competitive with the others I received, but the professionalism and clarity of their presentation set them apart. The installation process was smooth--every team member was polite, efficient, and knowledgeable. I am extremely satisfied with my new HVAC system and have already recommended EHA Solutions to others considering replacing their HVAC Systems. read more

Today I had my annual heating inspection. Jon Cardiasmenos was great. He talks meaningfully about what he was planning on doing and then what he did, with pictures to show. I feel confident that my relatively new Lennox system (installed by Environmental Heating, via Costco) is in good hands. Environmental now has an office in Benicia, closer to me, in addition to their original Roseville office. Perhaps Jon will be returning for my annual A/C check up. read more

I cannot tell you how terrible of an experience we had. The first time that our AC broke it was during a heatwave. We called multiple times only to get routed to a answering service. When we left a message we did not get any response back for 4 days. It took constant calling to finally get routed to the main office. Finally, when we got rid of to the main office we were able to get an appointment. The technician came out, looked at our unit and said nothing was wrong and restarted the system. A few days later the AC went out again and we had to go through the exact same process. Calling multiple times and only getting the answering service instead of the actual office. They came out and still could not find anything wrong with the unit. I can't stress enough how terrible this was. I highly recommend going with somebody else for your heating and cooling needs. read more

I was connected to this company through Costco's Lennox heat pump program. I made an appointment several weeks in advance. I received several text messages from the company leading up to the appointment. I confirmed with the company that I still wanted the appointment in response to their texts, including one the day before. I took off time from work and arranged my schedule around their in home visit. Then 30 min before my visit they called me to tell me they were refusing to come to my house. This was completely unprofessional. read more

We spent 30k less than a year ago on a new Lennox Air Conditioner. we also signed up for their month maintenance plan that supposedly gives us priority service . The Circuit breaker continually pops and we have placed several calls in to them for repair. We initially were told someone would get back to us and now our calls for service are just ghosted. Good at selling , terrible for service. read more

Jon Cardiasmenos did our semiannual inspection and was very friendly, funny, and thorough. He explained everything he did and why, with a strong emphasis on safety. I strongly recommend him and welcome him back for future inspections. read more

I live in the Berkeley Hills and was a commercial contractor for 30 years. My expectations are high, but EHA met and exceeded them. Mathew C. is extremely professional and did a great job on the initial site visit and estimate. The install crew, led by Kevinn, was extremely courteous, professional, and meticulous. I had a couple minor change requests to improve the install aesthetics and without hesitation, Kevinn made the changes to ensure my satisfaction. I would have been so lucky to have installers like Kevinn, Jesus and Raul representing my company. Well done. read more

Jon Cardiasmenos was an excellent tech. I would definitely recommend him for your service needs. he's polite and very thorough. I have been using this company for 8 years and have never had problems and they don't try and pressure you into buying unwanted products. read more

Shannon was EXCELLENT! He called to find out if he could come earlier than scheduled which worked out well for me. When he arrived he was pleasant and asked if I would like him to wear protective booties to cover his shoes. After attentively listening to me he explained everything I needed to know about his services and the costs involved. He did not try to pressure me into any services and was honest, clear and straight forward in his interaction with me. I recommend Shannon and company highly and with enthusiasm. Tom Y read more

Douglas and this team did a very professional job in installation of A/C and Heating system. Kept me informed of all the progress during the insulation process. Explained the basics of the system, set up and necessary instructions for maintenance. read more

About a year and a half ago, I contracted EHAS to replace my gas furnace and air conditioner through Costco. The installation went, okay, except that they removed and destroyed my Honeywell Electrostatic Air cleaner, and the first air conditioner unit they installed failed immediately. A couple of month later, they call me to join their service club, which would cover 4 inspections a year to keep the warranty in force. I joined and a couple of weeks later a technician came out to do the first inspection, about a year after installation. At the end of the inspection, he het me with a $2,500 estimate for repairs! He said that a fan inside had dust on it and would have to be removed an cleaned with a $2500 cost. He also tried to upsell me a new filtration system that the installers previously said there was no room to install, or I would have bought it then to replace the Honeywell. He claimed I didn't change the filters enough. My wife has respiratory issues, and insists that I change the filters regularly. I installed five filters in the year. He claimed that the filter he just changed was clogged and had deformed to let unfiltered air through. The filter holder they installed prevents any deflection or deformation of the filter, which was not clogged in my estimation. It was only 6 weeks old. I wrote a complaint letter to the general manager, but he ghosted me. I complained to Costco. In less than a day, someone from Costco got back to me, and got someone from EVAH to call me. That call did not go well. The customer service rep right off the bat said that the $2500 quote was in error. The real cost would be $1,250. That was still way too much to pay to have a fan cleaned on a year-old furnace which had its filter changed frequently, and I said so. The customer service representative again accused me of not changing the filter often enough, which I denied, and told him of my filter changing regimen. He again accused me of lying about changing the filter. We went back and forth uselessly and repetitively for a while, when I stated my bottom line: the repair needed to be done free-of-charge. After a bit more go-round, he agreed. Okay, then. We're done. But they've never come out to fix the problem they claim is going to void my warranty if unfixed. So, time goes by. I'm waiting for them to come out for my summer inspection, as our maintenance contract requires and I have pre-paid for. Crickets. So I called them today to find out what's up. The customer service person, a different one, says she can't figure out why they haven't called me to set one up by now, but they're booked until late July. The furnace and air conditioning equipment they installed works great. I went with the really high efficiency model, which was an upgrade from what they suggested we install. But they're customer service sucks, and their business practice is suspicious. read more

Two and a half weeks later and 3+ techs have come out and I still have a system that is partially broken. Turns out that even though EHAS advertises emergency services, they don't really have on-calls on Sundays, that's the reason why they didn't come out. After many calls and frustration, I decided to troubleshoot, I ended up cutting power to both the condenser and furnace/blower and that brought it back up. When the tech came out two days later after it initially went out he said there is nothing they can do unless the problem is there, but they can't be here when the problem is there, so it's a lose lose situation for the consumer. This weekend on 7/16 my system went down again, on a Sunday during 113 degree weather. I had to restart it again because they couldn't come out. Whereas the system came back up, the thermostat upstairs got all screwed up. Temperatures are not correctly reading. There is also little or no air blowing on my upstairs zone. Another tech came out and said it was a configuration issue (which maybe the thermostat was but not the air flow). He changed some zoning configuration and for the air flow increased the CFM, and of course it made a bit of a difference. I asked the tech two questions: 1. Do you think this is an issue with a damper not working correctly? 2. Would the system tell you if it was a damper issue? To both he said no, he was pretty sure it was a configuration issue and didn't bother to check the attic unit/dampers. Well, they left the system turned off, and when it came back on, again no airflow upstairs. In my frustration I decided to troubleshoot it myself, again. I went upstairs, and sure enough the damper is either not opening or gets stuck between 20% and 30%. The tech recommended tapping on the damper, which helped open up the damper, but when it closes and opens back up it gets stuck again. This was Monday 7/17. Here we are on Thursday 7/20 and after multiple calls and promises that we are in their schedule as "high priority" no one has come out nor are we receiving any type of ETA. We're expecting another heat wave 100+ degrees starting tomorrow, and we're still with a NEW system that's not working. read more

My HAVC is two zoning system and has been using for 20+ year. One of the zoning is also not working. Solar and water softener was install from Coscto. The 2 systems installed a seamlessly. I deceded to replace my HAVC with Costco also but it is a very unhappy experience. 1. I have to take off half day on 7 days. Day#1. EHAS come out to do installation which is normally When they finished, they told me I can turn on the system. So I start turning on the system to see if it works properly. I set to 71 degree on the thermostatic but the temperature on the downstaire never reach to 71. The thermostatic stayed at about 75 degree during hot day (100 degree outside. The next day I set the to 68 degree but it stay in 74 only. So I start calling them. They told me to wait for Arcon to come out the inspect. The thermostatic on the 2nd floor can not turn off and on the system. So if I need to turn off or on system, I have to go down to the 1st floor to do. The sale people did not let me know when they come to explain to me about the system. My old system can turn on or off on the 2nd floor thermostatic. Day#2. Arcon come out to inspect if EHAS install correctly When they come out, Arcon found one of the duct did not connect to HAVC completely. That means the air is blowing out to the attic. It's amazing that the installer did spot it when they complete the work. The HAVC is located in attic. It took 2 weeks to schedule the appointment. Day#3. EHAS sent people out and fixed it but the temperature on the 1 floor still not get close to temperature that I set. Then I started to call them again. The sent out another guy to come out to talk to me. Again they told me to wait for Arch to recheck again to see if there is any more issue. If the Arcon find any issue. Replece a portion of duct to 14" could help but that is my expense. It took 2 weeks to schedule the appointment. Day#4 Arcon come out agine and inspect. Arcon said ok. It took 2 weeks to schedule the appointment. Day#5 I scheduled City inspector to inspect the HAVC. The inspector come out but I have to set the ladder for him to get up to the attic to inspector. Day#6 The city inspector complain something is not corrected. He wrote the problem on the permit. Day#7 Schedule again with EHAS to fix whatever it need. I told EHAS to have a experience install to call me about 14" duct replace but they never call me. It took 1 weeks to schedule the appointment. Day#8 City inspector passed finally and signed off. The sale person not only did not let me know anything about the system. She did not tell me about the Arcon or city inspector. I expect EHAS should be here when the city inspector inspect and I dont have to deal with the City inspector. That should be contractor work. They install the "return" unprofessionly. I will put negative or zero star if i can . read more

My HVAC system was 23 years old and needed to be upgraded. I decided to use Costco and they connected me with EHA solutions. Overall the communication between sales and installation crew was very good. Install took one full day and the crew was very friendly and professional. The system was then pressure tested and passed very easily. I know that it wasn't the cheapest but having the peace of mind that Costco does business with EHA solutions assured me of my decision. read more

We recently replaced our HVAC with a Lennox heat pump, furnace and AC system. We contracted EHAS through Costco. Every step from sales to installation to follow-up service was professionally handled by Kevin (sales), Kevin V and crew (install) and Jon (follow-up). The system ran quietly and smoothly from the start, but some follow-up was needed to fix an error code that showed up on the thermostat. Jon came out first thing on Monday morning and quickly fixed the issue. Having the error code wasn't ideal, but having it fixed quickly and efficiently earned EHAS our five-star rating. read more

We went thru Costco for the replacement of our current heating/ac unit, and used this company. Kevin came out initially to check out the current system and the duct works, sat down and explained to me about the system they offered. They sent me the quote via email. Paula called a week later and followed up with us. With the Costco discount and rebates, this was the most affordable price. The came to install and take away the old unit. Everything was fine in one day, and came the next day to upgrade the power panel. It passed all inspections, we highly recommend them! read more

It's with pleasure I share a 5 Star review today. Alexa, from EHS, just completed a routine maintenance call on our HVAC system. Though all techs having performed maintenance calls since equipment installation have appeared to be experienced, efficient and knowledgeable, Alexa was outstanding at all of the above, and coupled with great customer satisfaction skills, there was no doubt she was in tune to each and every detail, and committed to following maintenance protocol to its finest. Alexa is a superb representative of EHS, and I hope she's available to schedule and perform our calls in the future. Thank you EHS & Alexa!! read more

I had an estimate done through the service from Costco. I signed the work contract but later the same day I sent the cancelation notice. I got email confirmation of the cancelation. Fast forward 2 weeks...EHA sent a work complete notice the the finance company. Even though I notified the finance company I canceled the contract they still paid EHA. I've spent the last week trying to fix this major screw up. My credit has tanked down. I've asked EHA to call multiple times to get a text message. After that, crickets. They've caused a total mess that is taking hours of my time to rectify. read more
