I requested a quote to install a NEMA 14-50 outlet for charging my Tesla in my new house in SF. When it comes to services I highly value quick responses, punctual visits, and price transparency. Chris provided all this by responding within an hour of my request, communicating quickly via text, and coming the next day to provide a quote. I got a couple others and his was quite competitive and I appreciate how communicative he was. Day of the install, he and his team were right on time and did the job very quickly and with high quality, it looks great and works perfectly! He also answered some of my general questions about my new place's electric panels, which was great. Will be using again for future projects! read more

Within a little over a month, stupid wall heater went in the trash! Took two weeks to arrive and was a total waste of money read more

I had reached out to Nasa for them to install a Gen 3 Tesla Wall Charger. This was my first time buying a Tesla and I needed a home charging solution ASAP so I needed quick service. Chris responded to my quote request within minutes and came over to do an estimate the next day. Chris was really professional and helped answer my countless questions. They gave the best pricing out of all of the quotes I received from other parties. Rather being sneaky about price like the other companies I had talked to, Chris was very upfront and transparent. When the day came around, Chris and his team were actually an hour early. They finished right on time and the job was impeccable. Really pleased that I was able to meet Chris and am grateful for their service! Will hit them up when I need an air con system. read more

This should be -5 stars I hired Nasa Heating in 2019 to replace my water heater and a 70 year old furnace. They were the cheapest in four estimates and of course you get what you pay for. They were fine with the removal, but when it comes to the installation their attention to detail, common sense and customer service are totally unprofessional: 1. For the furnace main trunk line, instead of straight shot with minimal angles, they tried to cut corners and cobble bends to connect to an existing duct--which I made them redo. 2. The furnace exhaust pipe on their first pass was installed head height and Chris insisted that it needed to be that low so the moisture can drain back toward the furnace. Upon further questioning and suggestions he were able to raise the pipe closer to the ceiling. Another thing that had to be redone. Set a date to have that redone and they blew me off. The second time they came to fix it. 3. The electrical wire that connects the thermostat to the furnace, one of the workers accidentally pulled the wire out before connecting the thermostat--making more work by having to put holes in the drywall to pull a new wire through. At this point I didn't trust them to patch up the holes, so I did it myself. 4. The exhaust pipe for the water heater, same thing again trying to cut corners and cobble parts together to connect to an existing pipe. The connections were held together with "foil tape" which fell to the floor. Called them to redo and they blew me off twice. Finally go Chris to come out to fix. 5. The pressure relief valve pipe was not strapped and extended to drain outside. I called them numerous times to complete the job, but they never return my calls--so I ended up finishing it myself. 6. I decided to give them the benefit of the doubt and ask them to do the yearly inspection. Chris answered the phone this time. We set a date and as expected he blew me off. If you are looking for a HVAC contractor avoid Nasa Heating like the plague. read more

Chris did an excellent job repairing an aged thirty year old unit that was not turned on in over 12 years. I contacted over eleven places before selecting his company. Each company had an estimate fee and other various hidden fees. NASA heating and AC was the only company that did not charge this fee and was straight forward with the pricing. I highly recommend their services and will continue to do business with their company. Chris was a friendly individual that represented everything accurately and provided excellent feedback on what to look out for. Thank you for the great work! My family will now have a heated house for Christmas! read more

Nasa heating and ac is the real deal, no hassle no haggle competitive, honest and fair pricing up front. Chris and Mark were extremely friendly and knowledgeable and they're a really great team. They installed my new ducting in my attic with very little space and clearance to move in, but Mark took a deep sigh and went in like a champ for almost 4 hours in extreme uncomfortable heat, and got the job done as promised. Nasa was 30-50% cheaper then other bids I got, and I'm not necessarily a person who opts for the cheapest price, but when I met them I was so impressed by their positive attitudes and knowledge of my heating system I decided to hire them right away. You won't be disappointed with NASA and highly recommend them for residential heating and ac installation and services. I will definitely be using them when it's time to replace my furnace! read more

I've used Chris and his team on multiple residential projects. As G.C, I needed someone reliable I can count on to refer my clients to for repairs and new builds. I would recommend NASA heating and AC services to anyone who wants the job done right, in a timely manner, and anyone who is looking for a company that is here for the long haul. Thank you Chris! read more

They rocked it! Put in some insulation for us and we couldn't be happier. The process was pain free and the work was timely and efficient.

My parents wanted to upgrade to a nest so we were looking for someone who knew how to do that and wouldn't charge so much. My friend recommend NASA to us. They came to check out if we could upgrade Chris was so polite he was ready to start working right away. He put up our nest the next day. My parents were so happy with the nest! I'm so glad we went to Chris. NASA has called in to check on my parents about a month ago to see if we were satisfied with their work because if not they would come back and fix it. I'm so happy we found someone my parents can contact again just in case anything happens read more

I recently recommended NASA heating to install a commercial heater for small business. Chris the Manager and his guy Julio was so professional. Their response was quick, straight forward and honest with pricing. Please don't judge them or worry about their experience based on the low number of reviews they have, that thought was through my head when I found them too!! But somehow, my thought was there are just busy great ppl out there who does great work but just do not have the time to setup or even feel like it's normal to ask for a rating if we felt we were given great service. And yes, the only reason I would write this review was I received great service and I will spend the time to let others know. read more

Chris and his crew were great to work with. Very professional and the work was well done. I was very impressed with his attention to detail and how fast everything came together. He responded to my texts quickly, was able to work me into his schedule the same week and finished a day early. Overall I am very pleased with the work and will call again when I have future projects. Thanks again Chris!! read more

This guys are very professional at what they do. They get the job done in a very sophisticated way. They are very thorough and very dedicated to getting the job complete. They just recently replaced an Old furnace and installed a new one. My wife and I are very happy with the results. No complaints at all. We got all the equipment and paperwork to back up their work. I would highly recommended them for any Heating and AC work, whether it's repairs, installation or replacements. read more

They made an appointment with me, I stayed home from work, and they did not show up or respond to my text and phone call.

I highly recommend Chris with NASA heating and AC! I was searching for someone to give me the best quote on installing my Ductless Mini Split AC Unit, and NASA by far gave me the best and most reasonable price. Chris responded right away and was able to come out to my house the very next day. Like any homeowner during COVID, I am a bit weary about who comes in and out of my house. But when Chris arrived, I was very reassured to see he was wearing a mask and followed all COVID related guidelines, including keeping minimal contact, social distancing and leaving the area clean. Since this was my first time installing an AC Unit, I had many questions and Chris was very knowledgable and experienced. I would highly recommend Chris and NASA heating and AC and will likely hire them for future installations! read more

We had a great experience with Chris and his crew at Nasa. We needed to replace our 27 year old heater. We got three estimates. Chris offered us a high quality heater, along with a friendly and thorough explanation of all of our options. We have allergies, and Chris set us up with a great filtration system. Chris is an all around great person to work with. We will definitely call them again. read more

My unusual radiant hydronic system needed to be replaced. Chris came and looked at the problem. Despite the complicated situation Chris said they could replace the Baxi Luna boiler with a new efficient tankless water heater. His bid was reasonable and his schedule for this was within two weeks. Yay, my hero. I'd tried several other HVAC companies and NASA was the only one to submit a bid. I'm writing this tonight with hot water available for the first time in a month. The new A.O. Smith tankless hot water heater is beautiful. Thank you Chris and crew for the excellent work. read more

Chris and his crew are top notch guys. I had central heating installed where there was none before. They had it done in under a week. Always on time and cleaned up each day. They even removed my old ugly wall heaters and plastered and painted. It's like they were never there. Highly recommend. Robert A. read more

They installed my tesla EV charger. Chris gave me a competitive deal. Some other electricians gave me ridiculous estimates. I would recommend them. read more

We messaged NASA through Yelp after reading its reviews and Chris answered saying they could help and that they could come on the follow day evening. We replied immediately confirming the appointment and we sent him our address. However, he didn't reply anymore, not even the phone calls or messages we sent asking him what time he would come. We are renting our unit and it's not easy for us to schedule with the tenants a time to let an electrician come in, so NASA definitely disappointed us and they are not reliable at all. We do not recommend them. read more

I had a bad fas valve and I called this company. Not only were they helpful and polite, they assured me that if anything ever happened they would send someone out ASAP. Great company. Chris was very helpful and made sure that my family didn't suffer from this terrible weather. I called other companies before and not only were they rude, they were not as helpful as NASA heating and cooling. Great company for anyone having issues with their HVAC system. read more

Chris had our heater working again in less than 30 minutes! Our furnace had been acting up over the weekend so on Monday morning, we requested quotes from several businesses in the area. Chris was very quick to respond through the Yelp app and lucky for us, he had time later in the day to stop by. He arrived on time and didn't make any fuss when we kindly asked him to wear shoe covers in the house. Chris was able to diagnose and repair our furnace in less than 30 minutes. Once he got it up and running again, he made sure to stay an extra 20 minutes or so to ensure it continued to run without any problems. He even gave my husband tips on how to properly maintain our furnace so we could avoid future issues. As you can tell, Chris is very thorough. His prices are reasonable and we were very happy with his work. We wouldn't hesitate to recommend him to anyone! read more

For any job regarding air conditioners or furnace, I highly recommend Chris. Installation was quick, easy and affordable. Other companies I called for a quote were really trying to up charge me, and take advantage of my lack of knowledge on the product. Luckily Chris was able to explain everything from A to Z, and was great at troubleshooting and instillation. He relieved a lot of stress by assuring me that he wasn't trying to up-sell me. Plus after the job was done Chris called to check in, and make a follow up appointment just to give you that real customer experience and ease. Plus, he is always available and open to answer any questions. Bottom line they have amazing customer service, quick and easy installation, the price was more than reasonable, and the work was flawless. I would definitely recommend them to anyone and everyone! read more

After a lengthy back and forth, Chris and I were able to resolve the issue and I'm satisfied with the heater that was replaced. It did take longer than expected and caused unnecessary stress; however he did end up delivering and ai appreciate that. Thanks! read more

Nasa Heating and AC Services is amazing!! If you don't know the word, google it and you'll find them! Chris is definitely the type of technician you can trust to work diligently and quickly! Extremely capable, upfront about pricing, and honest. Got my heater going again within 1 hour. My partner reached out to him, and he went above and beyond for us and our pups, and fixed a few problems we didn't even know I had. Very knowledgeable and believes in doing the job RIGHT, not just doing it cheaply/quickly. I will always reach out for their services in the future. Thanks again!!! read more

Great service! Chris and his team were professional, informative and helpful. They did a great job and I highly recommend their service. Good value. read more

Took a chance on these guys, and I was rewarded. They quoted me a fair price, were easy to deal with, showed up on time and executed the work efficiently. Julio was very good and really knew water heaters, and easily dealt with some minor idiosyncrasies of dealing with a 70 year old house and a 15year old plugged up water heater. Chris Hernandez was pleasant and responded promptly when dealing with my communications. Two big thumbs up! read more

Our 50 year old heater finally stopped working. I contacted a bunch of heating specialist through yelp. Chris got back to me right away with clear pricing and his availability. When he came to our house later that day he really took the time to look at the furnace and talk through our options for getting heat back on in our house! I would definitely recommend NASA. read more

Chris and Julio were so helpful and prompt in replacing my broken wall heater that I felt the need to open a Yelp account and write my first review. I called and spoke to Chris on a Saturday with a broken heater, worried it wouldn't be fixed in time for my brother's upcoming visit. They took care of everything that day and for a reasonable price. While Julio was there replacing the wall heater I showed him my 19 year old water heater. Now I'm hiring them to replace that, and to bring it up to code as well. read more
