Bell Brothers tech stated our heaters gas valve was completely broken and then tried upselling us a quote of $32,000 for a new unit. I'm so glad that Chris found the issue and saved us tens of thousands of dollars. We're canceling our Bell Brothers service and going with Delta Sierra Mechanical! This is the second time that Delta Sierra Mechanical has come to fix something that Bell Brothers techs messed up. Thank you Chris for helping us out.

We had a HVAC tune up & inspection last month. Our traditional original gas furnace & A/C were…read morestill running but we're barely able to keep up with this summer's heat. We learned about the Federal tax credit that expires at the end of this year & all the new regulations for Title 24 in California. We decided to upgrade our system now instead of next year because of the higher costs in 2026 for all the new rules & regulations. We decided on a RUUD heat pump system from Love's Air. They were great with the entire process from financing to installation. The day of the install Love's text me a photo of one of the installation team members, Xavier. Followed shortly with a phone call from him. Xavier, Wyatt, & Tim all arrived on time as scheduled. They explained everything about the installation & each went to work with their assigned duties. Every team member was respectful & took excellent care of our home. Floor & shoe covers, furniture & clothes were covered anywhere near the areas they were working. Took about 6 hours to demo the old system & install the new one. Everything step was thoroughly explained as they worked through the day. The new system included a Nest thermostat & as Xavier helped me setup the Google Home app, Wyatt & Tim cleaned up everything. Swept up the driveway & left the home cleaner than when they arrived! We couldn't be happier with our new heatpump & it's worked perfectly for 2+ weeks. We've had the first of 2 inspections completed with no issues. We've can't recommend Love's Air enough & extremely satisfied with the quality of workmanship & professionalism of the entire team at Love's Air!

Update- for the owner! 1. We understand our unit is 12-13…read moreyears old and we were given options last year but we were told if units working fine then we do not need to take immediate actions. 2. Prior to yesterday's visit, we just had a maintenance performed last week and all was good. No immediate recommendations was given. 3. If as your said this could happen, shouldn't your technician go over the possible issues with us before he start operating? He was here for less than 15 mins and broke the compressor. 4. I am in awe that after management showed up they told us it's just bad luck and they cannot take any responsibility. Then proceeded to give me a quote for 6-7k for a replacement compressor. 5. I had a working AC and your technician showed up, within 15 mins, messed up my AC and give me a quote for 6-7k? If you were me, what would you say? What is fair is fair, in this hot weather and I just had a surgery and I have no AC and now what do I do? I also have a feeling it's not the first time this tech messed up. 6. I will attach my service export a week ago from your company and all the research I have done! This is the 1st part of my review. We have used loves air to maintenance our AC unit for 3 years now. A week ago the tech Joel showed up and said everything was fine. We did have to add some freon a year old and was told we have a small leak & provided quotes. My husband decided to go forward with the leak & add more freon. Yesterday around 11:20 Joel showed up, as he was adding liquids, the compressor made a hizzing sounds & Joel attempted to cool it and it made banging noise & the whole thing stopped working l. My husband immediately came inside and told me" I think he messed up" and got very worried , he spent about another hour working and cooling and trying to get it to work and no luck. He came back and told us, the compressor went bad the same time he arrived it and quoted us over 6k for a replacement. I said no way, my AC was working before you showed up, it went bad because you broke it, probably because you poured it too fast. ( we chatgbt is right away as he was attempting to fix it) he said no, it's just bad luck. We proceeded to call office and a supervisor came out and told us the same thing, said just bad luck and they can't take any responsibility.I was in shock, I told them I do not have 6k to fix a part they broke and now I have no AC. I called office again asking for the owner and was told owner does not handle this and we will have a conference call Monday morning with office manager. I know this guy broke it and doesn't want to take responsibility. If owner see my review I hope you have the decency to contact me and make this right.

David explained the difference in the units we could choose from for this size house. A quiet A/C was important to me and my boyfriend wanted all the ducts under the house replaced. Vents pipes where replaced and different duct sizes were strategically placed under the house. The air conditioning unit is so unbelievably quiet. I love it! It feels good to turn on the heat/air and know it is blowing clean in the house. A big upgrade after 33 years! Hopefully this efficient system will bring down our PGE bill. David is not a high pressure sales person which I like. His prices are reasonable and his team is prompt and know what they are doing! I highly recommend him!

4/5: Took 3 visits for the technicians to figure out what was wrong with HVAC…read more Juan came out first and thought it was the thermostat, I didn't think so because the code that keeps lighting up on my HVAC was 26, from the blinker light message which is the burner unit. Before the technician came out, I did tell Air Tech scheduler that I have to leave by 1130am that day for work and technician came around 9am. Anyway, when I got home from work, the heater didn't turn on because thermostat was set to a specific temperature and inside the house was at least 4-5 degrees colder. Over the weekend, I left a message and I think it was Kim who called back. 2nd Technician came out and it was Nathan. He had to leave and problem wasn't solved and he ran out of time and had to come back again which he needed authorization for so I don't have to keep paying for the same visit when the problem wasn't solved. 3rd Visit: Nathan figured it out and solved it. It did took them 3 visits which was almost 6 hours of my time with approx. 2hrs each time. I'm just glad Air Tech's technicians figured it out finally and didn't go with the MOST Expensive solution for the client first. I tried a different company before Air Tech and they definitely went with a more expensive solution to my HVAC problem. Overall, I'm still pleased with Juan and Nathan that they were able to solve my HVAC problem of why the heater wasn't turning on. I waited 2 weeks before giving a review to make sure my HVAC is working fine, which it is and that's what mattered most to me. The technicians were great! Knowledgeable and both Juan and Nathan didn't mind answer ALL my questions on HVAC and taught me few tips. I gave 4 out 5 because it took them 3times.
