Just a heads up, they will only service equipment IF they installed it…read more I have never heard of a service company not willing to work on equipment installed by someone else. If you buy a house, you may not know who installed it. Last week Wednesday (1/7) I called because we had a mini-split installed (DIY) and I was told that before you turn it on, have an HVAC company come out and test it, check the pressure in the lines and then turn it on. When I called, the nice lady on the phone said that they do not diagnose or work on equipment unless they have done the installation. OK, no problem, I called their "sweet" competitor and they sent out a technician within 48 hours to do the job. 2 stars only because the lady on the phone was nice, although again, I am shocked that a service company will not do service calls

After our first great experience with David at DLO we decided to have him come out to take a look…read moreat replacing our furnace and air-conditioning unit original to the house 1983. 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.
