Get matched with top thermostat installers and replacers in Los Angeles, CA

"Trinity Heating installed a new thermostat in my house. The technician, Jimmy, was professional and courteous. After the installation he took the time to explain to me how to set up and use the new thermostat. I’m completely satisfied with their service and will use them again if needed."

"Service was great and pricing very competitive. Nick Knuth was very knowledgeable when he came to do an assessment of the work to be done, and answered all my questions I'm a very clear way. The techs worked pretty quickly and efficiently when installing the new unit. Deisy and Emma from the office always made sure that things were taken care of and went above and beyond with follow-ups and updates. I would definitely recommend them to anyone who needs this service."

"Guil installed a kitchen faucet. He was kind and efficient. I would definitely call him again. Thank you."

"Mr. Avery called me and knew what I needed. He came out and was here in 15 Minutes. Mr. Avery was happy to give a free estimate, when everyone else that contacted me was not. Most others wanted a minimum of $80. to $90. Mr. Avery made a call to his Business and made sure they had the Part in stock that I needed. When he returned, the part was installed within an hour. He stayed to make sure that everything was safe and worked as intended. He was very professional and had a good sense of humor. I recommend 'Just Be Cool Supply' to anyone who needs Furnace repair. Mr. Avery is a Licensed Professional and the price was very fair. I will call them again if needed. Thank you Mr. Avery."

"DNA replaced the water pump.My mother is very satisfied.She know have cold air again."

"I highly recommend this company. Penguin heating & Air was very quick to respond to my request, fast text reply, sent them pics, they replied with a quote, which was way lower than anyone else on this site, or even our regular guy that we normally use, we scheduled an appointment for the very next day, which was today, he also finished the job the same day! David did a very good job, very professional. Despite a terrible rainy day, he got the job done. When he was done he walked me through with exactly what he did. He also quoted me for a service on an existing unit and his quote was almost $200 less than what our regular guy charges us... We will absolutely be using this company again."

"I first used Patagonia HVAC when my home AC broke. Guillermo, the owner, responded promptly and provided a quote for the repair. He worked with me to find the best new system within my budget and completed the installation within days. He was incredibly professional, and my AC has been working wonderfully ever since! I later hired him when the AC went down at my grocery store, and Guillermo had it repaired the very same day we called. I couldn’t recommend Patagonia HVAC more highly!"

"There was just miscommunication in the beginning. I called to confirm my appointment as the technician was now late. They didnâ t have me down for that day or any record of my call. I then had to wait for parts to be ordered after diagnosing the broken freezer. I didnâ t know if he was going to order it. He said to call the office and tell them to order it which seemed weird. Then I couldnâ t pull out the refrigerator to unplug it myself in order to let it sit for 24 hours defrosting once the parts were in.. I was told on the phone that I had a circuit to the fridge that I could turn off. He had never seen my outdated box. Finally had it repaired which was quick at that point. Knowledgeable technician though."

"Being a nice guy and feeling ripped off by a contractor is two very different things. We chose Michael Howard based on his response time , being personable and reviews. He's a very nice guy but in the end felt ripped off. We found that our initial interactions was very pleasant. He couldn?t determine with his assistant or figure the problem of our central heating unit and then told us we needed to replace the entire electrical circuit board. Cost was $750. He replaced the board and it still didn't solve the issue of heating up. He then determined that it was the motor that was the issue. Additional cost to repair $400. What was frustrating was that after speaking with other reliable sources while the job was taking place I asked Michael Howard for the old circuit board. He claimed that I told him to discard it. Not true at all. It was a red flag when a contractor is making up a story and calling me a home owner a liar. Why would I tell a contractor to throw out any parts until the job was solved and completes ? That truly concerns me as a home owner. Why would a professional discard the old circuit board fir the entire heating system before the job was finished ? My neighbor who's a contractor wanted to review the old circuit board. Then a day later Michael Howard returned with parts for the motor. He insisted and needed a confirmation of payment before he would repair the motor. Wanted me to sign an agreement when I questioned his judgement and concern that he might have replaced a circuit board that was perfectly fine since he later discovered the motor issue. I went up into the attic and found the old board. I asked him to now try the old board that I found discarded in the attic ( same part he claimed was discarded ). He told me that once he put in the new board it would be impossible to return it to the supplier that he purchased it from. Even with several hours of purchasing it. I asked him to show me a receipt and that I would call the vender. He refused. Ok so he didn't want to show me the receipt. When I looked up the part on line it sells for $90. So his mark up is 600%. I understand the time and labor but it was not very long. He then told me he would not charge the $400 for the parts for the motor. Wow. Bottom line is that when we later replaced the old board to test it , it worked fine. The real issue was the motor. The fact that he didn't want to make the effort to return it to the supplier with 24 hours is because he wanted to make the money. Clearly. Willing to not charge for the motor parts doesn't make me feel any better. Just made me recognize how much I was being ripped off. . And doesn't give the confidence to ever use this contractor again or recommend him regardless of all the terrific reviews."
