AC Installation & Thermostat Installation in Santa Ana

"Total Home Environmental HVAC helped us replace our old condo AC unit. They were professional and polite the whole time. They were the only outfit that quoted me that I didn't feel was trying to sell me, rather they gave me a walkthrough of the entire job and everything they'd need to do. I like to know how things work and asked many questions, and the rep who was doing the initial quote, Nathan, was happy to keep explaining things to me until everything made sense.

What particularly impressed me was what they did when the thermostat they brought was faulty: Gordon tracked down the factory representative for the LA area, asked him to test the setup themselves, and on discovering a fault got them to get a new thermostat out the next day.

The whole team from start to finish was wonderful, I am happy I chose them and happily recommend them!"

"We have been wanting to get a new heating system for our home. Our niece recently had her system upgraded and she was very pleased with Total Home Environmental service. We decided to contact them and they explained all our options. We decided to not only get a new heating system but added air conditioning as well. Sure glad we did as I never realized how the temperature in your home can affect other areas of your life. It seems we are sleeping better because of the controlled temperature. The whole experience was very positive from the planning to the actual installation. Definitely would recommend this company for any service/installation you are considering."

"Nathan and Gordon at Total Home Environmental are lifesavers!!!

I was facing estimates of $10,000 to $20,000 to replace my entire AC and heating system but instead they indicated that my 25 year-old AC compressor could be resuscitated by thoroughly cleaning the terminals and adding a 5-2-1 compressor hard-start assist kit.

No other HVAC technician that came out gave me this option but they pulled it off for a fraction of the price of a new install!!! They are honest and knowledgeable professionals! Thank you so much!!!"

"I spoke with Gordon on Wednesday about repairing my Carrier AC furnace. After explaining to him the symptoms of my unit, he said he didn't think it was the motor. He sent Nathan out the following day to diagnose the furnace and it turned to be the motor. The wheel needed cleaning as well. Nathan took the motor out and returned the following day to complete the job. Gordon and Nathan, both, came across as being very nice, knowledgeable, and professional. They didn't pressure me into purchasing something I didn't need, like others had attempted to do. I'll give these guys a 5+."
