Get matched with top furnace / forced air heating system install or replace pros in Diamond Bar, CA

"We needed our 16-year-old HVAC unit replaced, so I narrowed my Angie's List search down to seven Heating & Air Conditioning companies. The ones I chose all had an "A" rating with good reviews. Of those companies, two of them never returned my call, and one didn't work in Los Angeles (it's in Burbank but doesn't work in LA--go figure!). When I called Air-Tech, Heather, the Administrative Assistant, answered the phone--very friendly--and scheduled an appointment. Alex Fish was the Comfort Specialist that came to our home. He was on time, and called me on the road to let me know exactly when he'd arrive. Alex is very knowledgeable; studied every room, looked in the attic where our furnace is located, and examined our condenser and its power supply. Then we sat down and he showed us an illustrated booklet of a house that describes just how an HVAC unit works in a typical home. He walked us through the different systems and gave my wife and me options. He called the office to see if we qualified for an LADWP rebate and a Lennox rebate. We did. None of the other companies we'd seen were this thorough. Before he left, he had written out a detailed proposal including model numbers, what they do, the all-new gas piping, and drain and refrigeration line specifics, etc. Alex was the only person we had seen that wrote a complete proposal before he left the premises. A few days later, I called Alex with additional questions, and he talked to me for 20 minutes answering every question and concern I had. The job took a week to complete, and Carlos and his team covered the work area each day, were very professional and cleaned up at the end of the day, like they had never been there. Many of the technicians have been with Air-Tech for years. To me, that really says something about the company. My wife and I decided to go the permit route. Air-Tech pulled the permits, scheduled the duct testing (we passed), and Heather informed me of what was required with respect to smoke detectors, carbon monoxide detectors and their proximity to any ceiling fans in our house. Because of her heads-up and the outstanding workmanship of the Air-Tech team, final inspection was a breeze. Two techs even came out to double-check everything before the inspector arrived. I can't say enough about Air-Tech. A company that is honest, professional, and does excellent work. For any heating or air conditioning needs, Air-Tech cannot be beat."

"Excellent customer service and fast! I highly recommend them, if you need a new system or maintenance this is the company to call!!!!"

"Top energy solutions did a highly professional and skilled job in installing two furnaces and two air conditioners and also remove and install new attic insulation in my home. One furnace was gas and one was heat pump electric. If the installers were supposed to be on the job at 8:00am they were here. The installers were highly skilled and cleaned up at the end of each day.

He diagnosed the problem very quickly, on my very old system - he even suggested further improvements - and was able to repair it a few hours later. Ray was the first technician to service this unit, and there have been many, whose word I feel I can trust. I highly recommend him to anyone in need."

He explained the need for a new filter in the heating unit and showed me photos of the unit located in the attic. He also offered to do a friendly deed for free, which I greatly appreciated, He’s a great asset to Service Champions!"

"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."
