Value Heater Repair
Heating Engineers in Diamond Bar, CA
Average rating: 5 out of 5 stars13 May 2019
“There were a few hiccups but the company worked to resolve them the best and fastest they could. I am satisfied with my insulation and the price was fair. I highly recommend this company in my area to anyone looking for duct cleaning services.”
20th Century Air, Inc.
Heating Engineers in Diamond Bar, CA
Average rating: 5 out of 5 stars13 February 2017
“20th Century added a/c to our existing furnace, and the results have been great! It took them a single day, and they included a wifi thermostat. They were very clear in advance about what their work would and would not include, and their price was fair. We had the option of several different units, and the one we chose was slightly more expensive but more economical to operate. I would gladly have them back for any job, but two years later there hasn't been any need for repairs.”
Mackey Heating & Air

Average rating: 5 out of 5 stars12 April 2017
“I work for a property management company so I've experienced MANY HVAC vendors- Mackey AC has proven to be the BEST by far. Kevin is reliable, knowledgeable and honest. I never feel like their upselling a job when they come onsite. I recommend this company 110%.”
Equinox Air Conditioning Placentia
Heating Engineers in Diamond Bar, CA
Average rating: 5 out of 5 stars16 September 2021
“I don’t think I can honestly say enough wonderful things about this company. The technician came to our place within an hour after calling them and immediately fixed the problem that I was having with my ac that was not blowing cold air. He even explained the problem, and the repair charge was very reasonable too. This company will be the only HVAC repair company I will call for my HVAC repair needs in the future!”

“Quick and complete! This HVAC repair company was outstanding while attending my home HVAC furnace repair service. It was them that thoroughly ended my problems and assured me that everything now was back to normal. I can tell that this company and its technicians are highly capable and I'm sure that their services will be needed again in the future!”
Metro Heating Repair Anaheim
Heating Engineers in Diamond Bar, CA
Average rating: 5 out of 5 stars27 July 2021
“I have always been satisfied with the quality of the service provided by this company! I couldn't have been more satisfied with the professional manner in which the technician conducted himself when fixing our ac that was not working. His attention to detail was over and above my expectations. For that reason, I'd make sure to recommend their services to everyone I know!”
Yaeger Services
Heating Engineers in Diamond Bar, CA
Average rating: 5 out of 5 stars1 June 2017
“Yaeger Services came highly recommended to us by a professional whose job is SEERS testing of air conditioners. We worked with Matt, who was the epitome of professionalism and integrity. He dealt with our HOA, providing them with all of the information required for approval, obtained the necessary permit from the city, handled all of the details, and kept us updated by email or phone without our ever having to request any information. He was onsite the day of the installation, which was accomplished by a neat and efficient two-man team in less than a day. Matt was onsite again when the City Inspector arrived to sign off the permit. Matt and Yaeger Services handled everything for us. They even registered the warranties! Is it any wonder we intend to have them take care of future heating and A/C maintenance?”
Thomson Air Conditioning
Heating Engineers in Diamond Bar, CA
Average rating: 5 out of 5 stars13 March 2015
“Thomson AC saved our burning hides last year during a Fall heatwave. We have an older unit that honestly needs to be replaced, and that's all another HVAC company would tell me when we were visited to get a quote. Wouldn't even think about repairs. So I called Thomson. A technician came out and took a look at our unit. He was on time and clean! They all drive a big Thomson van that I see all over OC, so I can see they get lots of business. Anyway, he took a look at our old work horse, gave us a quote on replacement parts (which weren't cheap), gave us a little break on the price and did not pressure us to purchase a new unit. I would absolutely call them again if my AC breaks again, and if I'm looking to upgrade in the future.”
SIMS Heating & Air
Heating Engineers in Diamond Bar, CA
Average rating: 5 out of 5 stars28 May 2013
“We have been using Dan Simeroth and his company for over 15 years. He is responsible, professional and ethical on his repairs and recommendations. He handles not only HVAC issues but also can give repair bids for other maintenance items that are needed. We highly recommend this company.”
Go Green Heating & Cooling
Heating Engineers in Diamond Bar, CA
Average rating: 5 out of 5 stars11 December 2017
“As soon as the weather started to get cold, my heater broke like clockwork. After a few days, I couldn't take it anymore and called Go Green. They were very understanding and helpful about fixing the heater. The system was working again the same day and I'm writing this from the comfort of my toasty bedroom. Great service!”
