"Great. They contacted me right away. It wasn't an emergency but Iti was cold, so they still came first thing on the first business day. The technician explained what he was doing and why the prior repair done by somebody else probably failed. The rate was reasonable. It's been a couple of days and it seems the furnace is working, so everything good so far."

"The team at Smart Heating & Air Conditioning are second to none. Quality work and amazing customer service. Would recommend everyone to them for your heating and A/C needs!"

"Albert Nahman PHC installed new AC and Furnace for my house. I like them for several reasons -- 1. At first Tom explained in detail what equipment I need and how they work, and gave me a reasonable and detailed quote at end of the visit. 2. They offer interest free finance. 3. I got free upgrade for furnace when the original quoted is not available. 4. Their installer did good job, and cleaned up afterward. I highly recommend this company."

"AirGonomics Heating and Cooling has solved a variety of HVAC issues, including a full system replacement at my home and rental properties over the years. I have always been satisfied with their services."

"Kesar Gosal was extremely professional, quick, affordable, and reliable. I had reached ou tto him to install a furnace I had already purchased. Other contractor refused to do only the install and wanted me to purchase the furnace through them. Kesar agreed to the work and stuck to his original price even though I did not hire him for another 2 weeks. He came the very next day and installed the furnace without any complications. He was very polite and professional while onsite and explained what needed to be done. Cleaned up after he was finished and left with a smile. I will reach out to him again for any work I need done."

"Absolutely the best HVAC company in the area. If you are looking for a company for your HVAC needs, look no further. It is superb in every aspect: customer service, onsite specialist who did the inspection and quoting, technicians who installed the system. Their price is extremely competitive, especially for the high end systems. I was shopping for a 80% 2-stage furnace but I ended up getting a Lennox 99% variable-speed furnace because the price was too good to pass. But it is money well spent. It is so quiet and powerful. I highly recommend Air Sharks. They actually put a smile on our faces."

"They replaced our failed furnace with the same model, efficiently and at a very affordable price. The installer Bob did and outstanding job, and the QC checker Mizael did a thorough follow-up check of the installation and checked each of the furnace vents for adequate heat. The new furnace very quickly heats our home and is the right size for our home square footage. The Comfort Energy company not only gave us the best price, but is also furnishing two complimentary follow-up maintenance checks. This company deserves a 5 star rating."

"They were prompt and neat. Finished the job as expected. I have been using my new Trane furnace for three weeks now and every thing is working fine. I wish they had not used black ABS exhaust pipe or had painted it to match with rest of the room or used white ones."
