We had no idea when it was last serviced or if it had ever been serviced at all. Henry gave us a very fair and competitive price for a tune up. Upon Henry's arrival, he was friendly and professional. He opened the furnace and showed us the burner. He explained it was in great condition considering the age of the unit and it didn't need servicing; although, he did clean up around a few areas around the burner. The blower motor was slightly wobbly, and once again, he explained it was still in good shape considering its age. He proceeded to the back patio where the condenser was located. He noted the unit was very old and that particular Freon is no longer available for servicing; however, he stated the unit did not need to be replaced just yet as long as it's blowing cold. Henry indicated despite our units being way past their anticipated life expectancy, they were clean and blowing hot & cold just fine. Therefore, no servicing was recommended and he did not charge us anything. We are impressed not only by Henry's friendliness and professionalism, but also by his transparency and integrity. Many other companies would have hopped on the opportunity to upsell the service or even sway us to replace our system right away, but Henry gave us peace of mind to give us time and to save up for an inevitable replacement in the future with Therma Tech. Thank you so much, Henry! We will definitely contact you again in the future and recommend you to all our family, friends and coworkers.

He was friendly, courteous, on time, and used photos to help us see what the areas of concern were. He carefully explained maintenance options, including a service plan that would take care of annual visits for a very good price. he also discounted the service price, and we are very happy to have had the work done affordably. The coils and other parts were cleaned very carefully with the correct cleaning fluid fluids. They did the work quickly and we were not inconvenienced at all. The system is running great right now, and we are all set for the AC to be more efficient during the coming summer. I highly recommend IRBIS Air Plumbing and Electrical

I wish I had written down the name of the operator who scheduled my appointment but she was polite, professional, and courteous. She went above and beyond to find an appointment that worked with my schedule. She called back as promised and I was never left hanging or waiting for information. 5 stars for the operator, thank you! My technician was Victor who arrived during the scheduled time window. He was very knowledgable about the HVAC systems used for the homes in my neighborhood. He was able to quickly confirm the issue, diagnose the problem, and find a solution. He then performed a series of tests to confirm the issue had been solved. During each step of the process he explained what was happening in a way that was easy to understand. I now have a much better idea of what my system is doing and how it operates. 5 stars for Victor and I'm grateful for his service.

Disappointed after reading the reviews. These guys are in the same town. I figured I'd give them a…read moretry for installing an adding a mini split addition to supplement hot/cold spots in my kitchen. Not only did they not listen to my needs, the whole time they offered solutions that cater to what they want instead of what I want. 1. They recommend dual zoning which cost about the same amount as installing a new mini split. I have a single state HVAC which isn't recommended for dual zone install. 2. They keep pushing for fixing/upgrading central instead of installing mini splits. 3. They keep asking for my budget (red flag), talking up high end units (red flag), talking down low end units (red flag). Look, we all know Mitsubishi and Daikin are the top of the line. However, the cost of DOUBLE of the price of lower end models isn't due to just superior quality and technology. Heat pumps and mini splits are not new technology. One isn't vastly superior to another. Yes, it may be better, but not double the price better. The cost are always due to the commissions and kickbacks for these installers. That's marketing and salesmanship, but please be more transparent next time. Finally, I asked for quotes and options so I can decide. The person walked away disappointed and I suspect they think they lost a sale because of the way I did not want the highest end models and stayed firm with my mini split request. I sensed the guy walked away disappointed. Yet I still expected a courtesy quote like the other installers. They never sent it. I was not surprised. In the end, I decided that a whole system upgrade to mini-splits (30% more efficient just from being ductless alone) with rebates made more sense instead of add ons to existing system. But these guys did help me cross them off the list and went with the installer who actually listened to my needs and gave the recommendation and options that I wanted. I do not recommend these guys. They will push for the highest cost system and will ghost you if you appear to be knowledgeable enough to call them out on it.

Five Stars - Honest, Rare Service…read more Sal from Cost Less Heating & Cooling came out to check my heater, AC, circulation, and vents--the whole nine yards. He was thorough, professional, and took the time to actually explain what he was looking at. Here's the part you almost never hear: he told me I didn't need anything at all. No upsell. No scare tactics. No "while I'm here" nonsense. And he didn't charge me a single dime. That level of honesty is unheard of these days. If you're looking for an HVAC company that actually puts integrity first and doesn't try to sell you something you don't need, this is the one. Sal earned my trust, and I'll be calling Cost Less Heating & Cooling again without hesitation--and recommending them to everyone I know. Highly recommended.

Michael came out to my house and walked me through the pros and cons of a heat pump HVAC. For my home, the extra money made no sense. I really do not need central AC. We then talked about a new Carrier, high-efficency furnace. That was exactly what I needed. I also opted for the Ecobee Smart, wi-fi enabled thermostat. I am extremely happy with everything. The price was right. The installation was flawless. The post-intall QA walkghrough, by Johnny, went really well. ThenI worked with the folks that checked all the boxes post-intalleation.

Michael Calvey was a joy to talk to. Thank you to Johnny, the project manager, and the folks from HOPSTER that facilitated the post-installation test and inspectioin. From start to finish I met with Michael on February 12th. The 16th the new furnace was intalled. February 17th Johnny did the QA walkthrough. February 18th HOPSTER did their pre-test and inspection walkthrough. The HERS test was done February 23rd. March 5th the city inspection was complete. I will continue to use Calvey for annual maintenance

Their work was outstanding as they sealed off the entire garage during the demo with a negative pressure system to avoid any asbestos contamination. The entire job was completed in less than 3 days start to finish and the quality of work was impeccable.
