The home warranty company gave me dates of availability but Steve called me right away asking if he could come out the following day. He advised that my heater needed a cleaning, and told me what the issue was. I know he didn't try to upsell or provide unnecessary services as a prior serviceman told the home warranty company the same thing and I knew it was not covered Steve fixed the issue and cleaned the heater within 1.5 hours. He was extremely professional, showed me where the issue was and how it wasn't working. Great service and I would highly recommend.

Steve's office called seconds after the claim was filed, I had not even gotten off the call with the warranty company. That's some fast office work! Unfortunately no same day appointments were available so they set up a next day morning appointment. Steve showed up on time and brought all the necessary tools and parts for the repair. He was nice to speak to and highly focused on his work. The job was completed quickly and Steve avoided conversation until he finished the repair so as to maintain focus and reduce delays in the repair due to chatting. Having no A/C is no fun! Some reviewers mention rudeness and arrogance, we got none of that, maybe he was having a bad day on those service calls. He was very quiet during the repair process but pleasant and easy to work with at the end of the repair process. If you are looking for an HVAC contractor who knows their stuff Steve's company is a good choice to look into!

After 20-30 mins of evaluation, George determined that it was just ac units outside needed a deep clean. And wow what a difference it felt after his cleaning! Super chill air! In/out within an hr.

Our HVAC system stopped working out of nowhere, and they were able to get someone out pretty quickly--which already made a stressful situation a lot better. George was awesome. Super friendly, respectful, and you could tell he really knew what he was doing. He explained everything in a way that made sense (which I appreciated because I don't know anything about HVAC stuff), and he had us up and running again in no time. It's not often you get service that feels this honest and reliable. I wouldn't hesitate to call them again or recommend them to friends and family. Thanks again, George!

As I said on Google: I love these guys. They have earned my trust. Not only did they do a nice job…read moreon replacing our furnace compressor with a new unit, but when it broke a year later, they repaired it under warranty. No arguments, no fuss, no questions. "It's broke. It's under warranty. We will fix it." What's not to love about a company that does that? I plan to use them for our goofy refrigerator problems, and for my beginning-of-the-season boiler and furnace maintenance. The compressor replacement (actually, the entire outdoor unit) was sold to us at a really great price. They are competent and humble. I was speaking to their technician and he was explaining the sort of metering he had to do after the install (A/C is very complicated and weird), and I said to him, "Wow where did you learn about all of that?" He says, "In school- they taught me. It's hard. There are a lot of guys who don't understand but Astera doesn't hire them." It was a matter-of-fact conversation, and gave me quite the clue as to their business principles.

I saw him working - in addition to knowledge and experience he has a good working culture, and you'll rarely find it these days!!! He did a complete A/C system replacement for me. He quoted the project and after that explained all the details I was asking about (even I was asking quite a bit more than a usual customer would). As a result we slightly corrected his initial standard proposal to better fit my not quite standard case. His price was sure better than those big companies estimated. After being a customer of Allied Air Conditioning and Heating Corp. for 37 years and watching deterioration of service level there as well as a price increase I'm switching to ThermPro Heating and Cooling on a permanent base for all my HVAC needs. I can see that here you can talk it through and find solution (possibly even not a standard one) that will fit your needs and checkbook. Corporate America does not operate this way (it just cannot) - they have a set of rules and some company standards that they have to be within, but I, as a customer, do not care about. In addition to all I see that if we, consumers, will not support businesses like this one, we will be paying more for less service. So I strongly encourage you to consider ThermPro Heating and Cooling for all your HVAC needs! And I thank Erik very much for the good job he's done for me.

Mr. Duct sent Miguel out to clean our ducts. He did a great job. For those looking at duct cleaning…read moreservices, you should look for National Air Duct Cleaners Association (NADCA) certified shops. You should also shop around because some places offer bonus services that you may or may not need, or may even be hazardous to the occupants of the home, like sealants or chemicals. Check the EPA page on "Should You Have the Air Ducts in Your Home Cleaned?" for a thorough treatment of the topic, though note that it's much less enthusiastic about duct cleaning than people's subjective experiences, especially people with allergies or sensitivities, or if you've just done a remodel. I'd refer to "Is it worth it to get your air ducts cleaned?" on r/homeowners and "Is air duct cleaning a scam?" on r/hvacadvice. With that out of the way, Miguel cleaned our ducts quite thoroughly. He inserted the vacuum to the air handling unit. This would provide the negative pressure to ensure most of the dust and debris would go to the vacuum. Then he use a air compressor to knock loose the dust at each register and as far into the ventilation as he could push the nozzle. My registers unfortunately went up towards the attic, so dust was guaranteed to get knocked loose into the room, so we had to vacuum. This would have gone smoother if Mr. Duct had sent a partner with Miguel. Miguel was also very helpful in airdropping the photos of the ducts to my phone, which was important because we were trying to identify what might be triggering allergic reactions. For roughly $300, it was very reasonable. I would recommend Mr. Duct to those who need duct cleaning services.
