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!

Mike and his team successfully installed a Daikin VRV system in our home literally right before our old unit died. His team of installer/techs not only were cordial but extremely knowledgeable. As a business owner myself I am not shy about the cost of the solution we provide. I am a firm believer of "you get what you pay for". This fit the old mantra to a T! We had quotes ranging from 5k to 17k. No one knew the product as well as Mike and no one offered multiple products like he did. It was either cheap or the extreme. We are very happy with the installation, product, and responsiveness that Compass has provided to us. I can confidently recommend Mike/Compass to anyone looking for a quality product and install. Best part of all. The Daikin unit is so quite that you have to stand next to it to hear it run. It is very impressive and efficient. Compass Heating & Air - 5 Stars all day!!

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.
