Michael not only diagnosed and repaired the boiler in record time, but he was also kind enough to take the time to thoroughly explain how a hydronic heater works, and all of the necessary maintenance involved. Michael was extremely knowledgeable with all things HVAC. We were charged a very fair price for the labor, especially considering the weekend callout. Fast forward a few weeks, and we called out Michael to update some of the heater controls. Again, Michael provided outstanding service and corrected a few other issues with our hydronic system. Still highly recommended!

Update 4-14-2026 To finalize this exchange and summarize…read morePat's treatment of my family and I. I have been extorted by Robert, accused of fluffing the bill, and essentially told that due to Pat's mistakes I am no longer welcome to use the service. This last part is verifiable in the response given to me. To whomever is above Robert I want to clarify how this situation was 100% caused by your company and now I am being painted to be the villain. If you pull the phone record you will hear that my family and I never once asked for a discount. In fact Robert was adamant he make it right and reactively (as this was after the first screw up) offered to take this job on the chin. I encourage you to ask Michael, as he is a super honest employee of the conversations we had with him as he made a mistake and misquoted. I assure you he will be nothing but truthful regardless if he made the blunder. With all this being said I am now not welcome to use your service according to the Google commentator. For that I am bummed as the workmanship, when Pat's does show up has been historically a class act. I have contacted the BBB, and Angie's list due to the extortion and treatment by Robert and Pat's heating as a whole. I do not care what the outcome is but to sit back and be bullied due to Pat's mistakes, and Robert's incompetence is absolutely ludacris. To the owner, if you want to make right terminate Robert's employment and I would be more then willing to continue business as my family has done so for the last 20 years. Robert has done nothing, and I mean nothing to make any of this experience pleasurable. Even eating the job, which your team did as Robert promised, came at the expense of extortion, and painting my family and I as the villain. I must say that the treatment of my wife and dying father (the one sitting home waiting for Pats delaying treatments to be available) lead me to get involved. The owner is welcome to call my dad and he will give you my number. I will not discuss anything with Robert as 99% of these issues came from his failed management. To any users reading this know I do this to show you the caliber of people Pat's employees. In the unfortunate event an issue does arise that is out of your control it is evident Robert will say whatever it takes to try fixing the solution but do minimal to help. A liar is a liar, beware before making any Deals with him and I will encourage anyone to get anything he says in writing to expedite the back and forth I had to do to get him to honor his commitment.

I am very happy with the service provided and Aire Serv will be the only one I deal with from here forward. It is nice to know that you are actually getting what you pay for when they come because everything is explained to you in terms you understand! Thanks Again for the great service!!

The tech, "made adjustments", got the furnace to ignite, and refused to tell me how. He then consulted with his boss and returned with a $496.00 bill. This is about 3x the amount of a common service call. He added that they would apply the $496.00 to the price of installing a new inducer motor, or a new furnace. Making the installation of a new inducer motor $904.00. I spoke with a supervisor who said it was more than a service call because "adjustments" were made, and the heat is now on. I consider this very sneaky and out of line. They never told me this service call would be $496.00, or any price for that matter. It was a sneaky rip off that the consumer should be aware of. I should have paid no more than $200.00 for that service call. Future customers should be aware of this tactic.

Than he sent Elizabeth his admin person to do his lying for him. They now demand i remove the entire ceiling and verify there is no mold or asbestos before they will return. We discussed the condition of the basement, specifically that there is soke mold and likely asbestos wrapped pipes. The morning he arrived to do the job he immediatelyadmitted he screwed up. He assured me he would do the work anyways as it was his mistake. Now he won't respond to messages sent directly to him, and Elisabeth is like dealing with a child who will not admit they are wrong. Despite the very good reviews, it has been a nightmare trying to get this company to follow through with what they said they would do. I strongly recommend you look elsewhere for your work.

This past Monday he installed a new Honeywell T10 Lyric thermostat. He tied this in to my existing bypass humidifier to automatically control it to minimize window sweating in the summer. The new controls required a new wire to tie the thermostat to the humidifier. Tom efficiently ran the wire from the main floor to the basement. The T10 can also control via remote sensors to assure adequate heating and cooling. I am very happy with the thermostat, and how the system operates!
