I went online and found DeNardo Heating and Cooling. He is a certified contractor with several brands. I called and left message. He called me back in 20 minutes. I explained the situation and he said he would look at it the next day He called me the next morning to confirm my appointment and was promptly at the service address. He was there for less than 20 minutes and showed me the problem. The next day he returned on time and made the required adjustments and repairs. The system is now up and running. I cannot even begin to describe how relieved I am because this is a commercial tenant that had no heat in their business. If you need a new HVAC system or service this is the company you want..

Chris arrived on time (a big plus for me). He gave us excellent advice, a true expert. They coordinated installation at my convenience. Manny and Dan installed the units -again - arrived on-time. They said 7AM - and they were unpacking their equipment by 6:55. Both of them were so nice and friendly. Their work was clean and even suggested wrapping the units since the hardwood floors were going to be refinished the next day. Excellent idea! saved us a lot of headache if all that dust got in the units. Would DEFINITELY CALL THEM AGAIN!!!!

Above all , important to me, they were neat, if I was not there to see it done there would not be a trace to follow. The chimney liner, the flu plate replacement and the installation was done quickly without a ' hitch.' The stove is much more efficient than the fireplace, too. A-Z is highly recommended, I am a fan.

If your chimney sweep is not taking the whole stove out in the process, they are not doing you any service! The A-Z team was very thorough and was able to show us the condition of our liner and some issues ignored by the previous so-called inspections so we were able to get all of it addressed to prevent future problems. They also went above and beyond to get to the bottom of our stubborn damper handle, getting everything working smoothly again. Pricing is reasonable, and the guys were neat, friendly, and really cared about doing the job right. After the cleaning, we had them install a new liner and our stove is back to operating efficiently for the first time in years. Highly recommend A-Z Chimney Sweeps!

He gave his honest opinions of what could be replaced and what the rough costs were for each component plus labor. He also explained what he thought was the best option to keep our current system running at it's best, which I chose to do. He re-gassed our unit and added a startup capacitor which seems to have done the trick! The outdoor unit kicks on easily, runs quiet and consistently now. And of course the AC blows ice cold now.
