I waited five days for this company to come look at my air conditioner. I took off work the morning of the appointment, which was confirmed two days earlier. I was on a conference call while waiting for them to arrive, when they left several messages. When I was able to call them back, they told me the technician moved on to another appointment because I didn't answer the phone. Then I got hung up on by Tina. At no point was I told the appointment needed to be confirmed again the same morning. TERRIBLE customer service.

Fantastic company. I called this morning because my heat was not turning on. The female who answered the phone was very polite. I called around 8:15am and a technician arrived to my home within 30 minutes. The technician Kyle was very nice and answered every question I had. Kyle solved the issue with my furnace and explained everything as he was servicing my furnace so I would be informed and in the loop. Kyle replaced my air filter and cleaned my furnace by vacuuming all the dust and wiping everything down with a disinfectant wipe. I had a great experience!

This company was used to install the heating and air conditioning in the house we bought that was gutted and redone due to a house fire. One of our upstair rooms has zero air flow. It is hotter than heck in the summer and there is not flow right now with the heat on. We have had them out a couple times this summer to investigate the problem and it was discovered that the duct work was missed going to that room.

They supposedly installed the duct work but There is still no air flow going to the room. Now we are told it is our responsibility to fix the problem which could be a few hundred dollars. We will never recommend this company nor will we use them to fix future problems. They claim that everything had to be put back exactly the way it was (because that's how insurance claims work) prior to the fire but the house was gutted and there are new things in the house that weren't here before the fire so it can't be exactly like it was. We have now contacted a different company to service our furnace and we will ask them to do future work on our heating and air conditioning needs.
