Furnace repair with careful diagnosis and clear options

"Chris is amazing! He came out and diagnosed correctly the issue with my furnace. Installed the correct part to fix the furnace and we were up and running within a couple hours. I would highly recommend Chris and his company. He did not try to upsell me on anything and just did what was necessary to fix the furnace so the price was great as well."

"I couldn’t be happier with the service I received. I came home from a trip to a freezing house on a Sunday evening. Chris was able to come by that same day within the hour I called. He is very knowledgeable and was able to get our furnace working again. I definitely recommend Sullys Heating and Air to anyone needing HVAC services. He truly went above and beyond."

Furnace Repair questions

Can Sullys help with a furnace gas smell or CO concern?

Yes, but if you smell gas, leave the area and contact the gas company first. Reviews mention furnace gas valve and CO safety checks after the immediate safety concern was addressed.

Does furnace repair always mean replacement?

No. Sullys starts with diagnosis and explains repair options first, especially when a failed part can safely restore heat.
