Excellent service

I needed a new furnace and air conditioning unit after my old furnace conked out. 303 Heat came out immediately gave me my options fixed everything the next day. Not only did they do a great job but they made sure I had space heaters so I wouldn’t freeze the night before everything was changed out. Professional and personable service.

Exceeded expectations!!!!

Years of experience from Jarred made an enormous difference today! What I was told would be a complete replacement from 5 other companies, Jarred fixed in a short amount of time for nothing compared to what a replacement unit would cost. I am speechless that I went without a a/c all summer and today Jarred changed that thanks to his expertise.

303 Heat is a lifesaver!

Our AC went out in the middle of a heat wave (on my wife’s birthday). April managed to squeeze me in that day, due to an unexpected opening in Jared’s schedule, and she helped diagnose the problem (low refrigerant) over the phone. Jared was very knowledgable, courteous, and professional and had our AC up and running again—better than it ever has—within hours of my call. I can’t recommend them highly enough!

Customer said she could hear a clunking noise when her furnace was running. Found that draft inducer motor was bad. Replaced draft inducer with capasitor included. Draft inducer vents flue gases and provides fresh air in furnace. Due to safety reasons they need to be replaced if damaged.
