“Ryan, Mac and Bryan performed the install on our new AC and Furnace. They exceeded all of our expectations. We were impressed with their professionalism, cleanliness, and attention to detail. They took time to explain each step of the installation process and taught us how the new systems and thermostat work. Vince was a great salesman, he provided a thorough quote after exploring our needs and wants. Round of applause to all the Mr. Furnace staff. We highly recommend them.

Absolutely fantastic service from the prompt response to my request for service, the sales associate and finally Ryan and John’s installation of my new furnace and AC unit. They were all extremely professional, prompt, courteous, respectful and knowledgeable. At no point did I feel like my concerns weren’t addressed or that my questions not answered completely. Without hesitation I would highly recommend Mr Furnace to anyone. On another note Ryan was a fantastic mentor to John. Very patient and took the time to explain and train John as a new technician. Ryan is the type of mentor we all wish we could hire to train our new employees!”

Very pleased with my new furnace and air conditioner. The guys were in and out in four hours with minimal disruption. Big shout out to Anthony for being so brief in his explanations (my request because I hate long drawn out details) and for being patient with my scared rescue dog. He’s a gem.”

FAQs

Choosing an HVAC contractor isn’t easy. Therefore, to make sure you partner with someone you can trust, here is what you should look for: 

  • Years of experience in heat and AC replacement
  • Track record of success that is proven with positive customer reviews 
  • Knowledge of which HVAC unit is suitable for your home
  • Free consultation on repairs, maintenance, and installations 
  • A warranty on all services 
  • A price for services you require before any work has been performed

Don’t know whether it’s time to replace your air conditioning system? Check for these signs around your home: 

  • Your unit is blowing warm air 
  • The thermostat is not working
  • Your unit is making odd noises 
  • There is low air pressure coming out of your air vents
  • Strange odors are coming from your AC unit 
  • Your AC unit is leaking water
  • Your monthly energy bill is high 
  • Your unit is more than 10 years old

Your required air conditioning unit size to efficiently cool your home is based on its cooling capacity measured in British Thermal Units (BTUs) and the unit’s Seasonal Energy Efficiency Ratio, which will depend on the square footage of your home. 

New air conditioning units are designed to be more energy-efficient. Therefore, if your unit is older, it will require more power to cool your home than a new unit that needs less energy to do the same job. As a result, your monthly bill will be lower, and you will save money over time.
