When to Replace a Furnace or Central Air Conditioning Unit

When to Replace a Furnace or Central Air Conditioning Unit

Not sure when is the right time to replace your furnace or air conditioner? Check out the most common reasons to replace your Furnace or Central Air Conditioning Unit.

  • The furnace won’t heat the home since a major, out-of-warranty component has failed.
  • Rooms heat unevenly – as your furnace ages, it can become difficult to maintain even heat distribution. If the furnace is overheating or the burners are rusted, it will shut-off prematurely and cause uneven temperatures in your home. A Modulating or Two-Stage furnace will heat you home more evenly than a single stage furnace. They are also quieter in when operating lower stages.
  • You’re constantly having to repair the system
  • You struggle with summertime humidity problems continuously – the furnace blower motor may not be a variable speed. VS motors help ACs in Ontario dehumidify better in the summer.
  • Energy bills are on the rise due to increased consumption, so efficiency is failing (independent of the weather) Remember – Furnaces use both Gas and Electricity. The blower motor in your furnace should be an ECM, which uses considerably less than standard PSC motors. ECM motors are mandatory for furnaces installed in NEW homes in Ontario.
  • Your system becomes noisy and develops hums, rattles or buzzes. These are internal noises – not noises in your ductwork. It is important to differentiate.
  • The furnace heat exchanger is cracked. Make sure it is a real crack! Many companies falsely diagnose this in an effort to make a sale.
  • You see signs of excessive dust, dirt, soot or rust particles in furnace venting or on the burners.
  • Your system is over 15-20 years old – this varies greatly depending on the system’s maintenance and usage. Newer equipment can increase comfort and energy savings.

Our furnace (geothermal heat pump) seems to be able to keep up easily, even in the worst temperatures. For example, the other day it was down to -22c outside, but inside my two toddlers keep stripping their clothes off (they thought it was funny). There is no question geothermal can keep up. What a great system. Thank you again for what I consider the perfect install.

Pricing was competitive and the great referral were the deciding factors. Every one of the people at the job site were courteous and respectful.

Cindy and Bian Coughlin, Newmarket, ON

We are very happy with our system both heating and cooling. I think I have done the math right. I can't believe we heated our home for a full year for only 278.46
