Should I Repair or Replace My Heating System?

All homeowners find themselves answering this question eventually. The answer, however, is different for each home and set of circumstances. We’ve put together a quick guide to determine whether you should repair your heating system, or replace it instead.

Homeownership comes with having to make tough decisions. While we’ve all heard that investing in a home increases its value, deciding where and how to do that can be a tough choice. Should you finish the basement? Replace the countertops? The answer isn’t always clear.

When it comes to your heating system, the decision-making process gets even harder. Unless you’re a trained HVAC technician, it can be tough to tell whether a malfunctioning furnace needs new batteries in the thermostat or a more comprehensive repair. For homeowners with older heating systems, the decision often becomes whether to repair the unit or replace it entirely.

Much like an old car, furnaces show signs of failure before they actually fail. By paying attention to the performance of your older furnace, you can start preparing for the purchase of a new unit before you need it. You’ll also reap the benefits of enhanced comfort, lower energy bills, and more.

Our experienced technicians can help you make the decision if you’re unsure whether to repair or replace your furnace. Schedule a Diagnostic Service Call today and we’ll come out to inspect your system!

  • The cost of repair is too high
  • Long history of repairs
  • The unit is over 10-15 years of age

You Should Repair Your Heating System if:

  • The repair is relatively cheap and simple.
  • This is your first need for repair
  • The unit is under 10-15 years of age

Long-Term Savings on Your Energy Bill

After each season of usage, a furnace develops wear and tear from the strain of operating, while it also begins to collect dust and dirt build-up. This wears down on their efficiency, as they need more power than before to operate at the same level. A cared-for system runs at its best, and shares that love right back in lower heating costs.

According to the Department of Energy, old systems have an AFUE rating (the ratio of heat generated compared to the amount of fuel required) of about 56% to 70%. Newer, high-efficiency heating systems can convert over 90% of the energy used into heat using condensed flue gases for less wasted energy.

Choosing the Right Furnace

A new furnace is generally a large investment. To get the best possible new furnace system for your particular needs and assure a comfortable environment for your family, there are many factors that need to be considered:

Type of Furnace

  • Electric furnaces are a suitable alternative where natural gas is not available.
  • Gas furnaces have low operating costs and are the most common.
  • Oil furnaces are another alternative if natural gas isn’t an option for your home.


The minimum Annual Fuel Utilization Efficiency (AFUE) rating for new furnaces is 78 AFUE, which means 78 percent of the electricity, natural gas, oil, or propane used to power the furnace is converted into usable heat. Mid-range furnaces sold today are 80 to 85 AFUE, while the most efficient furnaces are 95 to 98 AFUE.


The most accurate and recommended method of determining the correct furnace size for your home is to have a professional perform a heat loss calculation following ACCA or ASHRAE guidelines. Most heating contractors have the software to perform such a calculation and they can work with a set of plans or perform the calculations on-site.

Consider Your Existing System

It’s important to consider existing systems in your home as well as your future plans. For example, if you’re interested in adding air conditioning, a heat pump might be a better choice than a furnace, depending on your climate. And if your home doesn’t have ductwork, a boiler could prove to be the most economical option.

When it is time to get a new HVAC system, it is best to ask for an estimate or HVAC quote from a contractor to give you an idea of how much it will cost to replace your system.

Things you’ll need to know:

  • How big is your home? (sq. ft)
  • What year was your home built?
  • Where is your current heating system located? (basement, closet, etc.)
