When Should I Get My Heating System Replaced or Repaired?

“So, when should I really get my heating system replaced or repaired by a professional?” This has been one of the important questions many homeowners ask, especially DIYers who think that repairing or replacing their heating system is as easy as it looks.

Your heating system, whether it’s a furnace or a heat pump, is an essential component of your home that keeps you warm and comfortable throughout the cold chilly months. When this system malfunctions, there are some electrical wirings, water leaks, and other aspects you need to look at first. Fortunately, by looking out for a few warning signs, you can detect a faulty heating system before it fails.

7 Common Signs You Need Heating System Replacement or Repair

Most furnaces, boilers, and heat pumps can last for up to 15 years depending on how they are maintained. Regular maintenance allows heating systems to last even longer. But if your heating system is getting close to the end of its lifespan, there are telltale signs that it needs to be replaced soon.

The following are the most typical warning signs homeowners should watch out for when their heating system ages:

  1. High energy costs
  2. Humidity problems
  3. Increased allergens
  4. Uneven heat distribution
  5. Loud noises
  6. Short cycle
  7. Frequent repairs

These may indicate that your system isn’t operating as effectively as it should be. Another hint that it’s time to replace or repair your heating unit is if you’ve had to call the repair team more times than usual.

Simple Tips to Check Your Heating System

When your heating unit begins to show inefficiency, it’s important to decide if replacement or repair is the best course of action. The decision can be difficult because installing a new heating system might cost a fortune, but it can make more total sense compared to spending money on frequent repairs.

To accurately determine whether it’s better to replace or repair your system, you should call a professional HVAC team to evaluate the degree of the damage.

  • Run a duct-leakage test to evaluate your condenser and blower unit. 
  • Run a blower door test to find out how much air is leaking out of the house.
  • Check out your home’s insulation by examining your home’s exterior, attic, floors, and walls to look for any holes or cracks that could be letting hot air out.
  • Call a professional HVAC technician to adjust the insulation or seal any holes to prevent any damage
  • Make sure any furniture is not blocking any heat flowing around the house.
  • If you have baseboard heaters or boilers, ensure the entire space is effectively heating by making sure air channels are blowing hot air
  • Check your furnace if there is any rust, crack, or corrosion.
  • Turn on the thermostat to get the temperature you want and feel the hot temperature across rooms.
