Like everything else, heating systems can develop problems. When a heating system starts acting up, many homeowners wonder whether they should repair or replace it.

Repairing a heating system makes sense only when there is a realistic chance of renewing it. Many people believe they can prolong their heating unit’s service life by repairing a failing heating system. In actuality, they are pouring money down the drain.

Here are some factors to consider when deciding whether to repair or replace your heating system from Cozy Home Services, heating repair and installation experts.


With proper care and maintenance, a heating system can last 15-20 years. Heating systems lose efficiency over time and an old heating system will need frequent repairs. If your heating system is on its last legs, consider replacing it.

If you continue using an old heating system, you may end up spending more on repairs and heating bills than on a new system. An old heating system with a cracked heat exchanger can release carbon monoxide into your home.

Inexplicably High Energy Bills

An old or malfunctioning heating system will need to use more energy than normal to meet your home’s heating demands. If you notice a sudden and inexplicable increase in your energy bills, you may need a new, more efficient heating system.

From simple issues such as clogged filters to complex problems such as electrical ignition or pilot control problems, there are several causes of high electricity bills. Before making a decision, have a heater repair expert near you inspect your furnace.

If your heating system means the end of its service life (more than 15 years) and the cost of repairs exceeds half the cost of replacement, opt for a new system as it will save you money in the long run.

Weird Noises

Rattling, popping, or banging noises can indicate serious issues in your unit. A rattling noise from your furnace can indicate something as simple as a loose screw or a severe issue such as a cracked heat exchanger.

If you hear a loud boom every time you switch on your furnace, gas may be building up in your system rather than igniting immediately. A popping noise can mean that your burner is dirty. If you hear unusual noises, notify your contractor as soon as possible.

Frequency of Repairs

If your furnace needs frequent repairs, you may want to replace it with an ENERGY STAR-qualified system. A furnace that is prone to breakdowns can fall apart at any time of day or night, leaving you high and dry without any heat.
