Replace or Repair


Q: How do I know if it is more cost-efficient to repair my old heating system or replace it?
A: If you’re like many people, the frustration of an equipment breakdown can make it tempting to solve the problem with a quick-fix repair that doesn’t cost you a lot of money. That way you can get on with your busy life in relative comfort. BUT, while a quick fix may be the least expensive solution in the short run, it may not give you the most value in the long run.

It’s a fact of life: Older systems are more likely to break down. That means a bigger chance of emergency service calls and repairs—and paying for them. Worse, a breakdown could mean extensive damage to your home (no heat on a cold winter day can allow your pipes to freeze).

There’s also an ongoing cost factor. Repairing an old system can only restore it to something less than its original level of efficiency. After you’ve recovered from the repair bill and the frustration of a system breakdown, you’ll still be battling high energy bills. What’s more, even if a system doesn’t break down, it loses efficiency as it ages. A 15-year-old system doesn’t operate anywhere near the efficiency it had when it was new!

Plus, when compared with modern, technologically advanced equipment, 15-year-old heating and cooling systems are considered inefficient by today’s standards. The average homeowner can save up to 40% on heating and cooling costs with new high-efficiency equipment.

Here are some rules of thumb to help you decide whether to replace or repair.

Repair your system if:

Don’t wait for an emergency breakdown—like losing your heat in the middle of the night when temperatures are below zero.

Proper design and replacement of heating systems requires thought and planning. Not all models are in stock and immediately available. It is better—and most times less expensive—to schedule equipment installations in the off-season when we have the luxury of time and warm weather.
