How to Know When Its Time for a Furnace Repair Posted February 16, 2018 When it’s chilly in Lexington you depend on your furnace to keep you comfortable. If it’s been some time since your system had maintenance, you might have a furnace repair soon in your future. Even if your system seems to be working well, you may need to clean or replace your air filter. A dirty air filter can stop air flow, hurt your furnace’s efficiency and affect the limit switch that controls furnace operation.There are quite a few reasons you could have to have a furnace repair. The more promptly you can call for a furnace repair, the better. If you see any of the following evidence, call in an expert, like Kelley Mechanical.1. Your furnace is making a lot of noise. You may have a problem if your furnace is running loudly or making noises you haven’t heard before. 2. Your blower isn’t operating correctly. Is it running for enough time? Is it running endlessly? Does the air flow seem weak? You might have an issue with your air filter or furnace blower. 3. Your home isn’t heating up enough. Have you increased the temperature again and again but don’t feel like the temperature is what it should be? This could suggest a few different problems. It could be a problem with your thermostat. It may be a problem with your gas source or pilot light. It could even be that your furnace isn’t large enough for your house. 4. Your monthly bill keeps increasing. Your usage isn’t changing but your bill keeps climbing. This could indicate several different problems. Your HVAC professional will help find out what’s going amiss. 5. You smell gas.
