What are common causes for service calls?
Most calls we get as the Colorado winters grow closer involve one or more of the following concerns.
1. Continuously-Running Blower
Blower issues can indicate a problem with the limit switch. This usually requires the intervention of a professional service technician.
2. Dirty Air Filters
Dirty or clogged air filters impede airflow, forcing the furnace to work harder. Clogged filters can also damage the limit switch.
3. Electric Ignition or Pilot Control
Thermocouple problems, drafts, and clogs can result in a faulty ignition or unlit pilot.
4. Faulty Thermostat
A malfunctioning thermostat can lead to problems with comfort levels or a fan that doesn’t turn properly.
5. Failure to Heat
Problems with the thermostat setting, gas, pilot light, or power can cause an inability for the furnace to do its primary task.
6. Insufficient Heat
A clogged filter can cause a furnace to produce insufficient heat. Another cause is a unit that’s too small for the space it’s attempting to heat. Our service technician will check your unit and make recommendations as appropriate.
7. Frequent Cycling
Cycling between the “On” and “Off” modes may indicate a clogged filter, improper airflow, or incorrect thermostat setting.
8. Lack of Maintenance
Some homeowners occasionally skip annual furnace inspections and maintenance calls. Whether that’s on purpose or not, doing so can lead to unexpected problems. Routine system tune-ups help prevent breakdowns and keep your system running efficiently.
9. Noisy Furnace
Squeaking, rumbling, or rattling sounds are not standard and typically indicate a mechanical problem, clogged burner, or reduction in airflow.
10. Wear and Tear
Normal wear and tear of a system over time can cause problems with heat control (including overheating) and airflow.
What can I do to reduce the frequency of these problems?
Make it a habit to schedule a routine maintenance checkup on your furnace at the end of each summer or right after Labor Day. A professional tune-up will prepare your system for the upcoming cold season and address problems that can cause more expensive repairs or breakdowns. Enroll in our Preventive Maintenance Program and we’ll automatically schedule regular maintenance visits for this purpose.
Change Air Filters
Many furnace problems are the result of dirty or clogged air filters. Clean or replace your filters monthly while the system is in daily use or every 2-3 months when the system is being used only intermittently.
Check Circuit Breaker and Power Supply
If your thermostat screen goes blank or the furnace stops working, check to see if you’ve tripped a circuit breaker or blown a fuse. Also, make sure that power cords are plugged in.
Check the thermostat battery level if your furnace is not producing heat as expected. Sometimes this problem can be fixed simply by replacing the battery.
If your pilot light keeps going out, you may need only to close a window or door in the room to avoid drafts. If that doesn’t work, give us a call for a check-up.
