Maintaining home appliances is an inevitable part of every homeowner’s life. And nowhere is that more important than keeping your heating and cooling system in good repair. Of course, there will come a day when something will need replacement or repair. To stay ahead of the game, here are some of the more common problems you’re likely to encounter—and some tips on what you can do to troubleshoot or prevent problems before they start.
1. Dirty Air Filters
One of the most common causes of furnace inefficiency is dirty air filters. Adequate airflow through your system is essential for it to work effectively and efficiently. If that airflow is obstructed, it will lead to poorer performance and poorer indoor air quality. If severe enough, it can even shut down your system. Luckily, this is one of the easiest—and cheapest—problems to solve. We advise you check your air filters monthly and replace them whenever they’re dirty—and it’s a good idea to keep a couple of spare filters on hand.
Estimated replacement costs: Depending on the size and type of filter your furnace uses, replacement filters range from about $10.00 - $30.00.
2. Failing Thermostat
If your thermostat is not operating correctly, it can lead to problems with your furnace fan, not to mention your family’s comfort levels. This is another problem that can often be solved by some simple DIY steps:
- First, make sure the thermostat is set to the right heating mode.
- Double check the batteries.
- Make sure the target temperature is set correctly.
Estimated repair or replacement costs: Repair costs will depend on time and materials, but you can probably expect between $150.00 - $300.00. Replacement may not be that much more, so you’ll want to discuss with your HVAC pro to determine what’s best for your situation.
3. Electronic Ignition and Pilot Control Problems
If your ignition or pilot controls are damaged or failing, you’ll definitely feel it in lack of heat! While you can check out the condition of your pilot light, resolving ignition and pilot issues are jobs for your HVAC professional. Warning signs
- Yellow, orange, red, or purple flame
- Flickering or sputtering
Estimated repair costs: These will vary depending on what needs to be repaired or replaced. Best to ask your HVAC pro for an estimate.
4. Furnace Turns On and Off Frequently
If your furnace seems to be short cycling, there can be several causes. The first is a dirty or clogged air filter, so start by checking and replacing your filters. Next, check your thermostat settings to make sure they’re where you need them. If you’re still having problems, it’s time to call in the pros.
Estimated repair costs: These will also vary significantly, depending on what your HAVC pro finds needs repair or replacement.
In addition to DIY maintenance and inspection, it’s a good idea to establish a relationship with a reliable HVAC professional and have your system inspected every year. To find a pro in your area, check out our convenient dealer locator.
