Common Furnace Problems

Know What To Do

One thing people love about furnaces is how simple and easy they are.

But that doesn’t mean they’re trouble-free.

If your furnace isn’t working, you may be worried about expensive repairs, or replacement. But you may be able to solve the problem yourself.

Here are some common problems with furnaces, and what to do about them.

My Furnace Won’t Start

This problem may be solved with some detective work by you, so you won’t have to contact your HVAC service technician for a service call.

First, check to see if your thermostat is working properly, is set to at least 5˚ higher than the temperature in your home, and is set to “HEAT.” Then check to see how much propane is in your tank. If you have less than ¼ tank, call us right away to request an emergency propane delivery.

Make sure all the power switches are in the “ON” or “START” position. Check your circuit breaker box and turn the breaker for your furnace back on if the circuit was tripped.

Check your air filter. A clogged air filter can shut down your furnace. If it’s dirty, replace it.
If none of these work, request a no-heat service call from your HVAC service technician.

The Air From My Furnace Is Dry

Very dry air creates all kinds of problems. You can get dry, itchy skin. It can aggravate respiratory conditions. Dry air can damage wood cabinetry, flooring, furniture, and trim. It can also damage art and electronics.

The best solution for this is to install a whole-house humidifier into your home’s heating system. It will give you just the right amount of moisture so you and your family are more comfortable.

My Furnace Is Cycling On Frequently

Is your furnace turning on and off more often than it used to? That can be the sign of several problems, including a faulty thermostat or dirty air filter. Check each and replace if needed. Also remove any obstructions from near your vents. If your furnace is still turning on and off more frequently, contact your HVAC service technician for a service call.

There Are Cold Spots In My Home

There are two likely reasons for that. The first is that your vents are being obstructed, so the heated air isn’t circulating properly, and parts of your home aren’t being warmed. Check each room in your home and look for the vents. Are they covered by curtains? Is furniture or something else placed right in front of them? Move furniture away and tie back the curtains or pin the hems up so they aren’t blocking the vent.

Another reason could be drafts, which usually happen around windows and doors. This can be improved with caulk, weatherstripping, expanding foam, and, for windows, insulated draperies.

If these don’t work, get in touch with your service technician.
