As winter draws near and temperatures drop, it’s time to make sure your heating system is ready to keep your home warm and cozy. It’s important to look out for hints that your heater needs repairs to make it through the cold months. Here are five warning signs that it's time to call your local HVAC contractor.

5 Indications It's Time for Heating Repairs

1. Burnt Smells

Your heater might burn off a bit of dust buildup when you turn it on after not using it for a while, which can cause it to emit an odor. If a burning smell lingers for a long time, though, this may indicate that some parts of your system are damaged.

2. Clanking Noises

Expansion and contraction of the metal parts in your heater may cause it to make some noise when it kicks on. However, loud screeching noises mean your technician must check for loose parts. Banging sounds may also point to issues with the blower assembly—it could be wobbly or out of alignment.

3. Cold or Extremely Warm Areas

If the heat isn't reaching some areas of your home—or if specific spaces are too warm—you may have a thermostat malfunction or an issue with the heat exchanger. Check your ducts first to see if they’re open before calling to have your heater checked out by a professional.

4. Higher Utility Bills

Your heater's efficiency decreases as it ages. Over time, your system will be working harder to keep your home comfortably warm, and this can drive up your energy costs. If you notice your utility bills have been going up, ask your technician if your heater needs repairs or if it's time to get a replacement—particularly if you’re approaching the 15-year life span of the average furnace.

5. Unpleasant Symptoms

If you’re having unexplained headaches, nausea, and burning eyes, there might be a carbon monoxide leak in your heater, which may be due to improper installation or maintenance. This is an odorless gas that presents a serious danger. Install a CO detector in your home or contact a professional immediately to avoid carbon monoxide poisoning.
