7 Common Heating Issues and How to Fix Them

November 21, 2019

The heating system of your Shenandoah Valley home is an essential part of your comfort during the colder months of the year. Unfortunately, there are many problems your heating system can face that get in the way of a warm and cozy home. Here’s are a few common HVAC issues you may experience and what you can do to fix them.

1. My Heating is Blowing Cold Air

Lack of Fuel

If your heating system’s fuel supply—whether gas, oil, or electricity—is running low or isn’t able to power your system, it can affect performance. Make sure you have plenty of fuel left!

Leaky Ductwork

Typical duct systems have air leaks that lose 25–40% of created heating energy. Schedule ductwork repair to seal up leaks and holes so your hot air can reach its final destination.

2. My Heating Won’t Turn On

Pilot Light Issue

Older furnaces use pilot lights to ignite fuel. These lights can accidentally go out from sudden drafts, or there could be an issue with your gas valve.

Ignition System Failure

Newer heating systems skip traditional pilot lights for electronic ignition system with flame sensors that are prone to breaking or clogging up.

3. My Heating Won’t Turn Off

Broken Thermostat

Not all heating problems are issues with your furnace or boiler. Your thermostat might not be set correctly, or it could be broken or malfunctioning.

Blower Motor Issues

If you can’t get your heating to turn off, you could have a broken blower motor. Schedule a heating repair call with your local HVAC contractor, like Excel.

4. My Heating System Doesn’t Heat My Whole House

Dirty Filters

As dust and particulates are caught by your filter and accumulate, they block air flow, preventing conditioned air from making its way to all the rooms in your home.

Inadequate Ductwork

If your ductwork’s poorly designed, too many sharp turns will make it difficult for air to travel the entire way through your system. Have your ductwork evaluated.

5. My Heating Is Repeatedly Turning On and Off

Thermostat Placement

If your thermostat’s sensor is placed too close to a vent, your heating will be tricked into short cycling, which puts a lot of wear and tear on your system and requires more repair calls.

Oversized Unit

If your heating system isn’t properly sized for your home, it could be too powerful. Furnaces are most efficient when they’re on for at least 15 minutes at a time.

6. My Heating Is Making Loud Noises

Slipped or Frayed Blower Belt

A squealing or high-pitched sound coming from your heating system is a good indication that your blower belt is on its way out.

Worn or Broken Motor or Fan Parts

Is your heating making a clunking or rattling sound? There could be a worn or broken part in your motor or fan that should be replaced.

7. My Heating Bills Are Too High!

Schedule HVAC Service or Repair

Even if your heating works, it could be running very inefficiently, creating high heating bills. Schedule regular heating maintenance and benefit more from your HVAC system.

Upgrade to New Heating System

The older your heating system, the more you stand to benefit (and save money) with an upgrade. New high efficiency heating will dramatically reduce your energy bills and increase home comfort.
