The winter months can put tremendous stress on your furnace and home HVAC system. After all, that’s when your furnace may be called upon to operate almost continuously to provide comforting warmth in your home despite the plummeting temperatures outside. With that increased workload comes an increased opportunity for system failure, and a breakdown of your HVAC system in the winter can result in great discomfort until your HVAC company of choice comes to the rescue to repair your system.

Though your HVAC in Gainesville, GA, may operate flawlessly for years on end without any problems, a breakdown in the winter is unpleasant. While there are some aspects of HVAC maintenance that are outside of the abilities of the average homeowner, there are a few simple things anyone can do to keep the HVAC system running throughout the winter. Keep reading to learn about some of the most common HVAC issues that arise during the winter and what can be done to remedy them.

Dirty Filter

There are few maintenance tasks that are simpler than changing the filter on your HVAC system. Likewise, there are few maintenance tasks that are more important to the overall health and preventive maintenance of your system. Running your furnace and HVAC system with a dirty, clogged filter can not only impact performance and reduce efficiency, but it can also damage your system. Failure to change the filter in a timely manner is one of the leading causes of winter HVAC problems, so make sure to change your filter at regular manufacturer-specified intervals.

Uneven Heating

Uneven heating usually isn’t traced back to the furnace or heat pump but is rather a function of improper insulation or leaking ducts. In both instances, already-warmed air can escape from interior spaces, which wastes energy and makes it more difficult for your heating system to maintain the set temperature. Conversely, leaks and bad ducts can allow cold air to be drawn into the system, compounding the problem further. If some rooms in the home are colder than others, look for drafts and have an HVAC professional inspect your ducts for leakage.

Thermostat Malfunction

Though thermostats don’t necessarily fail at a greater rate in the winter than at other times of the year, this simple device can be a common cause of HVAC issues year-round. Your thermostat is the nerve center of your HVAC system, as it tells your furnace when it’s time to turn off and on to maintain the desired temperature. Though modern thermostats are more complex than their passive predecessors, they still represent simple technology that can fail at times due to electrical malfunctions. If your HVAC system begins acting up at any time of the year, one of the first things to check is your thermostat.

Bad Pilot

The pilot light in your furnace is an important component because it provides the flame that lights the fuel your system burns to generate heat. Some pilots are continuously lit, while others are electronic and only spark when the furnace activates and lights. When the pilot becomes weak, it can prevent the furnace from lighting. That means that no fuel can be burned, and no heat can be generated. If the flame sensor in your pilot becomes dirty or damaged, your pilot won’t burn brightly if it burns at all. In some cases, the pilot can simply be cleaned. However, in some cases it must be replaced by a professional.
