Common Winter HVAC Problems for Homeowners

This blog is posted by Trophy AC in San Antonio

You don’t want to experience any problems with your HVAC system during winter, but unfortunately, due to the harsher weather conditions, it’s the time of year when most people experience problems. You can prevent most issues that arise by doing a routine check and maintenance. It’s important to prep your house before winter to avoid any major problems.

Below you will find the most common Air Conditioning problems  homeowners experience during winter, and what you can do about them.

Air Filters

When your air filters are dirty, this will restrict the air flow, meaning that your HVAC unit needs to work harder to distribute heat and air throughout your house. Restricted air flow increases your electricity bills, and may shorten the lifespan of your unit. To avoid this from happening, we recommend checking your filters at least once a month and replacing any dirty filters. Air Filter


If you feel that the airflow is restricted, or a room or floor in your house is colder than other areas, most likely it’s caused by airflow restriction. First, you need to check to see if you have blocked any vents with furniture, boxes or another object. You can also take a look and confirm that all pipes are working and are joined to the air supply vents.
Other issues that may be causing an airflow restriction are blocked fans, obstructed vents, dirty ducts or problems with the furnace motor or filters.
The thermostat is what keeps your home warm during the winter, so it’s a vital part of your heating system. If your furnace appears not to be working, it could mean a broken thermostat. If you are experiencing this issue, try to turn the thermostat on and then off, make sure the batteries are still working and the device is clean of dust buildup.
If that doesn’t work, you might have a broken furnace. If your home has a gas furnace, a likely culprit is that the pilot light has gone out. You can either relight it yourself or call a professional to do so.

Heat Loss

Cold weather can ravage your heat pump, so the heat set on your thermostat fluctuates and you can’t seem to warm up your house no matter how high you’ve set the temperature. If you have an outside heat pump, check and remove any frost buildup.
Other causes of heat loss can be compressor problems, non-functioning pilot light or a leak in one of the ducts, making it easier for cold air to come inside.

Frozen pipes

If your pipes aren’t properly insulated, they are more prone to freeze during the winter. If the pipes freeze, your HVAC system will fail, as the hot water heaters and radiators won’t work without the water running through the pipes.Here in the South this my not be a problem, since our system are configured differently.
Another problem is that the pipes may burst. The freezing temperatures turn the water into ice and therefore expand, bursting the pipes. If this happens, you need to call a licensed plumber to fix the issue. To prevent this from happening, make sure that you insulate your pipes before winter.
The easiest way to prevent problems is to have someone inspect your HVAC system once or twice a year. They can help spot any issues and make sure you stay warm during winter.
