Picture this… you head home after a snowy winter hike, and all you want to do is put on some comfy clothes and relax on the couch. But you walk in the door and realize your house is freezing!

You take a quick look at the thermostat and then put your hand up to the vent, only to find that it’s blowing cold air. Guess what – there’s a good chance you’re having HVAC problems.

Before you call a professional HVAC repair company, there are a few things you can do to troubleshoot the problem yourself. Here are four of the most common HVAC problems and some tips to resolve them.

1. Incorrect Thermostat Settings

An incorrect setting on your thermostat is one of the most common HVAC system issues. Luckily, it’s also one of the easiest to fix.

Check to make sure your system is set to heat (or cool, if you’re having problems in the summer) and that no one has adjusted the temperature. If you have more than one thermostat in your home, also check to make sure they’re set close enough so they’re not competing with each other.

2. Dirty Air Filters

To work correctly, your HVAC system needs sufficient airflow. If your air filters are clogged, the air can’t get through like it should. This will prevent the system from heating your house efficiently and can also cause significant problems with your indoor air quality.

It’s always smart to check your air filter before you call an HVAC service company. Homeowners often find that switching to a new one solves their problem.

3. Wrong Size Equipment

If your HVAC system is too small for your space, it will constantly struggle to keep your home warm in the winter and cool in the summer. Going big isn’t always the answer, though.

If your system is too big for the home, it will heat or cool the rooms too quickly. This will cause it to turn on and off frequently, which results in poor temperature and humidity control.

If you’re not sure whether you have the right equipment, consider consulting with a professional.

4. Disconnected Power Supply

There are many different things that can cause power outages, especially in the winter. If you’ve come home to a cold house, check to see if clocks are blinking or there’s any other indication that the system has been without power.

If not, check to see if you have a tripped breaker and that the thermostat is turned on. This may seem simple, but you would be surprised how many people call for professional services only to find out the system isn’t on.
