Can you bear to face the summer and winter months without a working home HVAC system? If not, you need to make sure that you keep your system well-maintained and that you’re prepared for potential issues.

There are a few HVAC problems that many homeowners face sooner or later, and knowing about them ahead of time can be helpful. Here are 6 common HVAC problems that you’ll encounter.

1. Air Vent Noise

One of the most common HVAC problems that homeowners face is air vent noise. Homeowners may begin to hear rattling noises, pops, bangs, and other strange sounds coming from vents.

A noisy HVAC unit could be a sign of loosened ductwork connections or ductwork expansion issues that were a result of temperature variance. 

2. Ignition Problems

When it comes to a gas furnace, one of the most common types of problems you may face is ignition problems. These problems can be dangerous and can cause heating issues.

There are many things that can lead to this problem including a gas supply that is blocked or dirty pilot light. You’ll want to get to the bottom of the issue to avoid safety issues and get your furnace working properly again.

3. Water Leaks 

Water leaks are also common with residential HVAC systems. If water has been puddling near heating and cooling units then it likely means that your HVAC has a problem.

This problem could be due to condensate clogging and may lead to bad odors as well as leaking issues. It’s a good idea to call an HVAC professional if you have leaking issues around your HVAC unit.

4. Frozen Evaporator Coils

Another HVAC problem that homeowners commonly face is evaporator coils that become frozen. When ice builds up on the evaporator it can prevent proper home cooling.

Ice may build on the evaporator coil as a result of dirt buildup. Properly cleaning the evaporator can allow it to start working properly again.

5. Dirty Air Filters

A dirty air filter is a very common HVAC problem, but fortunately, can be fixed easily. You’ll simply change the filter in the way that is prescribed by the manufacturer of your system.

If an air filter stays dirty, it can lead to high energy costs and many different HVAC problems, so make sure that you change it as necessary.

6. Thermostat Problems

Thermostat issues and malfunctions can also lead to issues with your home heating and cooling. They can lead to higher energy bills and decreased efficiency.

Thermostat issues could be due to a variety of different things, so it’s important to call a professional. They can check out your thermostat and help find the source of the issue. If you’re in Platte City, MO, you may want to call Snyder’s Heating & Cooling.
