3 HVAC Problems That Are Simple To Fix

Your home's HVAC system keeps you comfortable year-round, but it can also be a source of plenty of headaches. No one likes to get an expensive bill or, even worse, discover that a critical component such as a compressor or heat exchanger is on its way out. Fortunately, most HVAC issues you're likely to face in your home will not be quite so dramatic.

While it's always a good idea to call in a professional if you're unsure what's wrong, these three HVAC issues are so simple that nearly anyone can resolve them.

1. Clogged Filters

Your HVAC filter keeps your home's air clean, but that doesn't mean that the worst outcome from a clogged filter is reduced air quality. As your filter becomes more clogged, it restricts airflow through your home's heating and cooling system. Critical components such as your AC evaporator coils and furnace heat exchange rely on smooth, continuous airflow to function correctly.

As a result, a clogged filter can cause numerous problems, including an overheating furnace or a frozen AC system. The good news is that replacing most filters is as simple as pulling the old one out and installing a new one. If you're noticing unusual problems with your home's HVAC system, checking and replacing the filter is always a great place to start.

2. Incorrect Fan Settings

Nearly all thermostats have a setting that will allow you to adjust how your HVAC fan behaves. You'll typically have options that include "auto," "on," and "off," although some systems may also have a "circulate" mode. The "auto" setting is the correct choice in most cases since this only runs the fan while the system is heating or cooling.

However, many people switch their HVAC fan to "on" during the summer, thinking this will provide more cool air. In reality, this setting causes the blower to operate continuously, preventing the evaporator from draining condensed water away. On hot days, constantly running the fan can drastically increase humidity. If your home feels too humid with your AC on, check your thermostat fan setting.

3. Tripped Breaker

Modern HVAC systems need electricity to operate. Even a natural gas furnace requires electricity for its hot surface igniter, control board, draft blower, and other components. If your HVAC equipment doesn't turn on, you should always start by checking the switches on the units themselves and the breaker. If the breaker is off, switch it back on and see if the system operates as it should.

Even if your system operates fine after switching the breaker back on, remember that a breaker won't trip for no reason. If it happens again, stop using the system and call in a professional for an evaluation. When dealing with electrical issues, it's always better to be safe than sorry.
