When to Fix It Yourself & When to Call the Experts: HVAC Edition

As a homeowner, you want your HVAC system running smoothly year-round, but when something goes wrong, how do you know if it’s a DIY fix or time to call the pros? While some minor issues can be handled with a little know-how, others require trained technicians to avoid further damage, higher energy bills, or safety risks.

Let’s break down common HVAC situations and help you decide when to fix it yourself and when to call in the experts.

DIY HVAC Fixes: What You Can Safely Handle

1. Changing the Air Filter

This is the easiest and most important DIY task. A clogged filter can restrict airflow, strain your system, and spike energy bills. We recommend changing it every one to three months, depending on usage and whether you have pets or allergies.

2. Checking the Thermostat

If your HVAC system isn’t turning on or off properly, check the thermostat first. Make sure it’s on the right setting (cool or heat), the batteries aren’t dead, and the temperature is set correctly. Sometimes, a quick adjustment or battery replacement is all that’s needed.

3. Cleaning Around the Outdoor Unit

Leaves, grass, and debris can block airflow around your condenser unit. Keep the area clear within a two-foot radius, and gently rinse the coils with a garden hose (with the unit turned off). Just be careful not to bend the fins.

When to Call Our Team of Experts

Even though DIY fixes can save money, there are times when it’s smarter—and safer—to trust a licensed HVAC technician. Here’s when to pick up the phone:

1. Weak or No Airflow

If your vents are barely blowing or not producing any air, the problem may be a failing blower motor, frozen evaporator coils, or a serious ductwork issue. These aren’t DIY-friendly and should be diagnosed by a professional.

2. Loud, Unusual Noises

Rattling, buzzing, banging, or screeching sounds often indicate loose or broken components, motor problems, or refrigerant issues. Ignoring these sounds can lead to system breakdowns. Don’t guess—get it checked out.

3. Short Cycling or Constant Running

Short cycling (when your system turns on and off frequently) can wear out your equipment and raise your energy bills. This could be caused by a malfunctioning thermostat, overheating parts, or improper system sizing. A technician can pinpoint the cause.

4. Frozen Coils or Leaking Water

If you notice ice on your indoor or outdoor unit or find puddles near your system, shut it off and call for help. Continuing to run the unit could damage your compressor or cause electrical problems.

5. Strange Smells or Burning Odors

Any burnt, musty, or chemical smells coming from your vents need immediate attention. These could indicate mold growth, electrical issues, or refrigerant leaks—all serious issues that require expert intervention.
