Taking care of your HVAC system is one of the best ways to ensure long-term comfort, energy savings, and reliable performance. While there are a few maintenance tasks you can do yourself, there are others that require professional tools, training, and safety knowledge.
At Van Bremen’s Heat & Air, we believe in empowering homeowners with the right information. Here's a breakdown of 3 HVAC tasks you can DIY—and 5 that you should leave to our experienced technicians.
3 HVAC Tasks You Can Do Yourself
1. Change Your Air Filter
How Often: Every 1–3 monthsA clogged filter restricts airflow, reduces efficiency, and puts unnecessary strain on your system. Swapping it out is simple—just follow the manufacturer’s instructions and make sure to use the right size filter.
Pro Tip: If you have pets, allergies, or live in a dusty area, check filters more often.
2. Clean Around the Outdoor Unit
Why It Matters:Leaves, grass clippings, and debris can block airflow to your condenser unit and cause your system to overheat. Make sure there’s at least 2 feet of clearance on all sides.
DIY Tip: Gently hose off dirt or dust on the fins—but never use a pressure washer.
3. Check and Adjust Your Thermostat
If your home feels too hot or cold, don’t rush to call for service just yet. Check the settings on your thermostat. Is it set to the correct mode (heat or cool)? Are the batteries fresh? A simple reset or adjustment may be all you need.
Bonus: Upgrading to a smart thermostat can improve energy efficiency and humidity control. We can help with installation!
5 HVAC Tasks You *Should Leave to the Pros
1. Electrical Repairs
Modern HVAC systems are loaded with electrical components, from capacitors and contactors to control boards. Attempting to repair or replace these parts yourself is dangerous and can void your warranty.
Call Van Bremen’s if: Your system won’t turn on, is tripping breakers, or is making electrical buzzing noises.
2. Refrigerant Charging or Leak Detection
Refrigerant issues can cause your AC to blow warm air or ice up. But refrigerant is a chemical that must be handled and disposed of properly by a certified technician. DIY refrigerant refills can damage your system—or lead to fines.
Warning Sign: If your system is low on refrigerant, there’s usually a leak that needs to be professionally located and repaired.
3. Deep Coil Cleaning
Over time, dust and grime can build up on your evaporator and condenser coils, reducing system efficiency. While you can gently rinse the outdoor unit fins, full coil cleaning requires special tools and access inside your unit.
We use safe, approved coil cleaners and techniques to avoid damaging sensitive components.
4. Ductwork Inspection and Sealing
Leaky or poorly insulated ducts waste energy and reduce airflow. While you might spot a disconnected duct in an accessible attic, a full duct inspection requires specialized equipment like airflow testers and smoke pens.
Let us help you identify leaks and make sure your air is going where it should—not into the attic or crawlspace.
5. Annual Tune-Ups and Safety Checks
Regular professional maintenance helps catch small issues before they turn into expensive repairs. It also keeps your system running efficiently and safely, especially before the heating or cooling season begins.
Included in our tune-ups: Electrical testing, system calibration, filter checks, thermostat programming, condensate line flushing, and more.
