There’s nothing quite like Pittsburgh’s sizzling summer afternoons and chilly winter nights. Luckily, the HVAC system works overtime to keep things cozy. But what happens when your AC conks out on a muggy July day?

Before you hit the panic button or dial up a professional HVAC company in Ambridge, PA, know that some air conditioning fixes might just be within your reach. That said, it’s also important to recognize when it’s time to call in the experts.

In this brief article brought to you by Aire Serv, we’ll walk you through a few common AC issues that can be tackled DIY-style and end with tips for knowing when it’s best to leave it to the professionals.

Safety First, Always

Before you grab your tools, remember that safety is non-negotiable. For instance, turn off the power to your AC unit before attempting any repairs. Most units have a disconnect box nearby – use it! And if you’re unsure about what you’re doing, it’s always better to be safe than sorry. When in doubt, call a technician. Aire Serv is always ready to help.

Replacing Dirty Air Filters

Over time, dust and debris build up in the air filter and restrict airflow. This will make your system work harder than it should.

Locate your air filter (it’s usually near the return air duct or the blower compartment), slide it out, and inspect it. If it’s dirty, the replace it with a new one. Filters are inexpensive and widely available at hardware stores.

Troubleshooting Thermostat Troubles

Sometimes the problem isn’t your AC but your thermostat. If your system isn’t turning on, then double-check the thermostat settings to make sure it’s on the right setting. If it’s battery-operated, then replace the batteries. A quick reset might also do the trick.

A Blocked Condenser Unit

The outdoor condenser unit needs plenty of airflow to function properly. It could overheat or suffer performance if surrounded by leaves, grass clippings, or other debris. Use a garden hose to gently clean the condenser coils and remove any obstructions. Be careful not to bend the fins or damage any components!

Addressing Water Leaks

If you notice water pooling around your indoor unit, a clogged condensate drain line might be to blame. This happens when algae or debris blocks the line. Locate the drain line (usually a PVC pipe), and use a wet/dry vacuum to clear the blockage. You can also flush it with a mixture of vinegar and water.

When to Call the Pros

While DIY fixes can save you time and money, some issues require a trained eye – and hands. Here are a few situations where it’s best to call in a qualified HVAC technician:

  • Refrigerant Issues: If your AC isn’t cooling and you suspect a refrigerant leak, don’t attempt to fix it yourself. Handling refrigerants requires specialized training and certification.
  • Electrical Problems: Buzzing noises, frequent breaker trips, or issues with wiring are best left to professionals to avoid safety hazards.
  • Compressor or Motor Failures: Replacing or repairing these components requires in-depth knowledge and specialized tools.
  • Persistent Problems: It’s better to not push your luck.
