HVAC Problems: When to DIY & When to Call the Pros

Dealing with HVAC problems can be a headache for Northern Virginia homeowners, especially when it comes to deciding whether to attempt a DIY fix or call in the professionals. In this blog post, we'll discuss five common HVAC issues and provide guidance on when it's best to tackle the problem yourself and when it's time to call the pros at AirPlus.

1. Dirty or Clogged Filters

One of the most common HVAC problems is dirty or clogged filters. When your filters are dirty, your system has to work harder to circulate air, which can lead to decreased efficiency and higher energy bills.

DIY or Call the Pros? This is usually a simple DIY fix. Regularly check and replace your filters according to the manufacturer's recommendations, usually every 1-3 months. If you're unsure how to do this, consult your system's manual or look for instructions online.

2. Thermostat Issues

Thermostat problems can cause your HVAC system to run inefficiently or not at all. Common issues include incorrect temperature readings, faulty wiring, and dead batteries.

DIY or Call the Pros? If you're experiencing thermostat issues, first check the batteries and ensure the device is set to the correct mode (heating or cooling). If the problem persists, it may be time to upgrade to a programmable or smart thermostat or call in the pros for a more in-depth diagnosis and repair.

3. Strange Noises

Unusual noises coming from your HVAC system can be a sign of a problem. These can include rattling, buzzing, or screeching sounds.

DIY or Call the Pros? In some cases, the issue may be as simple as a loose screw or debris caught in the system. However, if the noise persists or is accompanied by other issues, it's best to call a Northern Virginia HVAC technician to diagnose and fix the problem.

4. Leaking Refrigerant

Refrigerant leaks can cause your air conditioner to lose efficiency and struggle to cool your home. Signs of a refrigerant leak include ice buildup on the evaporator coil, a hissing sound, or reduced cooling performance.

DIY or Call the Pros? Leaking refrigerant is a problem that should be handled by a professional. The Environmental Protection Agency (EPA) requires technicians to have special certification to handle refrigerants, so it's best to leave this job to a trained expert.

5. Electrical Issues

Electrical problems can cause your HVAC system to malfunction or stop working altogether. Common issues include blown fuses, tripped circuit breakers, and damaged wiring.

DIY or Call the Pros? While you can check and reset your circuit breaker or replace a blown fuse yourself, any other electrical issues should be handled by a professional. Working with electricity can be dangerous, so it's best to leave this job to the experts.

If you're unsure whether to tackle a problem yourself or call in the pros, it's always better to err on the side of caution and consult with the Northern Virginia HVAC experts at AirPlus. We're here to help you with all your heating and cooling needs, from routine maintenance to emergency repairs.
