5 Common HVAC Problems (and How to Prevent Them)

March 18, 2025

Your HVAC system is essential for keeping your home comfortable year-round. However, like any other appliance, it requires regular maintenance to function properly. At Eco Air NW, we specialize in HVAC installation and repair, as well as mini-split A/C systems, to ensure your system runs efficiently. Below are five common HVAC problems and how you can prevent them.

1. Dirty or Clogged Air Filters

A dirty air filter restricts airflow, reducing your system’s efficiency and leading to higher energy bills. It can also cause your unit to overwork, leading to premature wear and tear.


Prevention: Check and replace air filters every 1-3 months, especially during peak usage seasons.

2. Refrigerant Leaks

Low refrigerant levels can reduce cooling efficiency and cause your system to work harder. If left unchecked, it can lead to compressor failure, which is a costly repair.


Prevention: Schedule regular HVAC maintenance to check refrigerant levels and identify potential leaks before they become serious.

3. Thermostat Issues

A malfunctioning thermostat can cause inconsistent temperatures or prevent your HVAC system from operating correctly. This could be due to dead batteries, incorrect settings, or a faulty unit.


Prevention: Ensure your thermostat has fresh batteries, is set correctly, and consider upgrading to a programmable or smart thermostat for better energy efficiency.

4. Clogged Drain Lines

Over time, your system’s condensate drain line can become clogged with dirt and debris, leading to water leaks that can cause damage to your home and promote mold growth.


Prevention: Regularly inspect and clean the condensate drain line to ensure proper drainage. If you notice excess moisture or water pooling near your unit, contact a professional.

5. Wear and Tear on Components

As your HVAC system ages, components like belts, motors, and electrical connections can wear down, leading to system failures or inefficiencies.


Prevention: Schedule annual HVAC tune-ups with Eco Air NW to inspect and replace worn components before they lead to costly repairs.
