What Causes Heat Pump Problems?

Several things can impact your system’s performance. Some problems are minor and easy to fix. Others may require more in-depth services, such as heat pump replacement. Our team sheds light on these issues to help you determine the best corrective action.

Dirty Coils Or Clogged Air Filters Can Restrict Airflow

Clogged filters and dirty coils are some of the most common reasons that these systems lose efficiency. When airflow is blocked, your system has to work harder to push air through — which means higher energy bills and faster wear on critical parts. Additionally, these issues can impact indoor air quality if not promptly addressed.

Refrigerant Leaks Can Impact Temperature Control

Refrigerant is essential for your system to cool and heat your home. If the equipment has a leak or low refrigerant levels, it won’t be able to keep up with temperature demands, especially during peak San Marcos heat.

Faulty Reversing Valves Can Prevent Mode Changes

The reversing valve allows your system to switch between heating and cooling. If this part fails, you might find the unit stuck blowing warm or cold air. If your thermostat is reading an incorrect temperature, it’s best to contact Oasis to find the root of the problem.

Electrical Issues Can Disrupt Your System

Many HVAC systems rely on a lot of electrical components to run smoothly. Faulty wiring, loose connections or a malfunctioning thermostat can lead to a range of problems — from short cycling to total system failure. Severe electrical problems may require a replacement to restore indoor comfort.

How San Diego’s Climate Affects Your Heat Pump

San Diego County’s mild winters and long stretches of warm weather mean heat pumps often run year-round. They switch between heating and cooling as temperatures shift, ensuring your space remains comfortable, no matter the season. This frequent use adds up, especially in areas like San Marcos, where inland heat and seasonal dust can strain your system.

Coastal homes may also face corrosion from salt air, while inland neighborhoods like Discovery Hills or Twin Oaks Valley can see more debris buildup around outdoor units. These local conditions make regular maintenance and timely repairs especially important to keep your system running efficiently.
