Heater & A/C Service in Eugene, Springfield, and Junction City

Heater & A/C Service Near Me

Western Oregon summers can get hot, and our winters are cold and damp. Your heating and air conditioning systems keep you comfortable either way, and they also help keep your windshield clear by removing moisture from the air. That makes a working defroster an important safety feature on foggy mornings.

Over time, A/C systems can lose refrigerant, and components like compressors, blend doors, and blower motors can wear out. Our team can find the cause and get your climate control working again.

Heater & A/C FAQs

Why is my A/C blowing warm air?

The most common cause is low refrigerant from a leak, but it can also be a failing compressor, a clogged cabin filter, a blend door issue, or an electrical fault. We’ll test the system and find out which.

Do I need to recharge my A/C every year?

No. A sealed A/C system shouldn’t lose refrigerant. If yours needs recharging regularly, there’s a leak somewhere, and simply adding more refrigerant is a temporary fix at best.

Why does my A/C smell musty?

Moisture collects on the evaporator and can allow mold and bacteria to grow. A cabin air filter replacement and evaporator cleaning usually take care of it.

Should I run my A/C in winter?

It helps. Running the A/C with the defroster pulls moisture out of the air and clears your windshield faster on foggy mornings. It also keeps the system’s seals lubricated.

How often should the cabin air filter be replaced?

Roughly every 12,000 to 15,000 miles for most vehicles, or more often if you drive dusty roads or have allergies. It’s a small item that makes a noticeable difference in airflow and smell.
