Possible Problems With Your AC And Heater In Highland, CA, And Our Solutions
If you’re having problems with your AC or heater in Highland, CA, there are a few things that could be causing the issue. Here are some of the most common problems we see and our solutions:
- Dirty Air Filter: A dirty air filter is one of the most common issues we find. A clogged air filter can cause your unit to work harder than it needs to and can lead to premature wear and tear. We recommend changing your air filter every 1-3 months, depending on the type of filter you have.
- Thermostat Problems: If your unit isn’t cooling or heating properly, it could be an issue with your thermostat. We can look at it and determine if it needs to be repaired or replaced.
- Refrigerant leak: A refrigerant leak can cause your unit to stop cooling properly. If we notice a leak, we’ll repair it and recharge your unit with the proper amount of refrigerant.
- Fan Problems: The fans in your AC unit are responsible for circulating the air. If one of the fans isn’t working properly, it can cause your unit to overheat and eventually break down. We can diagnose and repair fan issues quickly and efficiently.
- Electrical Issues: Electrical issues are often to blame for AC and heater problems. If there’s an issue with the wiring, it can cause your unit to malfunction. We have highly skilled electricians on our team who can take care of any electrical issues you may have.
