Common Air Conditioning Problems We Fix
At Dor-Mar, we have the expertise needed to solve a wide range of air conditioning problems. If your filter is clogged, we’ll replace it quickly and efficiently. We also have EPA-certified technicians available to deal with refrigerant leaks. Refrigerant requires careful handling and disposal, so it’s important to hire a professional like Dor-Mar.
Faulty thermostats are extremely common. You may have a bad thermostat if your AC unit isn’t reaching your set temperature. In some cases, frozen evaporator coils are the reason for poor cooling. This occurs due to low refrigerant levels or restricted airflow. We can also address drainage problems, strange noises, weak airflow, and electrical failures.
Prevent Costly Air Conditioning Repairs
In some cases, it’s possible to avoid AC repair with routine maintenance. Air conditioners contain several components that wear out with regular use. Dor-Mar offers annual AC tune-ups to help you avoid unexpected breakdowns. During a tune-up, we’ll inspect every aspect of your air conditioner. This helps us identify and correct minor issues.
Dor-Mar will also clean the system, check the refrigerant levels, and verify that everything is connected correctly and securely. Finally, we’ll calibrate your thermostat and verify airflow levels. To keep your system running efficiently, we recommend changing your air conditioning filter regularly. Filters can get clogged with dust, pet hair, and other debris.

Our AC Repair Process
Our AC repair process begins when a technician inspects your indoor and outdoor units. They’ll also use diagnostic tools to check your refrigerant levels and system pressure. Next, a technician uses the data they’ve gathered to determine what’s wrong. They’ll explain the problem in simple terms and describe your repair options.
If you decide to proceed with a repair, you’ll have the opportunity to ask questions. We won’t start working on your air conditioner until you’re ready. During the repair process, a technician may clean coils, replace the air filter, or make other changes. You can count on Dor-Mar to be as thorough as possible.
Every repair concludes with a system test to make sure everything is working. We’ll check the temperature output, airflow, and thermostat accuracy. A technician may make a few adjustments during this process. Finally, a technician verifies that everything has been reconnected properly.
