Our AC Repair Services

No two air conditioning problems are exactly alike. That’s why Semper Fi Heating & Cooling takes the time to identify the cause of the issue before recommending a repair. Our technicians service most major brands and use proven repair methods to restore dependable cooling as quickly as possible.

Air Conditioner Diagnostics

Finding the source of the problem is the first step toward an effective repair. Our technicians perform a thorough inspection of your air conditioning system, checking electrical components, refrigerant levels, airflow, and overall system performance to pinpoint the issue accurately.

Refrigerant Leak Repair

Low refrigerant levels can prevent your air conditioner from cooling properly and place unnecessary strain on the compressor. We locate refrigerant leaks, complete the necessary repairs, and recharge your system according to manufacturer specifications.

Thermostat & Electrical Repairs

A faulty thermostat, damaged wiring, or failed electrical component can keep your air conditioner from operating correctly. We diagnose electrical issues safely and replace worn or malfunctioning parts to restore reliable performance.

Blower Motor & Fan Repairs

Your blower motor and fan are responsible for moving cool air throughout your home. If airflow becomes weak or stops altogether, we’ll inspect these components, repair damaged parts when possible, and replace them when necessary to keep conditioned air circulating efficiently.

Frozen Coil & Airflow Repairs

Frozen evaporator coils are often caused by restricted airflow, clogged filters, refrigerant problems, or other underlying issues. Our technicians identify the root cause, correct the problem, and help prevent the issue from returning so your system can cool your home efficiently again.

Isaiah did a great job flushing out my hot water heater. He was personable and professional while pointing out the reasons I needed to consider replacing my 18 yo unit. $49 was a great deal imo. I’d use Semper Fi again. ⭐️⭐️⭐️⭐️⭐️

They answered the phone on a holiday weekend, had a tech onsite in a few hours, brought in a temporary solution for the night and had people replacing the system the next day.

Same day service, technician was out to the house quick and diagnosed the problem. Within a few hours I had 2 technicians show up with all new equipment and started doing a whole system change. They stayed until the job was finished. Victor and Jason were very dedicated to ensuring the job was done correctly. So far a great experience with semper fi!

Brandon and Andrew were wonderful workers. They were extremely caring from the moment they came into my house till they left. They took time to make sure our unit was working at tip top shape and completely explained how my A/C works. They took before and after pictures of the places they worked on and were very proactive with Cleaning. As a senior on a fixed income the price for the tune up was extremely affordable. I cannot express how thankful I am to Brandon and Andrew for their mindfulness and honesty through this appointment. They are truly valued team members. Thank you Semper Fi for putting veterans/ military families first.
