We Repair All Types of AC Issues in East Dennis

Coastal conditions create unique challenges for air conditioners, and our technicians know how to solve them.

GEM’s air conditioning repair team handles the full range of issues East Dennis homeowners face.

Your AC runs but the air coming out isn’t cold. Our air conditioning repair technicians in East Dennis will determine whether low refrigerant, compressor issues, or airflow restrictions are preventing proper cooling and restore cold air to your home.

Electrical humming or buzzing sounds often signal failing capacitors, contactor problems, or loose wiring. GEM’s air conditioning repair specialists in East Dennis will diagnose the electrical issue and repair it before components fail completely.

Ice buildup on your indoor coils prevents cooling and can damage your compressor. Our East Dennis team will identify whether restricted airflow, refrigerant problems, or other issues are causing the freeze and fix them properly.

When your air conditioner won’t respond to the thermostat, something has failed. GEM’s air conditioning repair technicians in East Dennis will trace the problem through electrical connections, controls, and components to get your system running again.

If some rooms stay comfortable while others remain warm, your system has a distribution or capacity issue. Our air conditioning repair team in East Dennis will diagnose whether ductwork problems, zoning failures, or equipment issues are causing uneven temperatures.

When you hear the outdoor unit running but your home isn’t getting cooler, the compressor or refrigerant system may have failed. GEM provides expert air conditioning repair in East Dennis to diagnose and fix these complex issues quickly.

The technician arrived. He came in and diagnosed the problem with my ductless system. He was able to get my system functioning, even though he didn’t have the pot needed to be replaced so temporarily we can run the system as it is he did he did his job by diagnosing the issue and doing a temporary fix?
I called GEM for a weekend, short notice pipe repair, and everyone was great from Hendry who I spoke to on the phone, to the two technicians Alec and Danny. They worked quickly, communicated clearly, and worked with me to come up with a solution I was happy with the price and result of. I would definitely call them in the future when things pop up.
