Professional AC Repair for Wellesley Homes

When your AC fails in a Wellesley home, you need service that understands older construction.

Same-day appointments, 24/7 emergency response, clear pricing. Call GEM today for air conditioning repair services in Wellesley.

We Repair All Types of AC Issues in Wellesley

Colonial estates and renovated antiques present unique challenges. We’ve seen them all.

GEM’s air conditioning repair team handles every type of problem Wellesley homeowners encounter.

Your AC operates continuously but temperatures keep rising. Our air conditioning repair technicians in Wellesley will diagnose whether it’s refrigerant loss, compressor trouble, or restricted airflow and restore cooling quickly.

When your system shuts down before reaching the set temperature, something is forcing early shutoff. GEM’s air conditioning repair specialists in Wellesley will identify the cause and get full cycles running again.

If your bills increased without changes in usage, your AC is compensating for a problem somewhere. Our Wellesley team will find the inefficiency and correct it.

New sounds from your air conditioner indicate something is loose, worn, or failing inside. Our air conditioning repair team in Wellesley will locate the source and repair it before it worsens.

When one level stays comfortable but another won’t cool, airflow or capacity is the issue. GEM’s air conditioning repair technicians in Wellesley will diagnose the imbalance and restore even temperatures.

When your air conditioner won’t power on at all, waiting isn’t practical. GEM provides 24/7 emergency air conditioning repair in Wellesley to restore cooling as quickly as possible.

I wasn’t anticipating a plumbing issue on a Friday before a long weekend but there I was with a busted hot water tank and a very wet floor. I called GEM at 1030am and by 130 Carmelo and Marcelo were at my house. They quickly diagnosed the situation and we scheduled an appointment for Sat am to have the tank replaced. Sat AM they were there earlier than planned and completed the job efficiently and professionally. Very happy with this company !

The tech Franny was awesome. So were the contact people on the phone. Franny cleared the drain lines from our cottage to septic. He also scoped it so we know what issues are needed to address in future. Only downside was the cost. They use a predetermined pricing for job type. Franny was here for 2 hours (though he drove 3 to get to us). The charge was over 1K per hour. Still, they showed up on time, booked it for day after the clog started, and now all is working well. I’d highly recommend them, especially Franny.
