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.

After 28 years of using a Lennox central heating and air conditioning system, we decided was time to get new systems and we went with Carrier this time, a highly respected brand too backed by GEM Plumbing as a certified provider. Both the sales process and the speed of the installation were incredibly efficient. We spoke with Peter on a Tuesday morning , and by 3:00 p.m. on Friday of same week the installation was complete. We were lucky enough to have Joe Medeiros and Cristar Fig from GEM as our technicians!
Let me tell you, this duo is exceptional! They are very young but possess extensive knowledge and a fantastic attitude. I was truly impressed by their technical work and their courtesy. These two technicians are a great asset to GEM and WE would love them to be recognized! We are very happy at home; the air conditioning system works wonderfully! And We can’t wait to use this coming winter our new furnace too!
Thanks to Peter, Sean, Joe, and Cristar for their amazing job!!
Sincerely
Mary
