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.

Very fast install of 7-zone mini split system and required panel upgrade. From first call to work completion was less than a week. No quality issues of install and the workers were great. Overall GEM is very expensive, but quality and speed are fantastic.
Just completed AC tune up with Nick R. Courteous and knowledgeable service. Thorough and friendly. Arrived on time and explained his intent. Highly recommend!
Richard F. was the first Gem employee I met. My original appointment was to have the air conditioner yearly service (central air). After opening the side panel Richard showed me the black mold and rust inside the unit. NO ONE had ever opened the side panel during a yearly service appointment. There were years of built up black mold. I will NEVER use the companies I have used in the past. Richard presented 2 options. He was not pushy. He simply presented the information to me and answered all of my questions. Richard is respectful both professionally and personally. We scheduled the appointment for the following day (removal of the old unit and condenser and installation of the new.

The following day Richie and John arrived at 7:45AM. Leo then arrived. They worked from the time they arrived (7:45AM-5:00PM) until they completed the job. They are respectful both professionally and personally. They thoroughly explained all the work they did and gave me information that I did not know previously. Again, we get the a/c serviced yearly and no one had ever explained anything. They cleaned up after completing the work. I mean immaculately.
