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.

Responsive and committed… our needs are met and the work is professional. As good as it comes… note: I’m writing this in a cool, comfortable setting now. 😁
I am very pleased with ALex's service. He is knowledgeable and polite.
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.
Can’t say enough good things about Gem Plumbing and Thomas in particular. I easily got a came day appointment, Thomas the tech was here in the agreed upon window, provided 2 alternative estimates and once we selected, he completed the job right away – no need to make another appointment and come back another day. Great work, and even better service!
Fast and knowledgeable service technicians.
William and Mark were excellent! They explained everything that they were doing and included us through the whole process. Would recommend them highly.
Very prompt and professional service!
The service provided by Mark and his partner was incredible. They took the time to explain all details of the situation and even helped make a call to a remediation company. They cleaned up after themselves and were very easy to discuss the repair process with.
Always a pleasure, professional expert service. Solving any problem simple or difficult!
Came even late at night to make sure we had working air conditioning
The team that installed the unit (Luis Herrera Mezquita Et al) was very professional and explained things thoroughly. I would highly recommend them.
