Declan just serviced our home, he was on time, polite and professional! I would recommend this company to anyone looking for a cooling or heating system! My Fujitsu system was installed 11 years ago and always worked like a charm, saving me $$ with the ability to control room cooling or heating vs entire home,
Service was thoroughly performed. The technician was great and knowledgeable.
I had to replace my nest thermostat. I installed it myself, the wiring instructions I followed were not correct. It cycled the system constantly so I asked Major League to come out and look. The technician changed the wiring and everything works fine. Technician fixed the issue and tested the system. Polite and courteous throughout.
Lesson learned get professionals to install equipment!

Thank you, Ivan! We truly appreciate your loyalty over the years and are glad to hear that you find our technicians friendly and efficient.
Very responsive and excellent service. Professional, knowledgeable and quality work.
Major League is the best company. Their guys are polite and knowledgeable. They respond quickly and keep you informed on the condition of service they are preforming. I wouldn’t use any other company for my HVAC system.
Anthony and Declan were excellent, and we really appreciated them making the time to come to our house @7am to get started given how busy they were that day.
As always, Major League never disappoints! Declan did a great job of replacing my capacitor and got my AC system up and running for a reasonable price.
