Annual Air Conditioning Service

Regular Cooling System Maintenance to Keep Your Massachusetts or Southern New Hampshire Home Refreshingly Cool

A pre-season cooling tune-up can help prevent unexpected hot summer day breakdowns. Often times a potential problem can be spotted before it becomes a major issue.

Annual maintenance helps ensure that your equipment will operate properly and at peak performance at the time it is most needed. Many manufacturers require annual maintenance to be done to keep factory warranties in place.

Preventive maintenance is one of the smartest things you can do to prolong the life of your equipment. Call Main Stream Mechanical and let one of our expertly trained technicians make sure that your equipment is running safely and efficiently.
