Pre-Season Home Air Conditioning Savings

Summer will be here before you know it. If you’ve been thinking about installing a home air conditioning system, now is the perfect time to do it! Why? Because you’ll beat the spring and summer installation rush and save money by ordering yours before manufacturers’ seasonal price increases.

Choosing the Right Home Air Conditioning System

Home air conditioning systems have come a long way since they were first invented in 1931. Today’s systems are affordable, quiet, efficient, and convenient. And whether you’re seeking to cool just one room or your entire home, there is a state-of-the-art AC system just right for you!

The pros at Main Stream Mechanical will review your options with you, including:


Central AC

A central air conditioning system is ideal for larger homes and residences with multiple rooms or levels. Using your existing air duct system, cool air is quietly and efficiently delivered directly from the unit to each room in your home.


Ductless AC Units

If you don't have an air duct system for central air conditioning, a ductless air conditioning unit might be the right option for you. It provides many of the same benefits as central AC, but without ductwork. These types of cooling systems are quiet, compact, and simple to operate.


High Velocity AC Systems

As its name implies, a high velocity air conditioning system provides outstanding efficiency, performance, and comfort. In fact, our Unico system delivers up to nine tons of air conditioning in the same space as a three-ton traditional unit. The best part? It works in any home configuration—regardless of its age or size. And its small, flexible ducts can be easily routed through your walls, ceilings, and floors without compromising the physical appearance of your home.
