Proper Installation is Key to HVAC Performance and Energy Savings

Did you know that nearly half of all heating and cooling systems are not properly installed? And failing to correctly install a unit can reduce its operating efficiency to as much as 30 percent! That’s a lot of wasted energy and a lot of wasted money. To get the most out of your system, you should have it installed by a certified HVAC technician and here’s why:

Performance and Energy Savings

When it comes to your HVAC installation, size matters. A lot. A unit that's too small won't heat or cool your home properly, and a unit that's too large will cause you to spend more than you should on energy costs. When you work with the experienced professionals at Main Stream Mechanical, you can be confident your system will be sized to heat and cool your home evenly, without wasting energy.

Longer System Lifespan

Proper installation is essential to the immediate and long-term performance of your heating and cooling systems. When your heating and cooling systems are installed correctly, they will undergo less strain every time they cycle. Less strain translates into less wasted energy and more savings for you. It also prevents unnecessary wear and tear on your system, increasing its overall lifespan and your return on investment.

Warranty Requirements

Many HVAC warranties become void if not installed by a certified technician. When you work with the certified professionals at Main Stream Mechanical, you will ensure your family’s long-term comfort, and protect your investment.

Ease of Installation

After helping you select the right unit for your home, an experienced HVAC technician can replace your old system and install a new one with ease. Heating and cooling technicians are armed with the latest information about inspections, permits, licenses and codes, and possess the right training to know what needs to be done and how to do it safely. Trusting your HVAC installation to the experienced professionals at Main Stream Mechanical saves you from the headaches and stress of removing old equipment and installing a new one.
