Is your current HVAC system too small or too large? Up to 50 percent of heating and cooling systems installed in the U.S. are not sized properly. Knowing how to choose the right size HVAC system will cut your energy costs.

One obvious sign of an undersized HVAC system is an uncomfortable home on the hottest and coldest days of the year. The unit is running continuously, but the house never gets comfortable. On moderate days, the system runs much more than it should. That translates into higher energy bills.
There are also hidden costs. Because the system is running so much, it sustains excessive wear and tear. That leads to more frequent repairs and shortens the life of the equipment.
Oversized HVAC Equipment
Oversized HVAC systems cycle on and off frequently. During the summer, the A/C does not have enough time to remove the excess humidity in the house. That can lead to mold growth. The frequent cycling also causes excessive wear and tear, leading to more repairs and a shorter life.
You are going to also pay more upfront installing an oversized unit.
Getting Properly Sized HVAC Equipment
If you need to replace your current HVAC equipment, keep these things in mind:
- Don't let the contractor do a one-for-one swap based on the current size of the unit. If your current unit is over or under-sized, you do not want to replace it with the same size unit.
- Don't let your HVAC contractor use a rule of thumb (like one ton of capacity for every 500 square feet) for guessing the size of the new equipment.
- Make sure your HVAC contractor in Holliston uses Manual J from the Air Conditioning Contractors of America to calculate the size of your new HVAC equipment. This is a comprehensive method for figuring out the exact load that your home needs based on its size, dimensions, orientation, and features.
