Does My HVAC System Need to Be Upgraded to Support My Home Addition?
Congratulations on your home addition! It’s a great feeling to be a homeowner, and it’s an even better feeling to be able to expand your home. However, all good things come with a flip side. With more square footage in your home, you’ll be faced with the decision to upgrade your HVAC or not.
You definitely want to make sure your HVAC system is the right size to properly heat and cool your newly expanded space. But at the same time, you don’t want to be spending money on something that isn’t necessary. QDI is here to help with a guide to knowing whether your unit is still the proper size for your home.
How to Tell if Your HVAC Unit is Now Too Small
There are a lot of factors that go into determining the right size HVAC unit for your home, including square footage, number of windows, ceiling height and even the amount of shade your house gets house gets! Therefore, it’s important to have an HVAC professional assess your heating and cooling needs before recommending the right size system.
However, you can refer to an AC sizing graph to get a general idea of the unit size your home needs. Looking at the chart, you can see that most of Pennsylvania is in Climate Zone 4, where you can generally assume a 1,500 sq. ft. home would require a 2.5 ton HVAC unit. If your home addition has increased your home’s square footage from 1,500 to 2,000, you will need to upgrade to 3 ton unit.
There are also several environmental signs that your home is now too large for your
HVAC system to effectively heat and cool it. These signs include:
- Higher Electric Bills – Did you get a new appliance or start using one more heavily? If the answer is no, you might want to look into the size of your HVAC unit.
- Home Won’t Heat or Cool – Your home might never reach the temperature you need it to be if your unit is too small.
- Long Cycles – Your unit shouldn’t run for most of the day. The cycles should ideally be under 30 minutes.
If you suspect your HVAC unit is no longer the ideal size to heat and cool your home, always give QDI a call at 610-948-9505. We’ll evaluate your home’s comfort needs and make an honest recommendation on whether or not you need an HVAC replacement.
