Changing up your floorplan is an increasingly common project. You might want an extra room. Or, maybe that garage would work better as a study. Even expanding an existing room needs a lot of planning and groundwork. Don’t let air conditioning get lost along the way. Keep these three heating considerations in mind when starting to build:
Will the new space have adequate ventilation?
Houses have a lot of invisible ventilation. Brick walls aren’t solid: they have minute gaps in the grout to allow for air flow during contraction and expansion. Every roof is ringed with a series of vents that let air escape from your attic, and that’s not even considering the (at least two) attic fans your house should have closer to the peak of your roof. Make sure your contractor has accounted for air flow in your new space, especially if you have gas appliances or use a furnace.
Can your HVAC handle the new load?
Heating systems are designed around the square footage they have to keep warm. Even knocking down a wall or changing the floor plan without incorporating new area can make your existing HVAC less effective. Have an expert check that your heater can fully heat the new space without impacting its effectiveness throughout the rest of the house.
Who is making the HVAC changes?
General contractors generally aren’t licensed to install, repair, or modify heating and HVAC systems. Double check that your contractor is bringing in expert professionals who are certified to make the changes you need. It might be more expensive upfront, but it will save you a lot in time, money, and stress over the years.
