What size HVAC system do I need?

It’s important to install the right matched system size for your home, depending on a number of factors.

When it comes to your heating and air conditioning system, bigger isn’t always better, and smaller isn’t always more economical.

The Wrong System Size Could Cost You

A system that is too large will cool or heat your house quickly, but you still may not feel comfortable. That’s because it will satisfy the temperature setting on your thermostat before it can adequately remove sufficient moisture from the air-which is what makes you feel so sticky and uncomfortable in summer. What’s more, the stress of short cycling (too many starts and stops) will shorten the life of your equipment and increase your heating and air conditioning bills.

A system that is too small just cannot get the job done. The air conditioner will run constantly in the summer and the furnace will do the same in winter, which may overtax your system and increase your energy consumption.

In most homes across the country, systems are in fact too large. And an oversized system not only makes it more difficult to control your comfort levels, it costs you money, because you’re essentially paying to heat or cool space that isn’t even there. That’s why a properly completed load calculation is so important. We can determine the correct system type and size for your home by doing a room-by-room load calculation. This heat loss/heat gain analysis is the best indicator of the correct system size and takes into consideration such critical factors as:

  • Climate
  • Number of windows and type of window treatments
  • Insulation and duct work
  • Building materials and roof construction
  • Skylights and fireplaces
  • Ceiling heights
  • The number of people in your home
