Importance of Proper Replacement Furnace Sizing

At Airtime Heating & Cooling, furnace replacement is among our specialties, particularly during the colder winter. Whether you’re looking to reduce your monthly heating bill, increase your heating capacity or stop spending on the same repair over and over, our pros are on hand to assess your damage and provide you with a cost-effective solution. One of the key factors to consider when installing a new furnace? The size of the unit, which will play a big role in everything from heating capacity to your utility bill. Let’s go over some of the risks you run with an improperly sized system, why you should always consult with professionals here, and the tools and calculations we’ll use to find the right size for you. importance replacement furnace sizing

Issues With Poorly Sized Systems

Just like with air conditioner units, you run into several specific risks when you purchase a furnace that’s either too large or too small. Oversized furnaces will provide too much heat in many cases, making rooms – especially those closest to the furnace itself – far too hot. They’ll also turn on and off too frequently, which will stress the entire HVAC system and result in additional service calls. On the flip side, furnaces that are too small will have to run far too often to keep up with your home’s heating needs. They’ll put a huge stress on your vents and ducts, upping your energy costs in a huge way just to provide the same amount of heat as a properly sized system.

Proper Calculations

It’s generally possible to find basic charts or calculations on the websites of furnace manufacturers, and these can be a good guide when it comes to furnace size. However, you should know that HVAC technicians like ours are trained with much more detailed calculation methods here – for a system that truly fits your home, you should consult with us. We’ll take measurements and inspections in several important areas:
  • Square footage of the home
  • Cubic feet of indoor air space
  • Integrity of home “envelope”
  • Exposure to sunlight
  • Ductwork efficiency
  • Type, quality and amount of insulation
  • R-value and U-value of windows, doors and other air passage elements

Upgrading Models

In many cases, you’ll love your current furnace and its performance, but it will come time to replace it based on age. Many homeowners default to just buying the same size model – but hold on a moment. You might be able to upgrade to a more efficient model that’s smaller but still provides the same benefits for a lower cost. Speak to our HVAC technicians about this next time your furnace is up for replacement rather than just defaulting to the same size.
