HOW TO SIZE YOUR AIR CONDITIONER OR HEATER

Get ready, friends … I’m about to utter two words that most homeowners don’t want to hear: HVAC replacement. You hate to admit it, but it seems your air conditioner is nearing the end and after a few years of coaxing it along, you know it is time to replace it. Of course, this is a major expense and requires quite a bit of planning, both financially and logistically. 

Getting Started With Your Air Conditioning Replacement

A good place to start is by giving your friends here at Masters Heating & Cooling a call. Our HVAC professionals have helped our customers in the Fort Wayne, Decatur, Angola, Indianapolis, Greenwood and Mishawaka, IN areas with air conditioner and heater replacement since 1980 and we stand ready to help guide you through the process. 

One of the first things that needs to be done is determining the size of a replacement system. This is crucial because an improperly sized system can lead to inefficient operation and dehumidification issues and even a shortened lifespan of the equipment. Several factors impact the sizing of a new system, including the size of your home, the climate and environment your home is in and your heating and cooling preferences.

Here are a few tips that should help you and your HVAC contractor arrive at the perfect system tonnage for your home:

Square Footage

This needs to be calculated for each room by multiplying length x width, then combine them all together. 

BTUs

The unit commonly used to measure energy consumed when heating and cooling is the British Thermal Unit, or BTU. Roughly 25 BTUs is required to climate control a square foot of space in your home, so multiply the number of square feet in your home by 25 to get the total BTU measurement. If your home has high ceilings, add an additional 25 percent to the BTU total.

Manual J

This is a load calculation system designed by the Air Conditioning Contractors of America (ACCA). It uses all of the above factors and many more, such as which direction the home faces, insulation amounts and placements, window types and ages, etc. Manual J provides professional with the most information to arrive at the proper size calculation.

So, once the proper system size has been determined, you can begin to explore the options and price ranges available to you. Masters offers a full line of Carrier equipment, and we are happy to announce the Carrier fall promotion. Some new equipment purchases can qualify for up to $1,650 in rebates or special financing available for up to 72 months with approved credit. Also, another factor to add into the replacement equation is the impending Jan. 1, 2020 ban of R-22 refrigerant. If your system is 10 years or older, it likely uses R22 and recharging/repairing it will become more problematic (and expensive). Newer systems use the more environmentally-friendly R-410a refrigerant.
