Proper System Sizing
Choosing the Right AC & Heating System for Your Leesburg Home
How do I ensure that my air conditioner/heat pump is properly sized for my home?
If you live in Leesburg, or in nearby areas such as Ocala, Fruitland Park and The Villages, you know that it can be a challenge to stay comfortable year round. Your HVAC system must be properly sized to ensure your comfort. A heat pump is simply an air conditioner that cools in the summer and heats in the winter. It reverses the flow of refrigerant in the heating mode. When we discuss sizing a heat pump, we are really referring to the heat pump’s air conditioning side. The sizing technique is identical for a heat pump and air conditioner. When it comes time to replace your existing heat pump system, most Central Florida air conditioning and heating contractors will use your existing system size as the primary guide in selecting a replacement. Thermocool offers you 25 years of experience which allows us to perfectly match an air conditioner to the size of your home. Let’s review the steps necessary to properly select your air conditioner/heat pump.
Sizing the Unit
Air conditioning size is expressed either in tonnage or BTU per hour (BTU/h). One nominal ton equals 12,000 BTU per hour.
An oversized air conditioner consumes more energy because it requires more electricity to run a bigger unit. An oversized air conditioner doesn’t lower humidity effectively. That’s because it cools the air so quickly that it cycles off before it has a chance to circulate the proper volume of air through the system to remove the moisture that makes us uncomfortable.
Once the sizing requirements for the cooling side of your heat pump system are determined, then we need to select the proper supplemental heating element that is included with all of our heat pumps. If you are replacing an existing heat pump system, simply locate your main breaker panel and identify the indoor heating unit breaker. Look for a number where you grasp the breaker.
