General HVAC FAQ

How do I determine the size of the unit for my home?

To determine this correctly, you should have a certified HVAC technician come to your home to take accurate measurements, especially if you are looking to replace your old equipment or purchase any new equipment.

Our technicians take a variety of factors into consideration and make accurate and educated recommendations for correctly-sized equipment suitable for your needs. They look at the total square footage of your home, the number and types of windows and doors and rooms, your insulation, and even the number of people living with you to provide an exact calculation.

What does SEER mean?
Some types of equipment have special names for their efficiency ratings of various. As such, AC systems are rated by what is known as a Seasonal Energy Efficiency Rating, or SEER. Like other ratings, the higher the SEER rating, the more efficient the system. Today, any new AC equipment must at least meet a 13.0 SEER rating. Nevertheless, a lot of manufacturers nowadays have equipment that rates as high as 21.0 SEER.
What does HSPF stand for?
Air conditioners that have a heat pump function are rated by what is called a Heating Seasonal Performance Factor. The more efficient units have higher HSPF ratings; it is a ratio of British Thermal Units (or BTU) heat output to watt-hours of energy consumed during the heating season.

Cooling FAQ

Should I cover my outdoor units during the winter?

Covering your outdoor unit during the winter will protect it from falling ice or other issues. Coverings should not be airtight; trash can lid secured down by bungee cords work well. However, if there’s a chance of anyone turning on the air conditioner while it’s covered, don’t do it. Turning on a covered AC could damage your condenser and its internal components. Having said that, outdoor units are designed to withstand the environment year-round and covering them isn’t really necessary.

Can I plant shrubs and/or flowers around my outdoor condensing unit?

Flowers and shrubs are acceptable around your outdoor unit. However, all plant life should be kept a few feet away from the unit to give the system plenty of room for air circulation in and out of the unit.

Without this room for air circulation, the unit might overheat and cause premature problems requiring repairs. Be mindful if you have plants around the unit to remember to trim them and keep everything else out of the way.

What is the difference between a package unit and a split system?
Package units have all the required components, both indoor and outdoor, inside it. A package unit is usually used in commercial properties, apartments, and condominiums. Split systems use an indoor air handler/coil or furnace/coil along with an outdoor condenser unit to provide a fully complete comfort system for the home.
