Frequently Asked Questions - HVAC

The following are questions that buyers interested in air conditioning services may ask about air conditioning and heating systems before they make a purchase. Hopefully this information may dispel any rumors or myths about such purchases.

Q: Why do I need to "match" my condensing unit and indoor coil?

A: Your central air conditioning or heat pump system is a split system. That means it consists of two parts: an indoor unit (coil) and outdoor (condensing) unit. These two parts are specifically designed to work together as a coordinated "team" to provide top performance and maximum efficiency and comfort. Plus, since both components are necessary for a working system, both parts of your existing system were originally installed at the same time - which means they both wear out at the same time. So, if you install a new outdoor unit, be sure to include a new, equally efficient, "matched" indoor unit.

Q: How do heating and cooling systems work?

A: While heat pumps and air conditioners require the use of some different components in your heating and cooling system, they operate on the same basic principles. The job of the heat pump or air conditioner is to transport heat from one point to another. The "vehicle" your system uses to carry the heat is called refrigerant. While it's keeping you cool, your air conditioner or heat pump also works as an effective dehumidifier. During cooler weather, your heat pump reverses the process of the air conditioning system.

Q: How do I compare the performance of heating and cooling products?

A: There are three basic ways you can compare the performance of different air conditioner models and brands: (1) Efficiency - how much energy used to heat or cool your home (2) Sound levels - how much you notice their presence (3) Comfort - how they make you feel. The unit's efficiency is important and indicated by a SEER (Seasonal Energy Efficiency Ratio) rating. The higher the SEER rating, the greater the efficiency and the lower your utility bill. The unit's comfort level is also important and based on how well it keeps your home at a temperature comfortable for you.

Q: What should I look for in a new heat pump or air conditioner?

A: The three most important factors you should evaluate are the air conditioning unit's (1) Quality;(2) Efficiency; and (3) Comfort features. Purchasing a brand name that has a reputation for quality and reliability can save you headaches and extra expense down the road. Cooling efficiency for air conditioners and heat pumps is indicated by a SEER rating, which tells you how efficiently the unit uses electricity. If you purchase a multi-speed or variable-capacity furnace or fan coil with your unit, you will enhance both the comfort and the efficiency of your air conditioning or heat pump system even further.
