Heating and Air Conditioning questions, answered by experts

There are several common types of HVAC systems that you may have, including split systems, hybrid HVAC, duct-free systems, packaged heating and air, geothermal heating, or even portable units for heating or cooling. If you aren’t sure which type is in your home or are looking to install something different, you should consult an HVAC pro to determine which option is right for your heating and cooling needs.

You need to know the square footage of your home first. Multiply that number by 20, which will get you the BTUs (British Thermal Units) needed to cool your home efficiently. Homes up to 1,000 square feet usually need a 1.5-ton unit; homes 1,000 to 1,200 square feet usually need a 1.75-ton unit, and homes 1,200 to 1,400 square feet usually need a 1.9-ton unit. Talk to a local pro for more specific advice on your home. 

Your AC might not cool after a power outage because of a tripped circuit breaker, blown fuse, or damage to the compressor or capacitor. If you notice your AC not working after a power outage, in most cases, the breaker has tripped or the system has built-in brownout and blackout protection. Reboot the AC by turning it off at the thermostat, resetting the circuit breaker, and waiting 30 minutes to turn the AC on again. 

The $5,000 rule for HVAC systems helps homeowners decide whether to repair or replace an AC or furnace. Take the quote for the HVAC repair cost and multiply that by the age of the HVAC system. If the total is higher than $5,000, it’s more cost-effective to replace the system. If the total is lower than $5,000, consider repairing the system.

If you know how to identify supply and return ducts, you’ll find that only the supply ducts will have dampers. Although your return ducts can have dampers, it’s not common. If you have one return duct that is pulling in too much air, adding a damper to it can help with overall system performance. However, dampers on return ducts are not a necessary addition for most homes.
