If you want to keep your air conditioning unit running efficiently, make sure you replace or clean the air filter once a month. Check the owner's manual on the a/c for instructions on how to clean the filter. Never run the unit when the filter is removed and let the filter dry before reinstallling it.
One of the most important things to consider when purchasing a new heating and cooling system is the manufacturer's warranty. Units come with a variety of warranties. Choose one with a long warranty for maximum long term savings. Generally, it is advised that homeowners should purchase the extended warranty if one is offered.
Before you hire anyone to do any work on your HVAC, be sure to get a written estimate which has itemized costs listed on it. This will ensure that comparing one contractor to another will be simple as you can see what one offers that another doesn't, or what price they're charging for the same items.
If your evaporator coil, found inside your home, becomes dirty, your unit will lose efficiency. Just pop off the front panel of the furnace and check to see that the coil is dry. Using a brush attachment on a vacuum, gently clean the coil of any dust or other debris.
