Home Maintenance & Efficient AC Performance for Air Conditioner Columbus, Ohio

Your Home Air Conditioner Maintenance

Home air conditioner maintenance will not only help in lowering your energy bill, but will also extend the life of your AC unit. It will also save you from costly repairs with just more diligent care of your AC. Before doing any preventive maintenance, remember to shut off electrical supply to your unit. This will ensure safety when working around the air conditioner’s moving parts.

Air Conditioner Filters

Filters Home Air Conditioner MaintenanceYou should change filters, or clean reusable filters, at least twice a year.  Ideally, this should be once before the cooling season begins and then before the heating season as well. Having dirty filters make your AC unit work harder since this reduces air flow and thus lower its efficiency.  If your location is in a dusty, populated area, you may need to change or clean your filter more often. A regular, monthly inspection of your AC’s filters will give you an idea whether you need cleaning or replacement twice a year or every two months. See a related article in preventative maintenance.

Condenser and Evaporator Coils

The filters help prevent dust, dirt, and debris from getting into your AC unit.  However, your AC’s condenser and evaporator coils will still gather dust over months and years of service.  The outdoor condenser unit collects dust and debris because a central fan sucks air from around it. This pulls dust all sorts of debris such as dead grass, dead leaves, and those floating “cotton” from dandelions and cottonwood trees.

With all these blocking the air flow into your unit, it lowers your AC’s cooling efficiency.  You can further help your unit by cleaning debris around the condenser and cutting foliage by at least 2 feet to allow enough air circulation around the condenser. Keeping the coils clean will help in the cooling efficiency and years of service of your AC.

Coil Fins

The coil fins are the fine metallic blades on the coils. These are fragile and can bend easily, and thus block air flow.  In such a case, there is a tool easily available in hardware stores called the “fin comb” which will straighten them back to nearly original condition.

Regular Check Up of Your AC Professional

Other than the ones mentioned above, there are some tasks that only your AC professional can do. Checking the refrigerant level is one.  Regular home air conditioner maintenance by your licensed AC technician will help in maintaining the efficiency and prolonging the years of service of your unit.



What You Need to Know About Central Air Conditioning

central air conditioningIs this summer heatwave melting you into a puddle on the ground? A lot of people can make it through the warm,  Midwest seasons using only window or portable A/C units. Some get by with just fans. If those aren’t enough to make you comfortable, it might be time to consider having central air conditioning installed.

How Central Air Conditioning Works

Central A/C allows cool air to flow through a system of supply and return ducts. The supply registers and ducts transmit cooled air from the A/C unit throughout your home. As the cooled air circulates in your home, it becomes warmer and flows back to the central A/C via registers and return ducts. This system is one of the most common and efficient ways to cool your home.

If you plan to have a central air conditioning unit installed, the size of your home will determine the size of the unit you’ll need. It is also essential to have the correct size duct work so that the cooling needs of every room are met. The system can be inefficient if ducts are leaky or not insulated. Every seam and joint must be properly sealed. Adding a central AC system can cost less if you already have heating ducts. But remember that the ducts used for heating might not be in the right location or size for optimal cooling.

A central AC unit features a condenser placed outside your home and a fan-and-coil system that is connected by pipes carrying refrigerant. The most common design of a central A/C has the refrigerant circulating between an interior coil and a corresponding exterior condenser with compressor. The air is cooled by the refrigerant and is dehumidified in the process. The air is then circulated by a blower through the ducts all over the home.

Adding a central air conditioner can be expensive, especially if there are no ducts in your home; but most homeowners agree that it’s worth every penny. Contact American Air to have one of our HVAC specialists asses your needs and give you an estimate.
