Just as your car requires maintenance, so too does the air conditioning that cools your home. Neglecting to provide the necessary air conditioning service with annual maintenance is a guarantee of declining performance, a reduced lifespan, and a steady increase in energy use. Garland Heating and Air Conditioning NATE certified professionals offer the quality HVAC services your air conditioning system requires.
Air Conditioning Filters
Besides scheduling annual maintenance, routinely replacing the filter each month or as instructed by the manufacturer is essential. Filter changes assist in maintaining a clean system. Clogged, dirty filters block the normal airflow, and reduce a system’s efficiency, leading to system failure and permanent damage. With normal airflow obstructed, air that bypasses the filter carries dirt directly into the evaporator coil and impairs the coil’s ability to perform its function of keeping you comfortable. Our HVAC professionals can provide coil cleaning when required with air conditioning service.
It’s essential to use the filter recommended by the manufacturer. Some types of filters are washable, while others require changing every 1 to 3 months, depending on the type. Upgrading to a HEPA filter in a system not designed for it may result in damage, and the need for air conditioning service. How often the filter requires changing will depend on the type of filter, and the environment the system performs in. All filters should be checked each month, and more frequently when heavy dust conditions exist such as during remodeling.
Air Conditioning Coils
Over time, the evaporator coil and condenser coil will become soiled. A clean filter routinely changed assists in preventing the evaporator coil from soiling as quickly, although it will not prevent it entirely. Inspection of the evaporator coil during maintenance, and cleaning when required is an air conditioning service your HVAC technician will provide. Outdoor condenser coils can also become soiled, and are inspected and cleaned as necessary.
You should take extra care to minimize dirt and remove debris near the outdoor condenser unit. Maintain a clean area around the condenser of at least 2 feet to allow adequate airflow to the unit. This includes trimming foliage back by the same minimum distance to ensure the air flow is not impaired. In addition, when cutting grass, never aim the mower discharge chute towards the condenser, not only will the grass cause soiling of the unit, a pebble or other item can cause serious damage and costly repair.
Sealing and Insulating Air Ducts
The air ducts, also called ductwork delivers conditioned air to each room in a home or office. In order to avoid the loss of conditioned air, the ducts must be airtight. Up to 30% of conditioned air is lost from ducts in need of maintenance. Over time ducts can loosen and the seals break. Ask your Garland HVAC professional to check your ducts during your next maintenance visit. Loose tape on duct joints, disconnected or loose ducts, and gaps between the pipe are a definite sign duct repair is required.
Common Air Conditioning Problems
Refrigerant leaks, and improperly charged refrigerant is a common problem. Even in the absence of a leak, an improper amount of refrigerant affects the performance and efficiency of the unit. Common causes of AC problems include:
· Low Refrigerant– When the AC is low on refrigerant, it was either undercharged by a technician, or has a leak. Either situation will require air conditioning service by an HVAC technician. If a leak is present, professional leak repair will be required. DIY adding of refrigerant can lead to a damaged system, and requires a certified technician to determine the proper AC repair. Repair may include the need for evacuation of the system prior to adding the manufacturer specified amount of refrigerant.
· Inadequate maintenance - If you allow filters and air conditioning coils to become dirty, poor performance and efficiency will result, and it can result in premature compressor failure. The cleaning of coils, and fan motors is a component of maintenance that is provided when necessary during the annual air conditioning service.
· Electrical component failure -The compressor, fan controls, switches, contactors, and other components will experience wear over time. Oversized and undersized systems and those with failing components can run more frequently than is necessary, resulting in premature wear, and the need for replacement. Electrical connections and components are inspected during the annual maintenance call.
