Annual Air Conditioning Service
Arlington TX HVAC Maintenance Agreements Providers
Annual maintenance of your Arlington TX commercial or residential air conditioning system is essential to both your comfort and to manage your energy costs. Although your system primarily controls the air temperature of your house, it is also responsible for maintaining the air quality and reducing the humidity in your home. If the system runs constantly and barely keeps you comfortable, a problem can probably be uncovered by a comprehensive tune-up from Metro Energy Savers. Here is a brief description of the problems that can occur when your A/C inside unit and outside unit are not properly maintained.
Air Handler Inside Unit Check
Dirty air filters are a frequent cause of low suction pressure in air conditioning systems and high temperature rise in heating systems. Dirt will also collect on evaporator coils. Improper filtration of the home can cause excessive dust in the house and compound allergy problems.
A dirty evaporator coil restricts air flow and prevents proper transfer of heat to the refrigerant and can cause compressor failure. Compressors are not designed to pump liquid refrigerant and this can cause the compressor to fail.
Algae can cause blockage in the drain line, resulting in overflow of up to 15 gallons per day. Extensive ceiling and floor damage may occur.
Blower Motor Heating
Symptoms are similar to a dirty evaporator coil. You may experience a sudden loss of heating under peak load conditions or excessive heat due to low airflow which can damage heating coils.
Evaporator Coil Heating
This can damage the high limit safety switch, heat exchanger or heating elements and shorten the life of the furnace.
When a maximum temperature rise is reached with a minimum amount of air flowing it can possibly cause damage to the heater. When a minimum temperature rise is reached with a maximum of air flowing it can lead to cold drafts.
These are caused by loose connections and overheating. This can lead to a sudden loss of heating under peak load conditions.
Heat Sequence & Control
Such an issue can cause a sudden loss of heating under peak load conditions, damage heating units or shut down entire systems.
A damaged thermostat leads to uncomfortable temperature swings in living areas and can damage compressors.
This can make for uncomfortable temperature swings and damage the thermostat. It greatly affects the heating efficiency of the furnace.
This is the result of poor design, installation, or damaged ducts, which increase utility costs, cause rooms or areas of the home to feel uncomfortable, and shorten the lifespan of all HVAC equipment.
Outside Condensing Unit Checks
The lack of cooling air doesn’t remove heat from refrigerant properly. Since refrigerant also cools the compressor, it can cause the compressor to overheat and fail.
Often the system capacity is reduced, and oil return problems are frequently experienced with undersized lines. This can shorten the life of the compressor and increase cooling/heating bills.
Indicates compressor overworked and bearings seizing up. It can also damage the capacitor or overcharged unit.
Compressor Run Capacitor
Issues are caused by overworking the compressor. Weak or faulty capacitors will reduce starting ability and cause compressors not to run smoothly, which will cause compressors to overheat and fail. A higher than normal amperage usually indicates a weak capacitor.
Weak or faulty capacitors will reduce starting torque for compressors. The compressor will overheat and fail. Be sure to check the potential relay before the unit is placed back in service or the new capacitor may be damaged.
