Why Proper Maintenance of Your HVAC System is Important

 

Without proper maintenance and inspections, the health of your HVAC system could suffer, leading to expensive repairs and a potential replacement. By following a regular maintenance schedule with the help of Miranda Air Conditioning Services, you could prevent problems that result in costly repairs.

• Low refrigerant charge
• Bad compressor valves
• Severely clogged air filter
• High electric bills
• Cracked heat exchanger
• Damaged compressor

And many more...

Air Handler Unit Checklist (Inside Unit)

• Air Filter
  • Why: 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 an evaporator (see dirty evaporator coil). Improper filtration of the home can cause excessive dust in the house and compound allergy problems.
• Evaporator Coil
  • Why: A dirty evaporator coil restricts the air flow and prevents the 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.
• Evaporator/Drain Pan
  • Why: Algae can cause blockage in the drain line resulting in overflow of up to 15 gallons per day. Extensive ceiling and floor damage can occur.
• Blower Motor Heating
  • Why: Symptoms are similar to a dirty evaporator coil (see evaporator coil). This can cause sudden loss of heating under peak load conditions or excessive heat due to low air flow which can damage heating coils.
• Evaporator Coil Heating (see evaporator coil)
  • Why: Can damage the high limit safety switch, heat exchanger or heating elements and shorten the life of the furnace.
• Temperature Rise
  • Why: 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 being experienced.
• Wiring/Disconnects
  • Why: Caused by loose connections/overheating. Ths can cause a sudden loss of heating under peak load conditions.
• Heat Sequence & Control
  • Why: Can cause sudden loss of heating under peak load conditions, damage heating units or shut down entire systems.
• Thermostat
  • Why: Causes uncomfortable temperature swings in living areas and can damage compressor.
• Heat Anticipator
  • Why: Causes uncomfortable temperature swings in living areas and can damage the thermostat. It greatly affects the heating efficiency of the furnace.
• Air Flow
  • Why: Can be caused by poor design, installation or damaged ducts which increase utility costs, cause rooms or areas of the home to feel uncomfortable, and shorten the life span of HVAC equipment.

Condensing Unit Checks (Outside Unit)

• Condenser Coil
  • Why: 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.
• Refrigerant Lines
  • Why: 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.
• Compressor
  • Why: (See condenser coil). Indicates compressor overworked and bearings seizing up. Also can damage capacitor (see compressor run cap) or overcharged unit (see refrigerant).
• Compressor Run Capacitor
  • Why: Caused by overworking compressor (see compressor). Weak or faulty capacitor will reduce starting ability and cause compressor not to run smoothly, which will cause compressor to overheat and fail. (A higher than normal amperage usually indicates a weak capacitor.)
• Start Capacitor
  • Why: Weak or faulty capacitor will reduce starting torque for compressor. 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.)
