What are the benefits of a maintenance check?

Inspect Condenser Coils

Dirty condenser coils will raise refrigerant pressure higher than needed, increasing your electric bill. Cleaning the coils keeps your equipment at maximum efficiency while saving you money. Chemical cleaning of the coils incur an additional charge.

Check the Refrigerant Charge

The refrigerant charge is checked by measuring the temperature differential and determining electrical demand on the compressor or by reading the pressure gauges. A low or high refrigerant charge can easily go unnoticed and increase operating costs. An improper charge can also cause compressor shut-down. Periodic checks on refrigerant levels can lower your energy bills and prevent future repairs.

Inspect and Clean Out Condensate Drain

Clogged drains can increase the humidity level and cause extensive water damage. Proper maintenance of the condensate drain often prevents unwanted repair calls.

Inspect Blower Wheels

Dirty blower wheels reduce air flow, resulting in a longer operating time and increased energy cost. This problem can lead to reduced comfort and compressor failure. Avoid wasting your energy dollars by verifying that your maintenance includes a thorough check of your blower system.

Why does new equipment need a maintenance check?

You wouldn't invest thousands in a new car and then not get the oil changed, right? Here are some important reasons to properly maintain new HVAC equipment:

  • A refrigerant undercharge of only 10% can increase operating costs by almost 20%
  • A dirty evaporator, condenser and blower could increase air conditioning or heat pump electrical usage by 50% or more
  • Just 100th of an inch of dirt or film on an evaporator coil can reduce cooling and heating efficiency by 5%
  • Proper care of your equipment can save you real dollars on your utility bills
  • All leading manufacturers recommend regular maintenance to maintain peak performance

How often should your HVAC be serviced?

At the change of each heating and cooling season, we recommend homeowners have semi-annual HVAC system maintenance performed. Maintenance checks ensure your HVAC unit is running as it should and allows a professional to assess and diagnose any potential issues that could lead to repairs later on.
