What’s Included in AC Maintenance Services?


post img

An AC maintenance service may include a wide range of tasks. Air conditioners are complex machines so require thorough checks. A complete inspection and tune-up help ensure your HVAC equipment is functional and efficient. If it’s time to schedule annual maintenance, you may be wondering what to expect with an air conditioning service. Here’s an overview to help you understand what the process entails.

Air Conditioner Inspection

An operational and safety inspection is typically the first part of an annual service call. It can take an hour or more to inspect the entire system. During this time, the technician will look at the following: 

  • Thermostat: Check it’s on the proper setting, test for normal operation, and calibrate and level if necessary.
  • Air Filter: Inspect and, if necessary, clean or replace the air filter.
  • Blower Motor: Check for damage and measure its amperage and voltage.
  • Controls: Verify that the system starts, runs, and shuts off properly.
  • Moving Parts: Inspect for signs of wear and lubricate parts to reduce friction.
  • Coils: The evaporator and condenser coils are inspected for damage or wear.
  • Condensate Drain: Check for and clear blockages and treat the drain with an anti-algae compound.
  • Refrigerant: Measure system pressure and coolant levels to find signs of leakage.
  • Electrical Components: Tighten loose connections, replace faulty wires, and check the contactors, disconnect box, and other components.
  • Compressor: Measure amperage and voltage draw, inspect AC wiring, and monitor performance to identify any issues.
  • Ductwork: Air ducts are inspected and cleaned to reduce energy loss. Sources of air loss are identified to determine if duct sealing is needed.

In addition, the AC maintenance service professional measures airflow, tests safety controls, and looks for signs of pest infestations. Next, they’ll take any steps necessary to protect your HVAC system from further damage.

Clean Your AC System

Dust, dirt, and debris can build up in your AC system and interfere with its performance. Dirty evaporator and condenser coils can prevent it from absorbing or releasing heat, so it won’t properly cool your home. To compensate, the unit can run longer, which increases wear, or it can overheat and shut down; excess dirt can also decrease its lifespan. At the very least, your energy bills will go up.

A technician has the tools and equipment to properly and thoroughly clean AC coils without damaging them.

However, the coils aren’t the only components that must be cleaned. Blower components can also become contaminated. It takes precise tools and techniques to get these parts clean, so your AC runs smoothly and accumulated debris and particles don’t circulate in the system or your home.

Minor Repairs

It’s not uncommon to find small issues as air conditioning equipment ages. Maintenance technicians travel in fully stocked vehicles. This means they can fix the unit if, for example, a belt is cracked or worn. Belts can usually be replaced quickly but doing so ensures your AC will continue running. Faulty wires, contactors, capacitors, connectors, and other parts are also easily replaced. If the maintenance crew doesn’t have the part you need, they order it and schedule an AC repair for another date.

How Often Should I Schedule AC Maintenance Services?

Air conditioners should be serviced at least once a year. Most HVAC specialists recommend scheduling maintenance in the spring, so there are no cooling issues to contend with during the warmer months. Your AC system will also work efficiently for the entire season, maximizing savings on energy bills.

What Does AC Maintenance Cost?

The price of your AC contractor’s service plan may include numerous maintenance tasks. Other companies charge a flat rate or set an hourly rate (especially if the job takes more than an hour). Therefore, maintenance rates can vary, and you’ll pay more if repairs are needed (depending on your equipment warranty).

How Often Should I Replace an AC Filter?

Don’t wait for yearly service to have the filter replaced. An AC filter should be changed at least every 3 months. Check it monthly to make sure it’s not dirty or clogged. Filters may need more frequent changing if you live in a dusty home or have pets.
