Commercial AC Maintenance & Tune-ups in Phoenix, AZ

Owning a business in the Phoenix area over the summer can be a nightmare if the air conditioning goes on the fritz. When the temperature is not comfortable, employees are unproductive and clients are unhappy. One of the best ways to prevent serious air condition malfunctioning is to conduct regular commercial ac maintenance. This ensures the HVAC system functions efficiently and properly.

What Are The Benefits of Commercial AC Maintenance?

Although some business owners choose to wait until an HVAC unit breaks down to repair it, smart owners schedule a commercial ac tune-up once or twice a year. One of the benefits is to catch any issue before it becomes a major problem, which saves money in the long run.

Regular maintenance also ensures the system works at its greatest efficiency, even during the hottest days of summer. This helps to keep energy costs low. Knowing that your system is maintained properly also gives business owners a peace of mind, as they know the air conditioning is not going to quit working during Phoenix’s days of 100+ degree weather.

What Is Included With Commercial Air Conditioning Maintenance Service?

When you hire AccuTemp to perform maintenance on your air conditioning unit, you can rest assured our technicians perform a full-service check on both the inside and outside units. 

On the inside unit, the technician will inspect the following:

  • Air filter
  • Evaporator coil and drain pan
  • Blower motor
  • Temperature controls and thermostat
  • Wiring
  • Heat sequence and control
  • Heat anticipator
  • Airflow

On the outside unit, inspections occur on the:

  • Condenser coil
  • Compressor and compressor run capacitor
  • Refrigerant lines
  • Start capacitor

Certain things, like the air filter, should be replaced every year or so, and the technician will do that if necessary. If there are any other issues, the technician will recommend the best course of action.

Air Handler Inside Unit Check

Air Filter

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.

Evaporator Coil

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.

Evaporator/Drain Pan

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 sudden loss of heating under peak load conditions or excessive heat due to low air flow 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.

Temperature Rise

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 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.

Heat Anticipator

This can make for uncomfortable temperature swings and damage the thermostat. It greatly affects the heating efficiency of the furnace.

Air Flow

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 life span of all HVAC equipment.

Outside Condensing Unit Checks

Condenser Coil

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

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.

Start 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.
