How often should HVAC be serviced to save on energy bill?

HVAC professionals recommend regular maintenance of your HVAC system once a year. Annual maintenance should be carried out for your home’s heating and cooling systems even if you think there’s nothing wrong with them.

This blog will cover more on the factors that affect how often your air conditioner needs servicing. Moreover, we will discuss some of the benefits of having HVAC maintenance such as energy efficiency and optimal performance. 

Furthermore, you will learn what is included during air conditioning maintenance so you’ll have an idea of what an HVAC company does to your unit. 

How often should your air conditioner be serviced?

Here are two factors you need to consider how often your unit needs servicing.

Seasonal Changes

Your HVAC system should be in good working condition all year round, especially during the months when you need it the most. The changing of the seasons is one thing to consider when thinking about the frequency of HVAC maintenance.   

You need to have your air conditioner inspected and serviced before summer arrives. Spring is the ideal time for an air conditioner tune-up. Your air conditioning unit should be ready to cool your home during the warmest times of the year.

Similarly, fall is the best time to have your heating system inspected and cleaned. It is wise to have it running at its optimal condition as winter approaches.  

System Considerations

The type and the age of your unit are the main factors that affect how often your HVAC system should be inspected.

An older A/C unit needs inspections more frequently than newer ones.

Certain types of HVAC units require extra attention. For instance, a split type air conditioner comprises an indoor and an outdoor component. Since split type HVACs have more components, they need to be inspected more often.

Why your air conditioner needs to be inspected regularly

Air filters and condensing coils are key areas in air conditioners. The accumulation of dirt and dust over time can affect an HVAC unit’s performance. Dust and dirt buildup in these key areas can cause your unit to lose 5% of its operating efficiency.

Without regular maintenance on your air conditioning system, your unit can’t cool your home as efficiently as it should if it were clean.     

Preventive maintenance by a reputable HVAC contractor can help you save on utility bills, minimize the need for costly repairs, and extends the lifespan of your air conditioning unit.

Lower utility bills

Routine maintenance can help your HVAC systems perform more efficiently and improve your unit’s energy efficiency by 20%. The more effective your air conditioners perform the lower your energy bills will be.

Fewer repair bills

An experienced HVAC technician can detect and address potentially dangerous conditions in your unit during an inspection. Regular maintenance can help prevent the possibility of having costly repairs on your air conditioning system.

In contrast, minor problems in your A/C unit, if left unnoticed, can grow into larger, more expensive technical issues. Also, replacing an air conditioning unit can cost thousands of dollars.

Longer life span

In general, an air conditioner can run for 10 to 20 years without the tune-ups. However, air conditioning maintenance can help your unit last for 30 years.

On the other hand, neglecting the necessary maintenance of your unit while steadily using energy can cause a continuous decline in its performance.   

What does HVAC system maintenance include?

Aside from cleaning evaporator coils and dirty filters on your home air conditioning unit, HVAC regular maintenance check-up includes inspecting the:

  • Refrigerant levels
  • Motors, belts, & other mechanical components
  • Fan, blower motors, and condenser
  • Thermostat
  • Ductwork seals, kinks, & holes
  • Electrical connections and
  • Condensate Drain line

Refrigerant levels

While the refrigerant is included in the checkup, it is unnecessary to refill it every year. Most HVAC contractors only refill the refrigerant only once, even if there are leaks. Leaks and other minor problems can be addressed easily but a diagnostic test is still required.

Motors, belts, and other mechanical components

HVAC units, like other machines, have mechanical parts that require regular servicing. Certain mechanical parts in HVAC systems need oil to keep them running smoothly.

Fan, blower motors, and condenser

As part of preventative maintenance, the HVAC technician will clean the fan, blower, and condenser coils. However, if there is an excessive build-up of dust and dirt, the technician may need to take the whole system apart.

Taking an HVAC system apart is beyond the regular maintenance arrangement and may require additional diagnosis and charges.


A thermostat is an integral part of an HVAC system and an inspection must be carried out during maintenance. A thermostat that doesn’t turn on may mean a minor problem like a dead battery or it might be a larger issue.

Ductwork seals, kinks, and holes

Ductwork (or duct system) is an essential part of a central air conditioning system. Ductworks should not have kinks and holes so it can function properly.

Just like kinks and holes, seals on the ductwork requires regular inspection as they can become undone over time. Many homeowners often overlook problems in the ductwork which have resulted in wasted energy.

Electrical connections

A technician will check all electrical components which include electrical connections, terminals, and fuses.  

During an inspection an HVAC specialist will check for:

  • Loose and disconnected wires. Rodents chewing on electrical wires are the most common cause of an electrical problem.
  • Short circuits can lead to bigger problems if left unchecked.
  • A blown fuse or breaker

Drain line 

A condensate drain line inspection can prevent structural damage to your home. Its primary function is to collect condensed water and transport them into the catch pan. 

Drain lines need inspection as algae and debris can cause obstruction, which results in water backing up into the catch pan and overflowing. Water overflowing in your home can cause devastating structural damage.
