What Should I Expect During My HVAC Maintenance

Annual HVAC maintenance is the only way to reliably guarantee that your air conditioning and heating equipment systems don’t break down. While there are some maintenance tasks, you can perform yourself. The most critical checks require a qualified HVAC technician.

You can always check to see if your local HVAC repair company offers annual HVAC maintenance contracts at an affordable cost. If you’ve ever wondered what exactly your HVAC technician looks for during their inspection, keep reading for a comprehensive breakdown of HVAC repair visits.

1. Electrical Connections

These should be tightened, tested, and replaced if required. Loose connections can cause equipment failure overheating and lead to a fire hazard. An expert HVAC technician should inspect all connections in both your furnace and outdoor A/C units at least once per year.

2. Thermostat Operation & Calibration

Thermostat calibration is primarily a test to determine if your thermostat is reading the correct temperature. Cycling equipment on and off during readings is crucial to maintaining system performance. A well-calibrated thermostat can save you money on energy bills and unexpected service breakdowns.

3. System Safety Devices

For heating repair, this step includes safety checks for flame and exhaust issues. For air conditioners, refrigerant leak prevention will prolong the life of your equipment. Both system types will require electrical output monitoring.

4. Blower Motor Operation

Without a properly working blower motor in your furnace or air conditioner, your system is inoperable. A mechanical and electrical inspection of your fan and motor should happen at least once annually.

5. Indoor & Outdoor Coils

Both coils in your A/C system are susceptible to leaking. Both need to be cleaned entirely of dirt and grime at least once annually to ensure peak performance. Dirty coils can take a significant toll on your equipment and lead to substantial emergency heating repairs.

6. Heat Exchangers & Combustion

The heat exchanger is the main chamber in your furnace. The flame enters the heat exchanger and travels through it, giving its heat away to the air passing over the exchanger. Eventually, it leaves the exchanger as exhaust, routed outside through the furnace exhaust venting. Your heat exchanger should meet high standards for restrictions and cleanliness. Otherwise, carbon monoxide and other toxins could leak into the HVAC system throughout your home.

7. Refrigerant Levels

Your A/C system is known as a closed-loop. The refrigerant in the system travels through pipes, returns to its origin point, and then starts the process again. To keep this life cycle going, you should always be vigilant of any leaks in your system. It would be best if you did not have to “top up” your refrigerant levels regularly. However, unintended leaks do happen, and they can cause serious part failures if they aren’t detected quickly.

8. Air Filters

An expert HVAC technician will know to replace your furnace filter far more often than once a year. Ideally, this step would happen on a 2-month cycle. That way, your system will remain clean and free of any consequences from restricted airflow. Your heating and cooling systems require a minimum amount of airflow during each cycle. A dirty filter is the biggest offender in causing airflow issues.

These eight areas cover most of the typical maintenance in an HVAC maintenance visit. Some local HVAC companies also recommend periodic tune-ups beyond the annual preventative maintenance.

What Happens During HVAC Maintenance Tune-Ups?

A standard HVAC tune-up will include three crucial phases: inspection, cleaning, and maintenance. The service may or may not involve repairs; it depends on whether problems appear during the inspection phase.


The HVAC technician will usually begin by inspecting your equipment. You can have everything tuned up during a single visit, or you can have the air conditioner serviced at one time of year, and the furnace serviced later. In an air conditioner, they might check the drain pan, ensure that refrigerant levels are adequate, and examine other components. In a furnace, they will look over the compressor and motor to ensure all other parts are in good shape.


Whether the tune-up involves the air conditioning system, furnace, or both, cleaning is a vital step. Even if you’re diligent about changing your air filters regularly, the technician will need to clean your system to keep it in peak condition.


Scheduled HVAC maintenance is where you get your money’s worth. If issues arise in your air conditioning or heating system, the technician will correct them on the spot. Your furnace repair technician may want to replace worn-out parts to keep them from causing severe damage later. If refrigerant levels are low, the tech will look for leaks and recharge your system. Components like capacitors and fan blades are integral to ensuring consistent and efficient operation. It’s far better to schedule these small, affordable visits preemptively than to wait until they spiral into serious breakdowns.

Keeping up with annual maintenance is your best line of defense for avoiding unexpected repair costs. When you need qualified heating repair or air conditioner repair, choose a company that knows how to deliver optimal home comfort.
