What Does an Annual HVAC Maintenance Check-up Include?

Scheduling an annual HVAC maintenance inspection is an excellent way to ensure that your HVAC system doesn’t break down, help you save money on expensive repairs, and extend the life of your system. While you can perform some maintenance tasks on your own, such as filter changes and external unit cleaning, most tasks require the services of a qualified technician. If you’re wondering what one hour air conditioning & heating NJ can offer you, you’ve come to the right place!

What Happens During an HVAC Maintenance Inspection?

Your HVAC technician will inspect, clean, and maintain your HVAC system. If any parts need to be repaired or replaced, it will be done during the inspection or at a later date.


Your HVAC technician will inspect your HVAC equipment. You’ll have the option of getting both your AC unit and furnace inspected at the same time, or you can have your AC unit inspected in the spring and your furnace inspected in the fall. When checking your air conditioner, the technician will likely inspect the drain pan, check refrigerant levels, and examine other components. When checking your furnace, the technician will look at the compressor and motor to ensure that everything is in good working order.


Cleaning your HVAC system is an essential part of your annual maintenance inspection and will help your system last longer. Your HVAC technician will change your filter, clean your indoor and outdoor coils, and clean your heat exchanger.


If your HVAC system is in need of repairs, the technician will make the necessary repairs or replace any worn parts. For example, if refrigerant levels are low, your technician will look for and repair refrigerant leaks.

What Components Will Your HVAC Technician Examine?

Electrical Connections

Loose electrical connections are a hazard and can cause your equipment to fail or overheat. Your AC unit’s electrical connections will be tested and, if necessary, tightened or replaced. Make sure that you get a maintenance check-up every year to ensure that all of the connections are tested.

Thermostat Operation and Calibration

During your routine maintenance check, an HVAC technician will make sure that your thermostat is properly calibrated, or reading the correct temperature. An uncalibrated thermostat can cause your system to run continuously, raising your energy costs significantly.

Safety Checks

Your HVAC technician will ensure that your HVAC system safety features are intact. Your AC unit’s fuse, surge protectors, and fail-safes will be tested. The professional HVAC technician will also check your furnace’s flame rollout sensor, flame proving sensor, high temperature limit control, flue exhaust pressure sensor, and fan limit sensor on your furnace to confirm that they are all working. Safety checks should be done once a year to ensure your family’s safety.

Heat Exchanger

During a one hour air conditioning & heating NJ inspection, an HVAC technician will check your furnace’s heat exchanger to determine if it is cracked. A cracked heat exchanger is a serious issue since hazardous gasses such as carbon monoxide, sulfur dioxide, and nitrous oxide could leak out into your home, resulting in illness or death.

Refrigerant Levels

Your HVAC technician will check the refrigerant levels in your AC unit and make sure that it isn’t leaking. If it is, they will either patch up or replace the entire coil, depending on the location and severity of the leak. Refrigerant leaks can cause your air conditioner to cool inefficiently, forcing your system to work harder and increasing your monthly energy bills. Refrigerant leaks are also harmful to your health and hazardous to the environment. This is one of the many reasons why an annual maintenance tune-up is essential.

Blower Motor Operation

HVAC systems require properly working blowing motors to heat and cool homes. Hire a one hour air conditioning & heating NJ service to mechanically and electrically inspect your fan and motor once a year.

Indoor and Outdoor Coils

Air conditioners have both an indoor evaporator coil and an outdoor condensing coil. Unfortunately, dirt, dust, and debris can build up on the surfaces of the coils. If dirty coils are ignored, the buildup can reduce your system’s ability to provide cool air. In more extreme cases, dirty coils can actually block airflow, resulting in uncomfortable temperatures in homes and higher energy costs. This will cause your air conditioner to overwork, which can result in a shorter lifespan. The indoor and outdoor coils should be cleaned once a year by a professional HVAC technician to ensure peak performance and longer system life.

Air Filters

A dirty air filter can cause your HVAC system to overwork, resulting in higher monthly utilities and causing equipment damage. We suggest that you change the filters yourself or have a professional HVAC technician do it every 1-3 months. This will keep your system clean and prevent restricted airflow.Keeping up with your annual maintenance check-ups is the best way to avoid unexpected HVAC repairs.
