1. Inspecting and Changing Filters

Filters can get dirty easily, especially if you live in a location that can be dusty. The HVAC system filters trap all kinds of dust, debris, germs, and clean the air. They’re responsible for maintaining the indoor air quality. If they’re not cleaned and replaced regularly, your HVAC system will eventually stop performing as you expect it to. The heating and cooling will be inefficient and the indoor air quality will worsen. Inspecting and changing the air filters is one of the most important aspects of HVAC maintenance.

2. Visual Inspection of the Entire System

You should get your HVAC system visually inspected at least once every year to make sure all the systems are working well. This inspection is an important aspect of HVAC maintenance. If you don’t get your system inspected, you won’t notice a problem until it stops working in the middle of winter. That’s the last thing you want because you will have to hunt for alternative heating sources until the system is repaired. Regular inspection and maintenance also helps keep it in good shape and prolongs its life.

3. Cleaning and Removing Debris

Dust and debris don’t just settle in the filters. They can also collect on blowers, moving parts, condensing units, and other such important aspects of your HVAC system. A light layer of dust is unavoidable but too must debris can cause a lot of damage to the HVAC system. A professional will carefully clean all the accumulated dust and debris and make sure there’s no corrosive damage to the internal systems.

4. Checking the Condensate Drain

The condensate drain in your air conditioner and heat pump  should be free of all clogs and debris. Clogs can obstruct the flow of condensed water and cause moisture accumulation within the system. Excess moisture can cause problems like mold, water damage, high levels of humidity in the property, uneven temperature regulation, bacteria, and compromised air quality. A professional maintenance technician will flush and clean the condensate drain to ensure all excess moisture flows away from the system.

5. Checking the Thermostat Settings

Most HVAC systems now have programmable thermostats that allow property owners to control the temperature and set it on a schedule. For example, you can set the thermostat to lower the heat when you’re not in home to save money on the energy bills and ensure the system isn’t overburdened. A professional technician will check the thermostat during the annual maintenance to ensure the actual temperature and the temperature on the thermostat matches. If there’s a difference in the temperature, the technician needs to check the thermostat’s performance or assess the entire HVAC system.

6. Checking the Electrical Connections and Voltage

Most people don’t realize that the HVAC connections and systems can come loose or break over time. That can compromise the performance of the system and eventually damage it enough that you need to invest in furnace replacement or AC replacement. The maintenance technician will carefully examine the connections and evaluate the performance of the system. They’ll look for frayed and damaged wires and replace them in order to minimize the risk of fire and component failure.

7. Lubricating Moving Parts

HVAC systems have moving pasts in compressors, circulation units, and furnaces. These moving parts need to be lubricated regularly to minimize friction and the resultant wear and tear. The technicians will carefully clean and remove all traces of debris from the moving parts and apply the required amount of lubricant to control friction. This process should be repeated often to protect the HVAC system from excessive damage.

8. Inspecting Exhaust Outlets

The exhaust outlets allow all dangerous gases to escape your property so there’s no risky buildup of carbon monoxide and other such gases. If the exhaust outlets are clogged, they can lead to a dangerous build-up and compromise your safety. The technician will assess all of these aspects of your system and check the chimney flue and vent stack as well. They will look for signs of corrosion, leaks, and back draft and repair the problem during their maintenance runs.

9. Checking Fuel Lines and Connections

The fuel lines that supply gas to your furnace should also be inspected regularly. Leaking gas and fuel can be a fire hazard. Disconnected fuel lines can compromise the efficiency of the HVAC system as well. Soot can accumulate in burners and cracked heat exchangers can have an impact on the system’s efficiency as well. The maintenance technicians will assess all of these aspects of the furnace and carefully and remove all clogs and traces of soot.

10. Checking the Refrigerant Levels

Your air conditioner should have enough refrigerant in it to cool the air efficiently. If there isn’t enough refrigerant, the compressor will have to work harder to achieve the desired level of temperature. That can cause extensive damage to the system and eventually force you to replace it.
