If you want to place your home in the market sometime soon, you need to either maintain or increase its value. You can achieve this by performing regular check-ups on every component of your house. Inspect every corner of your home for any defects that are due for repair. It is also essential that your heating, ventilation, and air-conditioning (HVAC) system is in top condition, as most people are particular about a house's mechanical features. Here is a checklist of preventive maintenance for your HVAC system.

Purchase the Standard Filter

Make sure that you are purchasing legit filters for your HVAC system. Filters are essential components of your mechanical system for protection against dust. New pleated filters give you the highest efficiency in collecting even the tiniest particles that carry bacteria.

Change Filters Every Three Months

You should change your HVAC filters every three months, but conduct inspections every month to check for potential clogs. Homeowners who have pets may need to replace their filters every month.

Adequate Clearance

The installation of heat pumps and outdoor air conditioning units should have a minimum of two feet clearance.

Clear Out Debris

Inspect your HVAC units thoroughly for debris like twigs, leaves, and pollen. Do this weekly during the dry season from all corners of your heat pumps and outdoor air-conditioning units. Also, be mindful of grass clippings going into the units when you do your lawn mowing. You must prevent a prospective buyer from getting dismayed if they find out that you’re not taking care of your HVAC system. Taking care of your mechanical system will increase the value of your house.

Check the Insulation Covering on Refrigerant Lines

You should check these components monthly and replace any damages leading to your house.

Your Unit Must Be on a Level Position

Make sure that your HVAC units are on level position. You can check this every year and see that your heat pumps and outdoor air-conditioning units are in a proper position, with firm mounting on level ground. The reason for maintaining the right position is to prevent fluids from spilling.

Clear the Clogs

You should pour a mixture of water and bleach down the air-conditioner condensate drain line to clear clogs due to molds and algae buildup.

Turn off Water Supply

During summer or fall, you should change the humidifier wick filter and set the humidistat within 35% to 40% relative humidity. While doing this, you should turn off the water supply, then turn it on again after the process.

Home’s Registers

To prevent putting more strain on your HVAC system, do not adjust your damps or flaps and regulate your home’s registers to 20% opening.


It would be best if you replace the battery for your carbon monoxide detector every year.

Perform an Upgrade

The last thing you want to perform maintenance work to your HVAC system is an upgrade. If you live in an old house, you might be using an older mechanical system. An upgrade may be imminent, especially if you are putting your home on the market soon, which would create a higher selling cost for your house as you present it with an energy-efficient HVAC system. Upgrading your system is a good investment for your home.

In performing maintenance works on your HVAC system, you might want to consider hiring professionals to do it. There are specific components that can be difficult for you to do, such as electrical and tweaking mechanisms. Often, relying on professionals like Accuserv can be a big help to ensure maintenance works are done optimally. Follow these maintenance plans to prolong the life of your mechanical system and increase its effectiveness.
