Homebuyer’s HVAC Inspection Checklist

Buying a new home is already a very overwhelming process. With so much to do and so much paperwork to fill out, it can be easy for things to slip through the cracks. When it comes to your potential new home’s HVAC system, you’re probably relying on the home inspection to tell you everything you need to know. Though this is fairly reliable, why not be knowledgeable enough to spot or notice potential system hazards or inefficiencies. These tips will help you, the buyer, do your own HVAC system check and save you from unexpected expenses after purchasing and settling into your beautiful new home.

Room to Room

Pay attention to the temperature and level of moisture as you move from room to room. Are there drastic changes in particular rooms or areas of the home?

Vent Flow

Take notice of where the vents are located for both intake or outflow. Is the constant air flowing through those vents? Does the force air change from vent to vent? room to room?


Are there multiple heating/cooling zones in the home? If not, is your current system capable of zoning should you choose the setup in the future?


Get information on how old the make and model of the installed system is. Then, ask when it was installed. Research that specific model and get the facts.

History of Maintenance

Ask the current homeowner to provide as much maintenance and repair history as possible. This will help you determine where you are in the maintenance interval and how well the system has been maintained.

Warranties and Service Plans

Are there any active warranties or service plans on the HVAC system? More importantly, are they transferable to you or can you take advantage of them as long as they are in place?

Equipment Manuals

Make sure to collect any and all HVAC machinery equipment manuals. If the physical manuals are not available to you, make sure to get the model or serial numbers since most manuals can be digitally downloaded online. Manuals can prove helpful in an emergency.

Thermostats & Detectors

Thermostats and Smoke/Carbon Monoxide Detectors will be checked during the inspection, but it’s good to know their age, model and capability. Decide whether or not you would want to replace them or when their lifespan is expected to end.

Physical Unit Inspection

Pay attention to any dust, rust or noises. Even the smallest speck or slightest noise can be an indicator of a developing problem. Better safe than sorry.

Stay or Go

In the end, is the system worth keeping or will you do away with it completely? This is no small expense, so it’s something you may want to try to negotiate into the cost of the house or set aside funds to replace.
