But savvy home buyers know that some of the most important things to check are the ones you don’t admire at first glance, such as the age of the roof, the stability of the foundation, or, in this case, the condition of the home’s HVAC system.
Before deciding whether to make an offer on your dream home, here are some things you should check to ensure that the HVAC system is in good condition:
Likewise, you’ll want to consider the home’s power source. Does it use a gas or electric furnace? Gas furnaces typically have lower fuel costs but are more expensive to install, while electric furnaces typically have easier and less expensive installation and maintenance but higher fuel costs.
Each system has its own advantages and disadvantages, and understanding the type of system in the home you’re looking to buy will help you determine the type of maintenance required to keep it running efficiently. A well-maintained system will keep you comfortable and safe, lower your energy use and costs, and protect your investment. If you’re unsure or need more accurate information about the type of system the home has, it’s better to consult an HVAC specialist.
Furnaces: 15-20 years
Boilers: 15-30 years
Also, keep in mind that most HVAC systems that are over ten years old are significantly less efficient than newer units being manufactured and installed today.
To find out the age of the HVAC, check the unit itself as it contains the model number and serial number—information that will tell you exactly how old the system is.
If you’re serious about a particular house, ask the seller if you can see the installation, maintenance, and repair history of the HVAC system. Check for records of annual tune-ups, filter changes, and major repairs or parts replacement. Also, don’t forget to ask if the unit was installed by a reputable company, and whether the services and repairs were done by a trained HVAC technician. Knowing these things matters because if you do purchase the home, the documentation can be helpful for future repairs.
Likewise, you might want to check the energy efficiency rating of the current system. Furnaces and heating systems should have a strong AFUE (Annual Fuel Utilization Efficiency) rating (at least 90%), while cooling systems with high SEER (Seasonal Energy Efficiency Ratio) ratings are more desirable (SEER of 15 or higher). Consider the overall state of the HVAC system in terms of energy efficiency, as it can lead to manageable utility bills and a smaller environmental impact.
Visible rust, decay, or corrosion on the unit
Odd noises such as banging or rattling
Unpleasant odors coming from the vents
Uneven airflow throughout the home
Excessive dust
Frequent cycling on and off
Don’t be afraid to check for these warning signs on the unit. Walk around the house so you can feel the difference in temperature and air or heat flow. Turn the unit on and take note of any strange noises or odd smells you experience, as these could indicate underlying issues that might lead to serious damage or a need for servicing.
If your dream home’s HVAC has been there for more than a decade or is nearing the end of its lifespan, you can use it as a negotiating point. Home sellers know that old HVAC systems can potentially scare away potential buyers, so you have more negotiating power than you think. You might want to consider asking the seller to replace the system prior to closing, or work out a deal where they will reduce the asking price for the home.
Before finalizing your offer, get a quote from a local HVAC company to better understand the cost of potential replacement. With a trusted real estate agent by your side, you can come to the negotiating table with real numbers and factor those into your offer.
