Buying a new home is an exciting step, but before you finalize your purchase, it’s crucial to evaluate the condition of the home’s HVAC system. Heating and cooling make up a significant portion of your home’s comfort and energy costs. At Kearney & Sons, we help homeowners across Hampton, Poquoson, Newport News, and Williamsburg, VA make informed decisions by offering professional HVAC inspections and honest guidance. Here’s what you need to know before signing that contract.
1. Age and Maintenance History
HVAC systems don’t last forever. Air conditioners and heat pumps typically have a lifespan of 10–15 years, while furnaces can last up to 20 years with proper care. Ask the current homeowner for any maintenance records and find out when the system was installed. A system that has been well-maintained is likely to perform more efficiently and last longer than one that’s been neglected.
If the HVAC system is older or lacks proper documentation, it may be worth scheduling a preventive maintenance visit or inspection to assess its condition. This will help you anticipate potential repair or replacement costs down the road.
2. System Efficiency and Energy Costs
High-efficiency HVAC units can save you hundreds of dollars annually on energy bills. Look for systems with high SEER (Seasonal Energy Efficiency Ratio) ratings for cooling and high AFUE (Annual Fuel Utilization Efficiency) ratings for heating. The higher the rating, the more efficient the system.
Older HVAC units are generally less efficient and may lead to higher monthly bills. Ask the seller for past utility statements to get a sense of operating costs. If the system is outdated, consider the long-term savings you could get from a new energy-efficient heating system or air conditioning installation.
3. Design, Layout & Ductwork
Even a modern HVAC system can underperform if it’s poorly designed or installed. Ductwork layout plays a huge role in airflow and overall system performance. Ask whether the ductwork has been inspected or sealed. Leaky or undersized ducts can reduce efficiency and compromise comfort throughout the home.
Also check the location of HVAC equipment. Units located in unconditioned attics may experience more wear and tear. Make sure there is easy access to the system for regular maintenance, especially for tasks like filter replacement and indoor air quality improvements.
4. Type of Refrigerant
If the system still uses R-22 refrigerant (phased out in 2020), be aware that servicing it can be difficult and expensive due to limited availability. Newer systems use more environmentally friendly refrigerants like R-410A. This is another reason to consider an upgrade if the system is more than 10 years old.
Our team at Kearney & Sons offers AC repair and replacement services to help homeowners transition to modern, compliant HVAC systems that meet today’s energy standards.
5. Transferable Warranties and Service Agreements
Some HVAC warranties are transferable, which can add value and peace of mind when purchasing a home. Ask whether the current system has an active warranty or a service agreement in place. These plans often cover annual tune-ups, discounts on repairs, and priority scheduling.

Frequently Asked Questions
How long does an HVAC system typically last?
Most HVAC systems last between 10 and 20 years, depending on the type of equipment and how well it has been maintained. Regular maintenance can extend the life of your system significantly.
Is a home inspection enough to evaluate the HVAC system?
Standard home inspectors perform a basic overview, but for a detailed evaluation, it’s best to schedule a dedicated HVAC inspection with a licensed contractor like Kearney & Sons. We check performance, refrigerant levels, ductwork, and more.
What does it cost to replace an HVAC system?
The cost varies depending on the size of the home, type of system, and energy efficiency ratings. On average, complete replacements can range from $5,000 to $12,000. We offer free estimates on heating installations and air conditioning installations.
Can I upgrade just part of the HVAC system?
Yes, but compatibility is key. For example, installing a high-efficiency air conditioner with an older furnace may reduce performance. Our technicians can recommend the best approach based on your current setup and budget.
