Beat the Heat: 7 Questions to Ask About a Home’s Cooling System Before Buying

A home’s cooling system can make or break your comfort—and your budget. Before you sign on the dotted line, ask these seven questions to avoid sweating over unexpected surprises later.

1. How old is the HVAC system? The age of the heating, ventilation, and air conditioning (HVAC) system matters. Most systems last 10–15 years, depending on maintenance. An older system may need costly repairs or replacement soon. Ask for the installation date and request maintenance records.

2. Is the system energy-efficient? An efficient HVAC system can save you hundreds on utility bills each year.

You need to know… Is it ENERGY STAR certified? What’s the SEER (Seasonal Energy Efficiency Ratio) rating? Higher SEER ratings mean better efficiency and lower operating costs.

3. Has the system been regularly maintained? Proper upkeep can significantly extend the life of an HVAC system. This means regular filter changes, annual servicing, and cleaning. Neglect often leads to breakdowns and reduced performance.

4. What type of insulation does the home have? Even the best cooling system can struggle if the home isn’t properly insulated.

Be sure to ask: Is the attic insulated? What type of insulation is used in the walls? Poor insulation forces the HVAC system to work harder, driving up energy costs.

5. Are the ducts in good condition? Leaky or dirty ducts can reduce airflow and efficiency.

What to ask: When were the ducts last inspected or cleaned? Are there any visible signs of leaks or damage? Well-maintained ducts ensure cool air reaches every room efficiently.

6. Are there any smart features? A smart thermostat or zoned cooling can add both comfort and savings. Ask if the home has a programmable or smart thermostat. These devices allow you to control temperatures remotely and set schedules to save energy when you’re not home.

7. What’s the average energy bill? Utility costs can give you a real-world view of how well the cooling system performs.

What to ask: Request a few months of energy bills from the current owner. High costs could signal inefficiencies or problems with the system.

Stay Cool and Confident

A home’s cooling system is one of the most important factors in maintaining comfort and controlling expenses—especially in the summer. By asking these questions, you’ll avoid costly surprises and make an informed decision about your investment.
