When purchasing a home, buyers typically scrutinize roofs, foundations, and plumbing, but hidden aging HVAC systems can be equally costly. Overlooked problems by not having an HVAC inspection before closing can result in hefty repairs, reduced efficiency, and safety hazards. Here are five common HVAC pitfalls that could cost you thousands.
1. Aging Systems
Many homes on the market have aging HVAC systems that are 15–20 years old or older. While these systems may still function, they are often significantly less efficient than modern units. Older HVAC systems:
- Have a higher risk of breakdowns and costly repairs
- Use outdated technology that increases energy costs
- May no longer meet current efficiency standards
Buyers should always check the age of the HVAC system and consider negotiating a replacement or requesting a home warranty to cover potential failures.
2. Refrigerant Leaks & Compliance Updates
If a home’s air conditioner still uses R-22 refrigerant, be aware that this substance has been discontinued. Leaks in these systems can lead to significant expenses, potentially forcing buyers to replace the entire unit to comply with regulations. Look for these indicators of an R-22 leak:
- Reduced cooling performance
- Hissing noises from the unit
- Unexplained increases in energy bills
If an aging HVAC system uses outdated refrigerants, buyers should factor in the potential cost of an upgrade.
3. Poor Airflow and Ductwork Concerns
Regardless of the HVAC system’s age, flawed ductwork can severely impact efficiency and comfort. Watch for these common ductwork issues:
- Leaks and gaps that reduce airflow and increase energy waste
- Improperly sized ducts that cause uneven heating and cooling
- Excess dust and debris leading to poor indoor air quality
Call Greer’s, the professionals, to inspect the ductwork to reveal hidden inefficiencies and potential repair costs.
4. Thermostat & Zoning Problems
Inefficient and uncomfortable HVAC performance can stem from a faulty thermostat or absent zoning controls. Common thermostat issues include:
- Inaccurate temperature readings leading to overuse
- Malfunctioning sensors causing uneven heating and cooling
- A lack of zoning, leading to wasted energy in unoccupied areas
To boost efficiency and comfort, consider smart thermostats and zoning controls, but remember to include these upgrades in your budget.
5. Always Get An Aging HVAC Inspected When Buying A Home
In recent local transactions, we’ve seen several instances where hidden HVAC problems have caused major financial headaches for buyers:
- Case Study 1: A home in the Triangle area had an aging HVAC system that appeared functional but was 18 years old. Within months of moving in, the buyer faced a $10,000 replacement cost.
- Case Study 2: A buyer in the Triangle area discovered after purchase that the home’s ductwork had major leaks, reducing efficiency by 30% and requiring a $4,500 repair.
- Case Study 3: An inspection in the Triangle area revealed an illegal refrigerant refill on an older AC unit, forcing the buyer to replace the system entirely at a cost of $11,000.
Given the HVAC system’s critical role and significant expense, a professional inspection is essential for homebuyers. Identifying these five common issues allows for informed decisions and negotiation before closing. Schedule an inspection before your next closing with a call to Greer’s Certified HVAC professionals, who can prevent costly surprises.
