Common HVAC Issues Found During Home Inspections
When buying or selling a home, the HVAC (Heating, Ventilation, and Air Conditioning) system is a critical component that often comes under scrutiny during the home inspection process.
A well-maintained HVAC system not only ensures comfort but also has a significant impact on energy efficiency and long-term costs. In this blog post, we’ll cover the most common HVAC issues found during home inspections and what they mean for home buyers and sellers.
1. Dirty or Clogged Air Filters
What Inspectors Find:
Inspectors frequently discover HVAC systems with dirty or clogged air filters. This is a simple yet overlooked issue that can reduce airflow, strain the system, and lead to higher energy bills.
For Sellers:
Replacing the filters before an inspection is an inexpensive way to show that the system is well-maintained.
For Buyers:
If the filters are dirty, it may indicate that routine maintenance has been neglected, which could lead to larger issues down the line.
2. Condensation Leaks in Furnaces
What Inspectors Find:
Modern high-efficiency furnaces produce condensation as part of their operation. If the condensation isn’t properly drained, it can leak onto surrounding components or the floor, potentially causing rust, electrical damage, or mold growth.
For Sellers:
Ensure that the furnace’s condensate drain lines and pans are clear and functioning properly. Addressing leaks ahead of the inspection can prevent a negative impression.
For Buyers:
Condensation leaks can indicate a maintenance issue or a problem with the installation. If discovered, request further evaluation by an HVAC professional to determine if repairs are needed.
3. Improper Maintenance
What Inspectors Find:
Many HVAC systems show signs of deferred maintenance, such as worn-out belts, loose electrical connections, or dirty coils. Over time, this neglect can reduce system efficiency and shorten its lifespan.
For Sellers:
Schedule a professional tune-up before listing your home to ensure the system is in good working order. Maintenance records can be a great reassurance for buyers.
For Buyers:
Ask the seller for a history of HVAC maintenance. If no records are available, a professional inspection might be necessary to assess the system’s condition.
4. Leaking or Low Refrigerant
What Inspectors Find:
Air conditioning systems with low refrigerant levels or leaks are a common problem. These issues can reduce cooling efficiency and may point to a larger underlying problem, such as a cracked coil or damaged lines.
For Sellers:
Repairing refrigerant leaks and ensuring proper levels before the inspection can prevent red flags in the report.
For Buyers:
Be aware that refrigerant issues can be costly to fix. Consider asking for a repair or credit during negotiations if this issue is identified.
5. Aging Systems
What Inspectors Find:
The age of an HVAC system often raises concerns, even if it is functioning properly. Most systems last 20 + years depending on usage and maintenance, so an older unit may be nearing the end of its life.
For Sellers:
If your HVAC system is older but still operational, consider having it serviced before listing the home. Offering a home warranty can also alleviate buyer concerns.
For Buyers:
If the HVAC system is older, factor replacement costs into your budget and consider negotiating a credit for future upgrades.
6. Improper Installation
What Inspectors Find:
Inspectors occasionally encounter systems that were improperly installed. Issues might include poor duct work, incorrect sizing of the unit, or inadequate clearance around the equipment. These problems can affect efficiency and performance.
For Sellers:
If you suspect your HVAC system wasn’t installed correctly, a pre-inspection can identify issues that you can address proactively.
For Buyers:
Improper installation might not be immediately apparent but can lead to higher energy costs or frequent repairs. A professional HVAC contractor can provide insight into potential solutions.
7. Blocked or Damaged Duct work
What Inspectors Find:
Duct work that is blocked, leaking, or damaged is another common finding. This can lead to uneven heating or cooling and reduced energy efficiency.
For Sellers:
Inspect your duct work and seal any leaks before the home inspection. Cleaning ducts can also improve airflow and air quality.
For Buyers:
Duct work issues can usually be resolved but may require professional attention. Be sure to ask about the age and condition of the duct system.
8. Thermostat Problems
What Inspectors Find:
Non-functioning or outdated thermostats are often identified during inspections. A thermostat that doesn’t work correctly can make the HVAC system appear faulty.
For Sellers:
Upgrading to a modern, programmable thermostat is an affordable improvement that can add value to your home.
For Buyers:
If the thermostat is malfunctioning, it’s a relatively easy fix, but you may want to ensure the rest of the system is functioning correctly.
The Bottom Line
For Sellers: A little proactive maintenance can go a long way. Addressing HVAC issues before a home inspection demonstrates care and may prevent costly delays during negotiations.
For Buyers: An HVAC system is a major investment, so don’t overlook its condition during your due diligence. If the inspection reveals significant issues, consider consulting a professional HVAC technician to estimate repair or replacement costs.
