After an HVAC inspection, common issues like refrigerant leaks, dirty filters, and faulty thermostats should be promptly addressed to ensure optimal system performance.
HVAC problems rank among the most common issues uncovered during home inspections. These systems account for 43% of a home’s energy use, making their proper function critical for both comfort and cost efficiency. When inspectors flag HVAC concerns, buyers and sellers must understand which repairs take priority.
Critical HVAC Repairs After Inspection
Home inspectors focus on material defects that impact safety, functionality, or major expenses. These five HVAC issues typically require immediate attention:
1. Refrigerant Leaks
Low refrigerant levels reduce cooling capacity by 20-30% and strain compressors. Look for ice buildup on coils or hissing sounds. The EPA requires certified technicians for handling refrigerants.
2. Clogged Condensate Drains
Blocked drains cause water damage in 17% of HVAC-related insurance claims. Inspectors check for proper drainage and pan overflow switches.
3. Faulty Electrical Components
Worn contactors or capacitors reduce system lifespan by 40%. Our guide to thermostat controls explains proper electrical connections.
4. Cracked Heat Exchangers
These pose carbon monoxide risks. Inspectors use CO detectors and visual checks for rust or cracks.
5. Improper Thermostat Operation
Miscalibrated thermostats waste $100+ annually in energy costs. Consider upgrading to smart models like those in our app-controlled heater review.
Negotiating HVAC Repairs
| Issue Type | Buyer Request Success Rate | Average Repair Cost |
|---|---|---|
| Safety Hazards (CO leaks, electrical) | 92% | $150-$800 |
| Functional Defects (no heat/cool) | 85% | $300-$1,200 |
| Efficiency Issues (dirty filters, duct leaks) | 67% | $50-$400 |
When to Request Repairs vs. Credits
For complex HVAC issues, 62% of buyers prefer repair credits over seller-performed fixes. This ensures quality work by their preferred contractor.
Pre-Inspection HVAC Checklist
Sellers should address these items before the inspector arrives:
- Replace air filters (dirty filters reduce airflow by 15%)
- Clear 2-foot clearance around outdoor units
- Verify all vents open and unobstructed
- Test heating and cooling in all zones
- Clean visible ductwork and registers
Document Maintenance Records
Homes with documented annual HVAC maintenance sell for 3-5% more. Keep receipts for:
- Professional tune-ups
- Filter replacements
- Part warranties
HVAC Age Considerations
Systems over 10 years old have 40% higher failure rates. The Department of Energy recommends replacement when repair costs exceed 50% of a new system’s price.
For older units, consider our built-in heater options as supplemental solutions during negotiations.
