How Do Costs Differ By HVAC Inspection Type?
The most common type of HVAC inspection will include every component of your HVAC system — but in some cases, you may have just one system or component inspected because you suspect there is a problem.
For example, you may notice that your air conditioner isn’t working as it used to, or you think something is wrong with your ducts. In any case, individual system inspections will cost less than a full HVAC inspection.
| HVAC Inspection Type | Low Cost | High Cost |
| HVAC inspection | $150 | $500 |
| Boiler Inspection | $100 | $250 |
| Heat pump inspection | $100 | $250 |
| Air duct inspection | $80 | $180 |
| AC inspection | $75 | $150 |
| Furnace inspection | $70 | $130 |
Cost data includes the unit, labor, and demolition, if applicable. Data gathered from RS Means construction materials and labor database.
HVAC Inspection
A full HVAC inspection costs between $150 and $500 on average. This comprehensive appointment includes a complete inspection of your heating system, cooling system, and ductwork. HVAC contractors will take at least an hour to complete the inspection — and once they’re done, they’ll recommend necessary repairs and perform minor maintenance.
Boiler Inspection
A boiler inspection costs between $100 and $250 on average but can cost more if you have a complex system or need costly repairs. When you pay for a boiler inspection, the technician will fully examine your boiler and ensure that it has no leaks, has good fuel levels, and has no ventilation issues. If major issues are discovered, they may recommend a boiler replacement.
Heat Pump Inspection
A heat pump inspection costs between $100 and $250 to conduct. During this type of HVAC inspection, the technician will make sure your heat pump is in working order by looking at the refrigerant levels, electrical connections, filers, fan motor, and other components. They will also check for common heat pump problems like leaks and look at your thermostat.
Air Duct Inspection
You can expect an air duct inspection to cost between $80 and $180. During this process, the HVAC inspector will ensure that your ducts are working efficiently and without leaks. This type of inspection takes at least an hour — if not two — because the technician will check the inside of your ducts, outside systems, and air pressure and perform any necessary cleaning. Sometimes, they’ll even use video technology to inspect your ducts.
AC Inspection
If you want your air conditioner to run smoothly during the heat of the summer, then you have to schedule regular inspections. These air conditioner inspections usually cost between $75 and $150 and include a comprehensive review of your system. During an air conditioner inspection, your HVAC professional will check the following before recommending repair or replacement:
- Air blower
- Condenser and evaporator coils
- Electrical wiring
- Refrigerant levels
- Safety devices and control systems
- Thermostat settings
Furnace Inspection
Your furnace is the sole system in charge of keeping your home warm during cold winter, so regular check-ups are a must. An inspection for your furnace costs between $70 and $130 on average. Most furnace inspections will include a full check of your burners, filters, fans, and other major components to make sure the furnace turns on and works properly. If you get a furnace inspection, the HVAC technician will include the following in their inspection:
- Check air ducts for leaks and blockages
- Check filters
- Check for carbon monoxide leaks
- Examine electrical components
- Inspect burners and combustion chambers
- Inspect the flue system and venting
- Test thermostat
How Does HVAC Maintenance Affect HVAC Inspection Pricing?
If you have an inspection done and the technician reports that you need repairs or some maintenance, your total HVAC maintenance cost will increase. You’ve done the inspection because you want to ensure your system is running properly — so in many cases, this extra cost can be expected.
For example, you may pay between $80 to $180 to inspect your air ducts, but you may pay another $300 to $750 to get your ducts cleaned. This will bring your total cost to between $380 and $930.
| HVAC Inspection Type | Low Cost | High Cost |
| Air duct cleaning | $300 | $750 |
| Changing air filter | $20 | $50 |
| Drain line cleaning | $70 | $450 |
| Evaporator and condenser coil cleaning | $80 | $400 |
| HVAC cleaning | $300 | $700 |
| Refill freon | $50 per pound | $100 per pound |
| Refrigerant leak | $200 | $1,200 |
Cost data includes the unit, labor, and demolition, if applicable. Data gathered from RS Means construction materials and labor database.
Which Factors Impact HVAC Inspection Cost Estimates?
Most HVAC inspections cost around $300 — but depending on certain factors, this cost can be more than you originally expected. The factors that are most likely to impact the cost of your HVAC inspection include the following:
- Annual maintenance plan
- Homebuyer inspection
- Labor costs
- Travel costs
Annual Maintenance Plan
Many of the best HVAC companies offer an annual maintenance plan that covers HVAC tune-ups, maintenance, and discounts. If your company offers such a plan, it’s worth the $150 to $500 per year. Even if you sign up for these packages just for the maintenance, they are a good deal — not to mention that you can save money with the other services that often come as part of the plan:
- Air duct cleaning
- Air filter change
- Freon refill
- HVAC cleaning
- HVAC preventative maintenance
Homebuyer Inspection
If you are buying a home, you could save thousands of dollars with an HVAC inspection. The last thing you want is to move into your new home and have your furnace or AC system break down. An HVAC inspection can help you determine what needs to be done before you sign the deed. Home inspections cost between $100 and $500, covering the inspection and necessary paperwork.
Labor Costs
The cost of labor depends on your location, chosen HVAC contractor, and the nature of the service. Quick, less complicated jobs will be less expensive, but you’ll pay significantly more for complex repairs. Generally, you can expect to pay $60 to $150 per hour in labor costs. Along with labor, you may also need to pay a service call fee of $75 to $125.
Travel Costs
If you live further away from urban areas, you may need to pay a travel cost of $25 to $50 — this fee will depend on how far the HVAC technician has to travel. So if you live in a remote location, you may want to consider the HVAC company nearest to you.

Professional vs. DIY HVAC Inspection
A clean, well-maintained system runs better than a dirty one. So, it’s important to schedule professional inspections to identify potential problems and save money on energy bills. You can do your own HVAC inspection, but you may miss something that could lead to serious — not to mention expensive — problems.
Doing an HVAC Inspection Yourself
Although we recommend hiring a professional HVAC company to inspect, you can do it yourself. You may not have all the tools and equipment to do a comprehensive inspection, but you can look for common problems by doing the following:
- Shut off the system’s power.
- Remove debris from your external HVAC unit.
- Clean the fins, the evaporator coil, and around the unit.
- Replace the filter.
- Inspect the ductwork.
- Contact your local HVAC provider if you notice a problem.
