When it comes to HVAC systems, it’s essential to get an inspection regularly. A professional technician will be able to diagnose any potential issues and suggest any necessary repairs or replacements before they become more significant problems down the line. The cost of an HVAC inspection typically varies from $250 to $450 depending on several factors, such as:

  • System type and complexity
  • Inspection extent
  • House size
  • Location

Nationwide, the average cost for an HVAC inspection is about $300 per visit. A basic inspection includes checking the heating, cooling, and ventilation system’s functionality, inspecting ductwork for air leaks, testing safety controls, measuring airflow and temperature levels, and checking for any other signs of potential system failure.

At the extreme ends of the cost scale, an HVAC inspection may range from $100 to $550, depending on the examination type. A comprehensive (high-end) examination would include testing the system’s performance, evaluating its overall condition and components, examining energy usage, and providing a written report.

A pro technician can offer insight into how your system can become more efficient and reduce energy costs. 

HVAC Inspection Costs by Unit Type

The total cost of an HVAC inspection can vary depending on the type of unit you have installed, its age, and the complexity of the inspection. Generally, a basic HVAC system inspection will cost between $250 and $450, as most inspections take an hour or two to complete.

If your HVAC system has more than one unit, or the tech needs to check components that are difficult to access, then you can expect the inspection cost to increase. On average, inspections can cost as much as $550 or more in these cases.

Here is a look at the cost of a basic HVAC inspection for different types of systems:

Air Conditioner

Regular inspection and maintenance of an air conditioning system are necessary for keeping it in optimal working order, especially in the summer when you need it most. If not properly maintained, the air conditioner can become inefficient, possibly leading to more frequent repairs and an increase in energy bills.

The cost of inspecting an AC unit depends on its size, type, and age. Typically, an air conditioner inspection costs about $100 to $150, not including any repair costs. Note that prices may be higher if any components need replacing or the AC has been idle for a long time.

Some of the main tasks an HVAC professional will perform during an AC system inspection include:

Checking the thermostat settings

Examining the condenser and evaporator coils

Testing the air blower

Inspecting the electrical connections

Checking refrigerant levels and pressure readings

Checking safety devices and controls

Providing repair or replacement recommendations

During the inspection, the technician may also undertake tasks such as cleaning the motor and other system components, lubricating the moving parts, or replacing air filters.


Furnaces are essential for keeping homes warm and cozy in the cold months, but they need regular checkups to keep running smoothly. A typical furnace inspection will range in cost from $75 and $150, depending on the furnace type, your home’s size, and other factors.

Typically, heating system services will include an inspection of the burners, filters, fans, and other furnace components in their maintenance packages. 

Here is a short list of services that are usually included in a furnace inspection:

Inspect burners and combustion chamber for proper operation

Check filters

Check for any carbon monoxide leaks (only gas and oil furnaces)

Examine all electrical components for proper operation

Test the thermostat for accuracy and proper function

Inspect the flue system for proper venting

Check the air ducts and registers to ensure they are not blocked or leaking


When inspecting boilers, it pays to take the right precautions. By ensuring all components are working properly, you can avoid costly boiler repairs down the road and ensure safety at all times. Usually, this boiler inspection will set you back between $100 and $250, but more complex systems may cost more.

The technician will examine your boiler, ensuring there are no leaks and that water and fuel levels are adequate. Additionally, the tech will take a look at the pressure-relief valve and make sure there aren’t any combustion or ventilation issues. Otherwise, hazardous gases could be released into the air.

Heat Pump Inspection Cost

Heat pumps are an efficient and reliable type of HVAC system for your home, delivering both heating and cooling. To keep your heat pump running smoothly and save money in the long run, you need to get it inspected regularly. 

On average, a heat pump inspection costs between $100 and $250. HVAC inspectors look at the refrigerant levels, electrical connections, filters, fan motor, plumbing connection, and condition of the components. Plus, the technician checks for any leaks and adjusts the thermostat.

Air Ducts

Air ducts play an essential role in your home’s HVAC system, working to circulate air and maintain a comfortable temperature. Regular inspections ensure your system is working efficiently and there’s no contamination entering the house via the ducts. 

On average, air duct inspections cost between $80 and $150 and generally take an hour or two. The pro will examine both the inside and outside, measuring air pressure and removing the dirt out of the ducts. The technician often will use specialized video technology to check for any damage or contaminants. If anything needs repairs, that will add to the final bill. 

Supplementary HVAC Units Inspection

A regular inspection of secondary HVAC units may not always be part of the plan, but it’s crucial to check these every now and then. This can keep supplemental HVAC systems running smoothly and ensure they are in proper working order.

Attic fans, air handlers, roof ventilators, and radiant flooring are just a few of the items that might need further inspection. On average, these inspections usually cost between $80 and $250. The tech will inspect fan blades, motors, and electrical connections to spot any wear or damage.

HVAC Unit Average Cost
Roof Vent$80 – $150
Attic Fan$75 – $100
Radiant Flooring$100 – $125

Other Factors That Affect Cost

Besides the HVAC system type and size, many other factors will affect the cost of an inspection. For instance, labor and travel costs can add up. If the HVAC system is difficult to access or requires testing equipment or special tools, this could increase the price, too.

Labor Costs

The labor cost for an HVAC inspection comes down to how complex the job is. A basic inspection can usually be completed in just an hour or two, while more involved inspections could take up to four hours. Your HVAC technician will likely charge by the hour, anywhere from $60 to $150, on average. Plus, keep in mind that there might be additional fees for any cleaning or filter replacement, as well as costs for materials.

Travel Fees

Sometimes, HVAC professionals charge extra to travel to a remote location. This fee will typically depend on how far they need to travel. Generally, you can expect to pay about $25 to $50 for each trip.

HVAC Inspection for Homebuyers

For those looking to buy a home, it’s important to have the HVAC system inspected before signing any papers. An HVAC inspection can help identify potential system issues before committing to the purchase. It can also provide peace of mind that the heating and cooling system will be reliable and efficient for years to come.

Depending on the size and complexity of the system, an HVAC inspection can cost between $100 and $550. This fee usually covers the cost of labor, travel fees, and any additional services that may be needed.

Following the HVAC inspection, a technician may recommend additional services to ensure your HVAC system runs optimally and safely. These could include regular checkups, filter replacements, repairs, or upgrades.

HVAC Maintenance Services Cost

Regular maintenance helps to keep your HVAC system running efficiently, preventing costly repairs and energy waste. On average, HVAC maintenance services cost from $85 to $170, depending on the type of system you have in your home and its size.

Some HVAC contractors offer packages that include seasonal tune-ups and discounts on parts and labor. Typically, this coverage ranges from $150 to $500 a year, but prices vary by company.

Here are some of the services typically included in a maintenance package, along with their associated costs:

Service TypeAverage Cost
Changing Air Filters$10 – $40
Evaporator and Condenser Coil Cleaning$80 – $380
