HVAC Inspections: What to Expect and Costs

Why Should You Get an HVAC Inspection?

Annual HVAC inspections are an important part of maintaining your heating and cooling systems. Regular inspections not only help your HVAC system run more efficiently, but they can also identify and prevent larger issues down the road. 

During an HVAC inspection, your technician will replace your air filter, clean the system components, lubricate moving parts and check for other problems. This basic HVAC tune-up will keep your system running efficiently and prevent breakdowns. 

How Much Does an HVAC Inspection Cost?

A routine HVAC inspection will typically cost you $75–$150. That being said, the size and type of equipment you have can drive these prices up. 

Hiring a professional to inspect your equipment can extend the life of your HVAC system. Regular inspections may seem like an unnecessary expense, but they are far cheaper than an HVAC replacement, which typically costs between $5,000 and $10,000. 

What Does An HVAC Inspection Entail?

Most HVAC systems have several units. In most cases, your HVAC system will include a heat pump or separate air conditioning and furnace units. These systems have indoor and outdoor components, as well as ductwork throughout the walls of your home.

It’s best to have your heating system inspected in early fall and your cooling system inspected in the early spring in preparation for each season. Alternatively, you can have your entire system inspected once a year. You should also have your HVAC inspected if your HVAC warranty is set to expire soon. 

Before your inspection, discuss the process with a licensed HVAC technician. They can give you individualized advice on how to maintain your system and how frequently it needs to be serviced.

Furnace Inspection Checklist

When inspecting your heating system, your HVAC technician will perform basic safety and performance checks: 

• Calibrate thermostat
• Inspect safety controls 
• Test for gas and carbon monoxide leaks 

Your technician will also inspect these components of your furnace for signs of damage, age, or defects: 

• Furnace cabinet
• Electrical components 
• Blower wheel
• Ignitions
• Exhaust Venting
• Heat Exchanger

Air Conditioning Inspection Checklist

When inspecting your air conditioner, the most important components that your HVAC technician will check are: 

• Refrigerant levels
• Electrical connections 
• Evaporator Coil
• Drain Pan
• Condensation Line
• Outdoor condenser & blower fan

Airflow Inspection

An airflow inspection can help improve the air quality in your home and improve the efficiency of your air conditioning. During an airflow inspection, your HVAC technician will check for duct leaks and test for proper airflow. 

These inspections will help you identify issues with your air conditioning system that could be hindering airflow. That includes dirty air filters or cracked or blocked ductwork. 

After Your HVAC Inspection, What to Expect

After your HVAC technician has completed the entire inspection checklist for your particular HVAC unit, they will create an inspection report.

HVAC contractors create inspection reports to record important details about the state of your HVAC and recommend further action, if necessary. 

For instance, if you need an HVAC repair beyond what they can easily complete during the inspection, your HVAC contractor will detail what your next steps should be in the inspection report. 

If your HVAC technician determines that you need further repairs or an HVAC replacement, set a new time and date to have a technician return and complete the necessary work,

Common Problems Found in HVAC Inspection

Routine HVAC inspections can uncover any number of issues with your HVAC system. Because your HVAC units have so many components, there are many things to look out for. Here are some of the most common problems HVAC technicians find during HVAC inspections: 

• Gas line leak: A cracked heat exchanger or other damaged equipment can cause a leak in your furnace’s gas line. This can be a result of poor airflow to your system, which can be prevented with regular maintenance. 
• Exhaust venting problems: Snow, leaves, branches, rust or other damage can block your furnace’s exhaust vent. This can stop your furnace from heating or shut your system down entirely. You could also be at risk of carbon monoxide poisoning if this issue is left unresolved. 
• Dirty or clogged filters or evaporator coil: If your evaporator coil or air filters are dirty or clogged, your HVAC will be working inefficiently. Air will be drawn through slowly and with more difficulty. 
• Cracked or leaky ductwork: Cracked ductwork is the fastest way to lose a significant amount of air in your HVAC system, drastically reducing the efficiency of your system. 
• Faulty wiring: Faulty wiring in your HVAC can trip your breaker and cause your system to keep shutting off. Electrical issues can cause significant damage if left unattended. 
• Undercharged or overcharged refrigerant: Too much or too little refrigerant will prevent your AC system from cooling properly. The pressure in your AC will be off-balance, putting strain on your compressor and AC unit. 
• Aging HVAC system: If your HVAC system is getting old and keeps needing repairs, it may be time to replace it. Your HVAC technician can advise you on the best time to do this. 

Choosing an HVAC Inspector

Reputable HVAC companies are well-seasoned experts when it comes to inspections. When you’re deciding which HVAC inspector to go with, we recommend looking for the following:

• Long-standing reputation: How long has the company been in business? Are they known for quality work? A little research can help you determine which companies are dependable. 

• Positive online reviews: Check if the HVAC company you’re considering is BBB accredited and has positive reviews on trusted websites. 

• Local service: Of course, you’ll want to double-check that the company you choose offers service in your area and is qualified to work on the type of equipment you have. 
• Fair pricing: Do your research and call around for information about pricing and services. When comparing prices, consider what is included in the inspection (will they replace your air filters? Will they clean and inspect your HVAC equipment? Will they perform repairs as necessary?).
