An HVAC inspection costs $150 to $500. The inspection is crucial to confirm the new system was installed or repaired correctly and will operate efficiently. Inspectors also ensure the system meets the Home Energy Rating System (HERS) testing and verification requirements.

HVAC cleaning cost

Cleaning your HVAC system increases its energy-efficiency and keeps your energy bills down.

  • AC coil cleaning costs $100 to $400 on average. AC evaporator coils should be cleaned at least once per year.

  • HVAC duct cleaning costs $300 to $700 on average or $25 to $45 per vent. HVAC professionals recommend cleaning your air ducts every 3 to 7 years.

HVAC maintenance tips

Perform these basic tasks to keep your HVAC unit well maintained:

  • Replace the filter – Change the filter every 90 days. Consider purchasing new, high-efficiency, pleated filters. They carry an electrostatic charge that grabs the smallest particles before they can enter your system.

  • Maintain a 2-foot clearance around the unit and clear any debris – Ensure proper airflow by keeping the area around the outdoor unit free of sticks, leaves, and grass.

  • Inspect and clean the condenser fan blades – Carefully wipe off the blades to ensure they're free of accumulated dust and dirt. Keeping them clean keeps the air in your home cleaner.

  • Lubricate the condenser fan motor – Look for oil ports and give each one a few drops of SAE 20 to keep things lubricated. Don’t add oil to any place that does not have a port or indication that oil is needed.

  • Shade the compressor unit / Form-fitting cover for winter – Protect the unit from extreme weather with a cover.

  • Clean the indoor evaporator coil, drain pipe, and evaporator trap – Use solvent solution and fin cleaning brushes to gently clean the evaporator coil. Use a pipe cleaner to unblock the drain hole leading to the drip pan.

  • Seal any leaks in the ductwork and consider insulating it all to prevent or reduce condensation.

  • Ensure your thermostat is working correctly, and change the temp according to the season.

Electrical repair components

Learning about all the electrical components in your HVAC system such as a heat pump, fuses, or compressor will help you navigate who to hire and how much the job should be.

  • Capacitors – A capacitor collects and stores energy to start the HVAC system's motors and keep them running smoothly. Capacitors last 10 to 20 years but may require replacement more often in areas that experience extreme temperatures or power surges.

  • Compressor – The AC compressor costs $1,300 to $2,500 to replace. The AC compressor is located in the outdoor unit and is responsible for circulating refrigerant through the system. The compressor changes the refrigerant to a liquid or gas as needed to propel it through the evaporator coil and condenser unit, removing hot air and sending cold air into the home.

  • Contact/Relay – The contact/relay is the switch that turns on the compressor. Over time, the contacts can pit and then and stop working correctly.

  • Furnace Circuit Board – The circuit board is the brains behind the whole operation. If your furnace is stopping and starting continually, the problem could be in the circuit board.

  • Fuses – Fuses are designed to keep the electrical current at a safe level. If the current exceeds a safe level, the fuse breaks the current and trips the circuit breaker. If your furnace or AC regularly trips the breaker, check the fuses.

  • Gas Valves – Valves control the flow of gas in a furnace or liquid gas refrigerant in an AC. Valves can get dirty and become stuck in an open or closed position.

  • Indoor Fan Motor – The indoor blower fan motor keeps the air flowing through the vents and into your rooms.

  • Outdoor Fan Motor – This motor powers the fan that keeps the outdoor unit cool as it runs. Keeping the compressor cool prolongs its life and keeps your home cool. If the motor overheats, it may stop working, which endangers the compressor. If the outdoor unit is warm to the touch, turn off the unit and call an HVAC company.

  • Drain Lines – Drain lines need to be cleaned regularly to remove dust and dirt. Pour 1/4 cup of distilled white vinegar into the condensate drain every month to prevent mold and bacteria. Let it sit for 30 minutes, then flush with hot water.

  • Indoor Coil – The indoor coil works at absorbing the heat from the air in your home. It can become dirty and clogged, but it can be hard to access. The indoor coil may need cleaning if you notice warm air coming from your vents or the system doesn’t work as well as it has been.

  • Outdoor Coil – Also known as the condenser coil, it's located in the outdoor part of your system. As the heated refrigerant arrives, the condenser coil removes the heat to the air blowing over the top of it, and the refrigerant cools again, turning into a liquid, and heads back into the indoor coil to start the process all over again.

  • Refrigerant Metering Device – This part is responsible for sending the correct amount of refrigerant to the evaporator coil. If the metering device malfunctions, the amount of refrigerant used will not be correct and the system will not function properly.

  • Restriction Reversing Valve – These valves typically don't malfunction but may occasionally get stuck or leak. Both scenarios require repair by a qualified HVAC technician.

HVAC repair FAQs

Is It Necessary to Service an AC Every Year?

Yes, for the HVAC system to run efficiently, the AC needs to be cleaned and the filter replaced every year.

How often should you have HVAC serviced?

Have your HVAC serviced at least once per year. An annual visual inspection allows the HVAC technical to spot potential issues before they become pricey problems.

Consider having the AC serviced in the spring and the furnace serviced in the fall.

How long do HVAC units last?

A properly installed HVAC unit lasts 15 to 25 years if it’s well maintained.

Consider installing a new HVAC system if your units are older than 10 years old and the repair bill would be more than 30% of the cost of a new system. HVAC replacement costs $5,000 and $11,000 depending on the size of your home and if you need to replace the ductwork.

Do HVAC technicians give free estimates or quotes?

Most reputable HVAC technicians offer free estimates with an in-person service call. However, beware of companies that give you a free quote over the phone, as it may not accurately reflect what they will discover once they check out the system.

Companies that charge for an estimate typically apply that amount toward your balance due if you hire them to perform the repairs.

Are HVAC service plans worth it?

HVAC service contracts are only worth it if you can purchase one for a reasonable price .Service plans often include priority booking, and many HVAC contractors offer discounts for routine maintenance for customers with an annual plan.

However, you do not need a service plan if you have a new HVAC system that's still under warranty.

Hiring an HVAC repair contractor

HVAC systems are quite complicated, and all the separate parts need to work together seamlessly to be energy efficient. There are a few things you should look for when hiring an HVAC repair service, either for repair or for replacing your system.

  • Confirm they are licensed by the state you live in, and make sure the license is current.

  • They should be bonded and insured for at least $500,000.

  • Look up online reviews on HomeGuide and Google.

  • Choose a company that has been repairing HVACs for at least five years.

  • They should inspect your system to give an honest, accurate estimate.

  • Be sure you’re comfortable with the brand they intend to install.

  • Choose one with a good warranty on labor costs.

  • Ask if this company does background checks on the technicians who will be in your home.
