HVAC Repair Cost Factors

There are a few things that impact the total cost of your HVAC system repairs. Certain parts are more expensive than others. It typically costs more to replace individual parts than it does to repair them—but not always. Sometimes the opposite is true. Here are the most important cost factors.

Type of HVAC Unit 

The standard HVAC system has two main components—an AC unit and a heater. The heater could be a furnace, boiler, or heat pump. Sometimes, it’s all wrapped into a single package unit (like you see with rooftop ACs or ductless mini-split systems). It just depends, but either way, the type of HVAC unit will impact the cost of repairs.

Labor 

Labor can account for as much as 50% of the project cost. Generally, an initial HVAC service call costs between $100 to $250—but that’s just for your contractor’s assessment. On the follow-up, the tech will either charge a flat fee for specific repairs (which includes the parts and labor) or $100 to $250 per hour on top of the cost of parts.

Location

Different climates have different demands for HVAC systems. This influences the average cost of repairs because the most common repairs are different from place to place. You can also expect to pay more for labor in areas with a higher cost of living.

HVAC Repair Cost Breakdown by Part

When individual components break down, it can cost $100 to $2,000 to fix, depending on the severity of your issue. You could pay up to $7,500 for a full-on AC replacement. Take a look at what you’ll pay for various HVAC repairs.

Additional Costs to Consider

Beyond standard HVAC repairs, homeowners may have to spend on other related costs. This can include things like system replacement, ductwork repair, warranties, maintenance, and emergency repairs. Here are some things you might want to consider adding to your HVAC budget.

Repair vs. Replace an HVAC System

Generally, an HVAC system replacement costs more than repairs, but replacements can be more cost-effective in the long run. You’ll typically want to replace a system if it’s nearing the end of its lifespan (around 10 to 20 years) because ongoing repairs will add up. You should also consider replacing your system if the required repairs amount to more than 50% of the cost of a new AC unit. To get the best value, always weigh the cost of replacing an HVAC system against the cost of expected repairs.

Ductwork Repair

Sometimes your HVAC issue isn’t because of your furnace or air conditioner. It’s actually an issue with your ductwork. In that case, expect to spend somewhere between $500 to $2,000 on ductwork repairs.

HVAC Maintenance Contract

To properly maintain your HVAC unit, you should get an annual tune-up. This HVAC maintenance cost generally falls between $75 to $200, depending on what your contractor needs to do. You could spend as little as $10 to $50 replacing the air filter or as much as $750 to tune up a large AC in a spacious home.

Keep in mind that some manufacturers do require a service contract to maintain your system’s warranty. For most homeowners, HVAC service contracts cost between $150 and $500 per year. 

Warranties

Most HVAC systems come with a warranty. You can also purchase a home warranty. The typical home warranty system plan costs between $360 and $540 per year in addition to service call fees. This type of plan will generally cover your HVAC system, your plumbing, your home’s electricity, and your water heater.

Emergency Repair Fees 

Emergency repairs—which are made after typical business hours—generally cost more than scheduled repairs. The exact price depends on the problem, but an HVAC tech may charge an additional $40 to $80 per hour for this type of work.

Permits or Inspection Costs 

Your annual tune-up typically includes a standard HVAC inspection. If something looks concerning, your contractor may request a ventilation inspection, which checks the electrical system and airflow. Expect to spend $80 to $450 on this type of inspection.

If you need to replace your HVAC system or install new ductwork, you might have to obtain an HVAC permit. This will add $250 to $400 to the cost of your project.

DIY vs. Hiring a Professional

Avoid common HVAC repair mistakes like using quick fixes and skipping troubleshooting methods. Hire a pro to help, instead. Haphazard DIY repairs could damage your system further, causing its efficiency to drop. Also, you’ll void the warranty by trying to DIY.

DIY projects are an excellent way to test your skill set, but HVAC jobs are better off in the hands of a professional HVAC company near you. We know HVAC repairs can be costly, but you’ll have peace of mind knowing the installation was done correctly by local HVAC contractors.

How to Save Money on HVAC Repairs

As a homeowner, saving a buck here or there is high on your list of priorities. Unfortunately, HVAC repairs can hinder those savings and have you wondering if your money is part of a disappearing act.

Yes, some HVAC repairs can be more expensive than others, but there are ways to save money on those costs, such as:

• Buying an HVAC maintenance service contract.

• Changing your filters regularly.

• Keeping the area around your HVAC unit debris-free.

• Replacing unrepairable parts when necessary.
