Reviewed by After Hours Home Improvement, LLC, Reid Gravitte, Certified Electrician, Plumber and HVAC Specialist.Most homeowners pay between $166 and $600 in AC repair costs. Prices for this project vary greatly by issue, part, project complexity or company. Be prepared to pay upwards of $450 to $1,000, depending on your repair.
The cost per hour can be anywhere from $35 to $200. Keep in mind that many contractors calculate rates based on the job, and not hourly labor. For example, repairs to a small window AC unit will probably cost less than fixing a central ac system.
You can DIY many repairs to your air conditioning unit, but it is best to let a pro take care of any projects involving Freon. A licensed professional should deal with this dangerous substance.

If you notice any of these signs, there’s a chance that your air conditioner is malfunctioning. Call an AC repair pro in your area to diagnose and fix the problem.
First, make sure the thermostat is set to “cool.” Then, confirm that your designated cooling temperature is less than the temperature of the room or home. If everything appears to be in good shape, examine the electrical panel to be sure you do not have a tripped breaker. If nothing appears to be out of place and the unit is still not working, get in touch with an air conditioning professional.
If your thermostat is set to a reasonable temperature and your home is still uncomfortably warm, your air conditioner is not doing its job correctly.
You are likely familiar with the typical noises your unit makes as it cycles. So, when you hear something that sounds off or different, it is time to call for repairs.
Unusual odors coming from your unit indicate there is dirt, mold or mildew inside. This can circulate contaminated air through your home. Bad smells are more than just a nuisance. They indicate a problem that should be addressed right away to avoid health issues for your family.
It is perfectly normal for your air conditioner to cycle on and off to maintain a set temperature throughout your home. However, if you notice that it is turning on and off more frequently than usual for no apparent reason, then it is possible that your unit is malfunctioning. Short cycling puts extra stress on your air conditioner and can cause it to fail if not handled quickly.
While a small amount of condensation is normal, excessive water in your unit indicates problems. Contact an HVAC repair professional for help. This job involves electrical components that should be left to the pros.
Ice or frost in your air conditioner is problematic. Blocked or restricted airflow causes ice buildup which can cause your unit to freeze. It can also lower Freon levels, requiring a unit recharge.
Though a broken AC may continue to work for a time, it’s best to get any problems fixed as soon as possible. Ignoring warning signs can make a small problem worse and cause more expensive repairs in the long term. Have your unit repaired promptly to avoid major damage or a high utility bill.
An experienced DIYer should be able to take care of many small repairs. However, it’s best to call a pro if there is electrical work involved. And you should definitely ask for help if the project involves working with refrigerant, which is a toxic material that often requires a license to handle.
Be sure to do your homework before hiring a professional service. You’ll want to check:
State licensing and insurance requirements.
Your HVAC system’s history and any warranties. The average manufacturer's warranty is 5 years.
Prices and service packages from different contractors.
Referrals from friends and family.
Professional certifications, associations and partnerships. Including but not limited to:
Air Conditioning Contractors of America (ACCA)
Sheet Metal and Air Conditioning Contractors’ National Association (SMACNA)
Certified by North American Technician Excellence (NATE)
Partnered with ENERGY STAR
Try to stick with a company that specializes in HVAC services. While some general handyman companies can provide a low-cost alternative to many projects, a company that focuses on air conditioning and heating is usually a better option. Take a look at this guide for more tips on hiring a contractor.
Are they licensed, bonded and insured?
Are their technicians certified by any professional HVAC organizations?
What types of warranties and guarantees to do they offer for their work?
If your unit is still under warranty, is the HVAC pro certified to do warranty work for the brand of AC you own?
If there is a “free” offer, are there conditions you must meet to qualify for it?
How many years has the company been in business?
Will they provide testimonials and references for you to review?
Does the HVAC repair company require their employees to undergo background checks and drug testing?
Does the company provide an AHRI Performance Certification? This is only required for commercial units.
Will the technician inspect the duct system as well as the unit itself?
How does the company charge for services?
Is financing available for larger repairs?
Does the company have a 24/7 emergency ac repair service?
Will the company provide a written estimate before starting the work?
AHRI Certification
Your HVAC professional can provide you with an AHRI Certificate of Certified Product Performance upon request to help you verify that your system is properly matched. The certificate verifies that the Air Conditioning, Heating and Refrigeration Institute (AHRI) has certified your outdoor unit (condenser) and indoor unit (evaporator) combination as a matched system. This is only common and required for commercial spaces, not residential.
For higher efficiency models, this certification may help you obtain a rebate from your utility or local municipality. Not all areas offer a rebate, but your technician will likely be able to provide information about the certification process. Fees for performing this certification vary, but are generally very expensive. Talk to your local HVAC professional to see if the cost is rebate is worth the cost of the certification.
EPA 608 Certification
The Environmental Protection Agency (EPA) requires that technicians who work with controlled refrigerant carry certification to do so. There are four levels of certification. Your HVAC technician should be “level two certified” at a minimum. Being “universal certified” is even better. It’s a good idea to obtain this certification information from your HVAC technician. You may need it in the future if you decide to sell your home. Costs for certification average $40 to $240.
The average cost to replace a central air conditioner is about $5,000. But it can be as much as $12,500 depending on the size of your home and how complicated the ductwork is.
Generally, an AC lasts between 12 and 15 years. But this number varies depending on how often you use the unit. The more use the system gets, the faster it will wear out. After 15 years, it’s a good idea to call an AC installation professional for a new unit.
Freon itself can be very dangerous. But a normal leak in your home shouldn’t hurt you as long as you exercise caution. Avoid the refrigerant and make sure the area around the leak is well-ventilated. Do not directly inhale the gas and make sure to stay away from the leak if it is in an enclosed space. Too much exposure can lead to refrigerant poisoning and even death.
It costs between $100 and $60 to put Freon in a central air system. The price varies based on the size of your unit and the type of refrigerant you use.
The cost to find and fix an AC leak is between $225 and $1,600.
