Q: How long does it take to fix an air conditioner?

• <div><p>Most AC repair technicians will take between <b>two and six hours</b> to carry out repairs, depending on the work needed and the accessibility of the unit. For example, recharging refrigerant lines should take one to two hours to service, while replacing a compressor, blower fan, or other major components can take five to eight hours. You can ask your AC repair technician how long they expect the job to take, but just in case, you should plan on being home and available for most of the day.</p></div>

Q: How much does it cost to repair an air conditioner?

• <div><p>The cost to repair an air conditioner averages around $350 to $450, but the price can range from $100 to over $3,000. The final cost depends on the type of air conditioner, the extent of the damage, and the specific parts that need replacement. For example, repairing a window AC unit typically costs between $100 and $250, while central air conditioner repairs can range from $300 to $3,000. A simple fix like replacing a dirty filter might only cost $10 to $50, but a major issue like a broken compressor could cost around $2,000 or more, potentially making it more cost-effective to replace the entire system. Due to the need for specialty tools and handling of refrigerants, repairs more complex than changing a filter are best left to a professional.</p></div>

Q: How often should I clean my air conditioning unit?

• <div><p>You should clean your air conditioner at least once per year, but you may need to clean your whole HVAC system (including the air ducts) more often. According to the <a href="https://nadca.com/homeowners/frequently-asked-questions">National Air Duct Cleaners Association</a>, you may need to clean them more frequently depending on factors like whether you smoke, have pets, or have allergies.</p></div>

Q: How much does it cost to replace an HVAC system?

• <div><p>The average cost to replace or install a new HVAC system is around $7,500. However, the price can range from $5,000 to $12,500, depending on factors like the size of your home, the type and brand of the unit, and your specific heating and cooling needs. If you only need to replace certain components, the cost will be lower; for example, a new AC unit can cost between $2,200 and $5,500, while a new furnace costs $3,200 to $6,000. If additional work like new ductwork is required, the total cost could be as high as $22,000. It's best to contact a local HVAC company for an accurate quote.</p></div>

Q: How do I protect my air conditioner in the winter?

• <div><p>You can protect your air conditioner in the winter by turning off the power at the thermostat and performing <a href="https://www.angi.com/articles/8-spring-air-conditioning-tips.htm">routine HVAC maintenance in the spring</a>. Regular maintenance, cleaning, and repair of your AC unit helps protect it and extend its life span. If you have a window AC unit, remove it from the window and store it in a dry place during the winter. Window units cannot withstand freezing temperatures. Keeping them in your window also allows cold air to seep into your home. </p></div>

"They didn't come on time at all. The issue I had was that they had a price advertised for a system check and when they came they said that I had two different air conditioning units and it would be two different prices. I felt that was a bit misleading and they didn't say that when I called to make the appointment. The guy that came was fine. He was great. I was happy with the service. I just felt mislead."

After he took care of the dryer vents, I asked if he could take a quick look at the fan/exhaust in one of my bathrooms and let me know if I could schedule a later date to have those cleaned. Not only did Kevin take a look, but he cleaned them with a smile and no extra charge. Kevin, with Appalachian Air Ducts, is a true professional and I will absolutely hire them in the future!"
