"Floyd with Ducts Columbia is now the only company I will use for duct cleaning, sealing vents, & dryer vent cleaning. His level of care and detail completing my project left us feeling like we were taken care of by family. He asked my questions, addressed concerns, and educated me in areas where it was important for ongoing safety and health. If I could rate higher than 5 stars I absolutely would."

"One of my AC units was not working correctly so as always I went to Angi to find someone qualified to do the work. CALL DAD HVAC called me right away and said they could come out that afternoon but due to my schedule had to wait until the next morning. Daniel arrived here promptly and worked all day until all the work was completed to my satisfaction and approval. I was so pleased with the work I decided to sign up for a year's contract with them which was very reasonably priced. If someone needs any HVAC services/repairs I highly recommend CALL DAD!"

Air Conditioning FAQs, answered by experts

Fixing a leak in an AC unit costs $200 to $1,600, depending on the type of leak and any related damage. But depending on the age and condition of your AC, it might make more sense to replace the AC unit instead of repairing it. If your AC is only a few years old and relatively problem-free, then repairing it is the right call. But if it’s nearing a decade old and has other issues, consider replacing it.

An air conditioner’s watt usage depends on multiple factors, including the type of AC unit, its size, and how often you use it. With that said, most central air conditioners consume between 3,000 and 3,500 watts. Meanwhile, window AC units use 900 to 1,400 watts, and portable air conditioners consume 2,900 to 4,100 watts.

Setting your AC unit to 78 degrees can, indeed, help you save energy. In fact, according to experts, every degree you turn the unit up could save you between 1% and 3% on your energy bills. That said, turning your unit off entirely while you’re out might actually be less efficient than keeping it on at a higher temperature. Why? The unit will need to work extra hard to cool the house back off again after all those hot hours. 

To find a reputable HVAC company, start by researching providers in your area. Look for companies with mostly positive online reviews and check the Better Business Bureau’s website for customer complaints. Next, verify their credentials. Rule out any companies that aren’t licensed, as this is a requirement in some states and municipalities, and confirm they are insured. Once you have a shortlist, contact each professional to ask key questions: How many years of experience do you have? Do you hold any third-party certifications? Do you have experience working on my specific type of HVAC system or brand? Can you provide references? What is your per-hour pricing? Do you offer maintenance contracts for ongoing savings? Do you provide a warranty for your work?

Yes, having mismatched evaporator and condenser coils in your AC system can lead to serious issues. For instance, it can result in higher monthly energy costs as the system runs longer to compensate for the mismatch. This mismatch can also put extra stress on the system, compromising its efficiency and longevity. 

Along with that, mismatched coils can lead to higher temperatures and humidity levels in the home. What’s more, using coils of different sizes may violate the manufacturer's warranty, as they are designed to work synergistically, and any mismatch could lead to repairs and system failure.
