Heating and Air Conditioning questions, answered by experts

If you don’t clean your AC coils, dirt and debris build up inside your unit, making transferring heat more difficult. As a result, your HVAC system will work harder to run, potentially increasing your energy usage and utility bills. Neglected coils may also become corroded, which can lead to refrigerant leaks and mold growth—both of which can cause a slew of negative health impacts.

Replacing an evaporator coil costs around $1,350 on average. The coil itself, depending on the size and brand, can cost from $550 to $1,100. Professional labor averages about $700 total. Note that a license is required to work with refrigerants, so it’s necessary to have an AC pro complete this task.

Definitely. Both experts and homeowners can attest to the convenience and efficiency of HVAC zoning. Not only does it make every room the perfect temperature—no matter what the temperature is for you—but it also saves energy (and therefore money) in the process. It is a costly up-front investment, but many homeowners agree that it’s worthwhile in the long run, especially if you plan to stay in your home for a while.

NATE (North American Technician Excellence) certification is not legally required for HVAC technicians in most areas, but hiring a professional with this certification is highly recommended. NATE-certified technicians demonstrated their expertise and proficiency in different types of HVAC systems, offering assurance of quality service. It's a voluntary certification, yet it indicates a commitment to professionalism and ongoing training. Choosing a NATE-certified technician often means you're working with someone who is up-to-date on industry standards and best practices, which can lead to better service, energy efficiency, and long-term cost savings.

Yes, it’s best to turn off an AC unit that’s blowing hot air to prevent system damage and avoid expensive energy bills. If you let the AC continue running, it will put more strain on the condenser coil and compressor. Plus, if the AC is blowing hot air because of a refrigerant leak, it can also lead to a frozen evaporator coil.
