Heating and Air Conditioning FAQs, answered by experts

An AC drip pan may stop draining if there’s a clog where the drip pan connects to the drain line. Clogs can form from a lack of cleaning or from rust or corrosion buildup. Cleaning the drip pan at least once per month lowers the chances of debris clogging the drain line.

Your AC might not cool after a power outage because of a tripped circuit breaker, blown fuse, or damage to the compressor or capacitor. If you notice your AC not working after a power outage, in most cases, the breaker has tripped or the system has built-in brownout and blackout protection. Reboot the AC by turning it off at the thermostat, resetting the circuit breaker, and waiting 30 minutes to turn the AC on again. 

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.

A calculation method that your HVAC contractor will use to ensure your system does what it's supposed to is measuring duct output, or its CFM. The calculation requires knowing the cross-sectional area of the ductwork and determining the air speed past any given point within it.

The cost to replace an AC evaporator coil is typically between $600 and $2,500, with an average cost around $1,300 to $1,350. The price of the coil itself can range from $550 to $1,100, depending on the brand, size, and style, with professional labor adding around $700. Replacing a condenser coil is generally less expensive, costing about $800. Because this repair involves handling refrigerants, it requires a licensed AC professional. Regular inspections, which cost between $200 and $600, can help prevent costly coil replacements.
