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.

Here’s how AC professionals will clean your AC coils:

1. Unplug the AC unit or turn off the breaker to the unit in your circuit breaker box.

2. Remove the faceplate.

3. Spray a vacuum hose attachment or compressed air can to remove debris, dust, dirt, and grime.

4. Use a soft-bristled fin comb to remove stubborn caked-on debris.

5. Use the vacuum hose to suck up any extra debris.

6. Take a coil-safe cleaning solution and spray it onto the coils. Try to choose a no-rinse solution.

7. Let the solution sit for at least 15 minutes.

8. Gently wipe away loosened grime and debris with a microfiber cloth.

9. Reattach the faceplate, plug in your AC system, or turn the breaker back on.

When your HVAC system is loud, a few different causes are possible. If you have loose connections or bolts in the hardware, they can rattle as the system runs and vibrates. If you have an extremely dirty furnace filter, it could cause the system to generate noise. More commonly, an excessively loud HVAC system indicates a malfunction in the system. You may have a blower motor that is close to failing or a compressor that is breaking down. These issues require an immediate inspection.

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.
