Is it better to repair an AC or replace it?

• <div><p>Repairing an AC unit is usually more cost-effective than replacing it, but you should consider the age of your system. Most central AC units last around <b>15 years</b>, and window units last for between eight and 10 years. If your central AC is more than 10 years old or your window AC is over six years old, you should consider <a href="https://www.angi.com/articles/it-time-repair-or-replace-my-air-conditioner.htm">replacing the AC unit</a> rather than repairing it. The repair will fix your issue, but you’ll likely save money in the long run by replacing it rather than repairing it only to replace it a few years later.</p></div>

What is the most common rule used for HVAC load calculation?

• <div><p>A common HVAC rule is that for every 500 to 600 square feet of living space, you need 1 ton of heating or cooling capacity. Now that you know this common rule, you also need to know that it isn’t very accurate, and a dedicated pro wouldn’t use it for your home. If you talk to a pro who won’t or can’t perform a proper Manual J calculation, consider hiring someone more thorough.</p></div>

How do professionals clean AC coils?

• <div><p>Here’s how AC professionals will clean your AC coils:</p><ol><li><p>Unplug the AC unit or turn off the breaker to the unit in your circuit breaker box.</p></li><li><p>Remove the faceplate.</p></li><li><p>Spray a vacuum hose attachment or compressed air can to remove debris, dust, dirt, and grime.</p></li><li><p>Use a soft-bristled fin comb to remove stubborn caked-on debris.</p></li><li><p>Use the vacuum hose to suck up any extra debris.</p></li><li><p>Take a coil-safe cleaning solution and spray it onto the coils. Try to choose a no-rinse solution.</p></li><li><p>Let the solution sit for at least 15 minutes.</p></li><li><p>Gently wipe away loosened grime and debris with a microfiber cloth.</p></li><li><p>Reattach the faceplate, plug in your AC system, or turn the breaker back on.</p></li></ol><p></p></div>

Excellent service! Very professional. This is the second time Wayne has repaired my AC unit. Last year he replaced a switch or compressor on the unit. He came out within 24 hrs to get my unit up and running. Will definitely use him again.

"My experience with Pierce was outstanding from start to finish. When my AC went out during the worst heat spell of the year, I was honestly stressed and worried about finding someone who wouldn?t overcharge me or cut corners. From the moment I called Prolific Construction, Pierce was responsive, kind, and honest. He took the time to listen to what was going on before he even showed up, which already told me he cared about doing things thoroughly. When he arrived, he was right on time?no waiting around for a vague window. He got straight to work, explaining what he was checking and why in clear, simple terms that made me feel informed and empowered. I never once felt like I was being upsold on anything I didn?t need. Pierce is one of those rare professionals who values transparency, and that?s so refreshing. He found the problem quickly and had the parts ready to fix it on the spot. My house was cooling down before he even left the driveway. Prolific Construction will take care ofyou"
