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 often do HVAC systems need maintenance?

• <div><p>You should have your HVAC serviced at least <b>once per year</b>. A HVAC pro can perform maintenance twice a year if your unit is older or has many issues. You can expect to pay between <b>$100 and $550</b> for <a href="https://www.angi.com/articles/ac-service-cost.htm">HVAC maintenance</a>, which includes a thorough tune-up, routine service, proactive and reactive maintenance, and emergency maintenance services. </p></div>

What are the symptoms of dirty AC coils?

• <div><p>There are several tell-tale signs that your AC coils need cleaning, including:</p><ul><li><p>You’re getting higher electricity bills.</p></li><li><p>Your home doesn’t feel as cool as it usually does.</p></li><li><p>Your AC unit is running longer than usual to cool your home.</p></li><li><p>Your home is more humid than usual.</p></li><li><p>The coil is covered in frost while running.</p></li></ul><p></p></div>

Prompt estimate, fair price, met schedule, they even came out and fixed a funny noise months later. Best hvac service I’ve received in a half century. I’ve spent a career in facilities and construction—they are the absolute best.

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.

Hard working young man who was working under adverse weather conditions. I paid in cash and he is so honest that in counting out the money, I overpaid and he returned the overpayment. Very pleased with the end results of the yard cleanup.

"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"
