Q: Can running AC too cold cause mold?

• <div><p>Yes, running your air conditioning unit too cold can cause condensation in the air ducts and built up moisture on the air filter, resulting in a breeding ground for mold and mildew. Mold and mildew growth can irritate those with respiratory issues, so it&rsquo;s best to keep your AC running at a normal temperature.</p></div>

Q: How much does it cost to hire an HVAC technician for maintenance?

• <div><p>The cost of annual maintenance depends on the type of HVAC system you have. AC service <a href="https://www.angi.com/articles/ac-service-cost.htm">typically costs an average of <b>$200</b></a> but ranges from<b> $100 to $550</b>. If your system needs repairs, the price will vary significantly depending on what needs fixing. However, addressing the issues as they arise can prevent further damage to your unit and keep it operating efficiently for much longer. </p></div>

Q: What kind of refrigerant does my HVAC system use?

• <div><p>Some HVAC systems tend to use R410A refrigerant, although if you have an older model <a href="https://www.angi.com/articles/what-fair-price-r-22-refrigerant.htm">it may be using R22</a>. R22 is banned due to its harmful environmental and health impacts, and it is a sign that your AC unit is old enough to consider a replacement and the significant efficiency gains that could come with it.</p></div>

Q: Do I need a ductless unit in every room?

• <div><p>No, you don&rsquo;t need a ductless unit in every room. Ductless AC units don't work the way that window units do, where the air doesn't travel outside that room. The indoor air handlers all attach to the outdoor condenser. While the air doesn't travel the way that traditional ductwork would, the ductless AC units create zones so that one part of the home can be cooler than another. They can spread effectively enough that indoor units only need to be placed in main living areas.</p></div>

Q: Does homeowners insurance cover replacing AC units?

• <div><p>In most cases, homeowners insurance will cover an AC replacement if it was damaged due to a covered peril&mdash;such as theft, fire, or storms. So, if your air conditioner needs replacing due to regular wear and tear, your insurance company probably won&rsquo;t pay for a new one. However, <a href="https://www.angi.com/articles/does-home-warranty-cover-hvac.htm">home warranties often cover HVAC repairs</a> and replacements. </p></div>

Company A said my compressor was almost ready to short out and that I needed a new AC. Not prepared to accept that BS as an answer, I called Straight Shooter. He came out and replaced an intermittent relay, getting me back from limping along to full AC, in a couple of hours.

"Bob Jenson sent 2 installers to put in 3 more mini splits this past Monday. Tony Guardarrama and Pouria arrived on time both Monday and Tuesday. They did an excellent job and I am very satisfied. It was not an easy installation, but they somehow managed to get it all done and no messes were left behind. I wholeheartedly recommend Bob Jenson AC & Heating."

"Michael was knowledgeable and very informative. The installers were competent, outstanding, and courteous. Aire Care’s bid was more budget friendly compared to other major local companies. The crew promised to get installation done in 2.5 days but completed the work in 2 days with an additional install. All in all, we would go with AireCare Heating and Air any day.

"Pat and Tom installed a 5 ton heating and AC unit in my garage/workshop, last summer, and now I can make saw dust 7/24 all week long. Their work was exceptional. Service after installation was done without question. Pat replaced a part in my electrical panel that was defective. Professionalism, installation was exactly what I needed, based upon the size of the garage/workshop area I work in. Service after installation was right on.

Air Conditioning questions, answered by experts

Yes, running your air conditioning unit too cold can cause condensation in the air ducts and built up moisture on the air filter, resulting in a breeding ground for mold and mildew. Mold and mildew growth can irritate those with respiratory issues, so it’s best to keep your AC running at a normal temperature.

The cost of annual maintenance depends on the type of HVAC system you have. AC service typically costs an average of $200 but ranges from $100 to $550. If your system needs repairs, the price will vary significantly depending on what needs fixing. However, addressing the issues as they arise can prevent further damage to your unit and keep it operating efficiently for much longer.

Some HVAC systems tend to use R410A refrigerant, although if you have an older model it may be using R22. R22 is banned due to its harmful environmental and health impacts, and it is a sign that your AC unit is old enough to consider a replacement and the significant efficiency gains that could come with it.

No, you don’t need a ductless unit in every room. Ductless AC units don't work the way that window units do, where the air doesn't travel outside that room. The indoor air handlers all attach to the outdoor condenser. While the air doesn't travel the way that traditional ductwork would, the ductless AC units create zones so that one part of the home can be cooler than another. They can spread effectively enough that indoor units only need to be placed in main living areas.

In most cases, homeowners insurance will cover an AC replacement if it was damaged due to a covered peril—such as theft, fire, or storms. So, if your air conditioner needs replacing due to regular wear and tear, your insurance company probably won’t pay for a new one. However, home warranties often cover HVAC repairs and replacements.
