Q: Is it bad to run AC below 70 degrees?

• <div><p>Most HVAC companies recommend against setting your AC below 70 as it could freeze up the system and cause more problems. Regardless of how hot it is outside, there is generally a 20 degree difference between the outside and inside temperatures, so even if it&rsquo;s 100 degrees outside, your AC will likely not be able to cool your home to 70 degrees. </p></div>

Q: What’s the difference between a home surge protector and an HVAC surge protector?

• <div><p>The difference between a home surge protector and an HVAC surge protector is that an HVAC surge protector is designed to protect the components inside your HVAC unit while a home surge protector is installed near appliances and meant to protect your entire home. There are three tiers of whole-house surge protectors, and they are more expensive to install than HVAC surge protectors.</p></div>

Q: Does a higher SEER AC cool better?

• <div><p>Because of the improved efficiency, ACs with higher SEER ratings tend to cool down your home better than models with a lower SEER. Higher-SEER AC units have a higher cooling capacity and a lower energy demand, meaning they may help cool your space faster without running up the electricity bill.</p></div>

Q: Can heat pumps cool a house in over 100-degree weather?

• <div><p>Yesh, heat pumps can easily cool homes when the weather reaches over 100 degrees Fahrenheit, just as powerful air conditioners can. The key is sizing the heat pump correctly for the size of your home and your climate. A local heat pump professional can help you determine the right size and type for your home. </p></div>

Q: How long is a typical HVAC warranty?

• <div><p>The standard HVAC warranty is around five years. Still, many brands offer an extension to 10 years if you register the product within a specific timeframe, typically 60 to 90 days post-purchase or HVAC installation. Over the past decade, warranty periods have substantially increased, shifting from 3-5 years in the 90s to the now-prevalent 10+ year warranties. Both warranty types cover parts failing due to manufacturer defects, incurring no additional costs. Some manufacturers provide extended warranties surpassing the usual 15- to 20-year window, though these often involve extra fees. </p></div>

"J & J Air, installed our new Trane system a couple of years ago and did a wonderful job. Installation went very well, on a terribly hot day, the team did a great job, with no mess left behind. We have had a couple of Mechanical issues 1 with a broken part, and 1 with a failed switch. Both times the J & J teams showed up on time and resolved the issues as needed. Jeremy and his team are to be commended for their efforts and their Customer Service."

"Quality Air & Insulation installed a complete new heat pump system including all new ducts at my Myrtle Beach residence. From tearing out the old system to installing and balancing the new one, their technicians, office staff and management did a superb job. They supplied temporary conditioning during the week ours was out of service assuring our comfort. The new system is quiet and rated much more energy efficient than the old one, They worked with us to select a system that met our needs and budget and included a year of free maintenance for our several units. If you need HVAC service and equipment, you can trust Quality Air & insulation."

Regardless of how hot it is outside, there is generally a 20 degree difference between the outside and inside temperatures, so even if it’s 100 degrees outside, your AC will likely not be able to cool your home to 70 degrees.

The difference between a home surge protector and an HVAC surge protector is that an HVAC surge protector is designed to protect the components inside your HVAC unit while a home surge protector is installed near appliances and meant to protect your entire home. There are three tiers of whole-house surge protectors, and they are more expensive to install than HVAC surge protectors.

Because of the improved efficiency, ACs with higher SEER ratings tend to cool down your home better than models with a lower SEER. Higher-SEER AC units have a higher cooling capacity and a lower energy demand, meaning they may help cool your space faster without running up the electricity bill.
