Q: What kind of cover should I use for my AC?

• <div><p>You should use a breathable, weather-resistant cover with ventilation. It can be a top cover or a full cover that has mesh to allow airflow. A full, non-breathable cover can cause moisture to build up, leading to rust, frozen parts, and corrosion. A full cover also attracts unwanted critters, such as mice, that can damage the wiring and your unit. If you need to protect your AC unit from falling icicles, choose a sturdy top cover or piece of wood that prevents icicles from damaging your unit.</p></div>

Q: Do window AC units use a lot of electricity?

• <div><p>Window AC units use a fair amount of electricity, but significantly less than central AC systems. Because they are more energy-efficient for cooling individual rooms or small spaces, their usage is comparatively low. On average, a window AC unit consumes between 500 and 1,400 watts, while a central AC system uses over 3,500 watts&mdash;meaning a window unit uses about one-third of the energy. This typically translates to a monthly running cost of $15 to $40, although this can vary depending on external factors.</p></div>

Q: Are all HVAC Schrader valves the same?

• <div><p>As mentioned above, not all HVAC Schrader valves are necessarily the same. While the valve core and pin or spring size on Schrader valves used for HVAC are generally similar, the valves are not all universal and interchangeable. The size of Schrader valves varies depending on whether it's used in an air conditioner, bicycle tire, or motor vehicle tire.</p></div>

Q: What size window AC do I need?

• <div><p>The size window AC you need depends on the BTU and the size of the room you&rsquo;re cooling. For a room with 8-foot ceilings, look for about 20 BTU per square foot of the room. For example, a 12-by-12-foot room should have an air conditioner with 2,880 BTU. You can buy something slightly more powerful, but don&rsquo;t overshoot the BTU for a small room, or you&rsquo;ll waste energy and have higher bills.</p></div>

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>

"I am so happy that I hired Modern Air! Prompt, courteous, friendly, professional, knowledgeable. I couldnt have asked for better. Tom is a wonderful person in addition to his work ethics. I am never going to use anybody else from here on out. He doesnt try to up sell you or get you to get on their contract program and, he finds the problem and addresses that . In this record heat and being a Saturday didnt deter him I am blessed to have found Tom with Modern Air. He repaired my ac unit. Hallelujah! My unit is only 3 yr old but the idiot company that installed it did it improperly, didnt register it, left all kinds of debris in attic and would NEVER service it. All they want is $$$for new install and leave you hi n dry. Do not use Joe Hope Fl. West Coast A C!! I had to have the ac unit replaced in another house and I called Modern A C again in August of 2020 He is amazing! He came quickly and tore out old and installed new. Very professional. Got a permit. Registered unit. Very clean. Did everything the way it should be and at a reasonable price. I highly recommend"

"Ken found that our AC had a lot of mold which was impacting the air flow through our ducts. He made several suggestions, cleaned the system and installed ultra violet items to mitigate the mold and keep the ducts clean. He was extremely easy to understand and showed us everything that he did. He also did a few minor fixes on our vents. I would definitely use them again."

"We had Fontana Bros. replace our complete HVAC system. They were professional, reliable and easy to work with. They coordinated flawlessly with our condominium association. Our HOA required that a crane be used to place the compressor unit on the rooftop and Fontana Bros. handled all the details skillfully.

Air Conditioning questions, answered by experts

You should use a breathable, weather-resistant cover with ventilation. It can be a top cover or a full cover that has mesh to allow airflow. A full, non-breathable cover can cause moisture to build up, leading to rust, frozen parts, and corrosion. A full cover also attracts unwanted critters, such as mice, that can damage the wiring and your unit. If you need to protect your AC unit from falling icicles, choose a sturdy top cover or piece of wood that prevents icicles from damaging your unit.
