"I purchased a Deal, spoke with Ken, the owner, and he was flexible about my schedule changes (due to the tile job taking longer). Since a crew was running behind, he came himself to do the work late in the afternoon knowing that I needed the vent cleaning that day before we moved in. Ken did an amazingly through job of cleaning and disinfecting, and shared his knowledge about HVAC systems and duct routing the whole time. He analyzed our system capacity, checked the duct routing in the attic, and gave us options for improving our HVAC system in future when the existing equipment is ready for replacement. So not just a simple service - an informed future strategy! Can't say enough about how impressed we were with A Breath of Fresh Aire, we will definitely use their services again."

"We are extremely happy with the service we received from this company. Our initial estimates from other companies were prohibitively high and it also seemed that we weren't meeting eye to eye on our expectations. Luke from Matthew Roberts Inc came out to do our estimate and immediately understood what we were trying to accomplish and gave us a fair price. The work was completed in a high quality and professional manner. The attitude and customer service we received was far and away the best out of the 4 or 5 other companies we contacted for this job. We will definitely return to them for our future HVAC needs."

"I called Air One of Central Florida because my AC wasn't working properly. A friend of mine recommended them for their professionalism and competitive prices. They arrived on time and were very professional.They examined the unit and recommended a change out. We agreed on a time and a price. When they arrived to change out the system, they were on time and delivered the service as we agreed upon. There were no hidden fees. They were very personable and polite and great around the kids. They completed the work within one day. Everything was cleaned up afterwards, and everything works well since then. We were very pleased with their service and would highly recommend Air One of Central Florida to everyone -including my friends and family.

"They were very prompt and most importantly I knew that they knew what they were talking about. Had a bad experience with a different HVAC company who was offering a $39.00 tune up as the big deal through Angie's list and ended up having a laundry list of issues that needed attention. Glad I called for a second opinion as Serviceone came out and completely discredited everything that was told to me and actually found the problem that was causing the fan not to spin and the coils to be hot to touch. If I would have went with the other company I would have sent over triple with deep cleanings and replacing fan motors that did not need to be replaced. Not to mention that the capacitor which was the root cause of the issues would not have been dealt with. I would HIGHLY recommend Serviceone to anyone needing tune-ups or repairs on HVAC systems.

"Joe was friendly, responsive, knowledgeable, and prompt! Same day service was super convenient! He cleaned the dryer vents and also replaced my return air vent in the ceiling. Highly recommend and I will be contacting him again in the near future for air duct cleaning and any other HVAC work to be done!"

"Called Wesley For a free estimate on HVAC replacement. It was recommended by another business that I replace the whole HVAC system. Wesley came and looked at it and said absolutely not. He could have easily under cut the competition and made 10k. By far the most honest person I have dealt with since coming to Florida. I will only use Wesley Whitson for all my HVAC needs…"

Heating and Air Conditioning FAQs, answered by experts

Replacing an HVAC system does not always include new ductwork. The decision depends on the condition of your existing ducts. If they are in good shape, correctly sized for the new unit, and meet current standards, they can often be reused. However, if the ducts are damaged, poorly designed, or improperly sized, they will likely need to be replaced or upgraded to ensure the new system operates efficiently. An HVAC contractor will assess your ductwork and recommend the best course of action. Typically, ductwork is purchased separately, and a full replacement will add to the overall project cost.

The outdoor portions of air conditioners are designed to weather the rain, so you don’t need to worry about it. An awning or roof will help protect them from snow or falling debris, which can do more damage. This is true of both window AC and outdoor units for larger systems.

Signs that your air conditioner capacitor is bad or failing include a range of symptoms. The AC unit may not turn on at all, or it might struggle to start before shutting down randomly or in the middle of a cooling cycle. You might hear a humming or banging noise when it attempts to start, or the compressor might hum without the unit actually running. Other indicators include a smell or smoke coming from the unit, the blower circulating room-temperature air instead of cold air, and an unexpected increase in your energy bills.

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.

Yes, scorpions can enter a home through AC vents, especially if the system is not well-sealed. As excellent climbers, they can scale a home's exterior and squeeze through gaps as small as 1/16 of an inch. Scorpions are often attracted to the moisture around air conditioning ducts or seek cooler areas during hot weather, using vents as a pathway inside. They may slip through small openings where the duct meets the vent cover and travel within walls before emerging. To prevent this, inspect your vents, seal any gaps, and consider installing fine mesh screens.
