"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."

"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.

"We recently had work done by Iron Air. A service issue with no heat during cold weather became a new a/c install due to age and availability of parts. Joe got us information and pricing quickly and scheduled the work. The work was completed in a professional, competent and efficient manner. The technicians were patient with all our questions and were careful inside and out and left all areas clean. All follow-up communication was excellent and timely. The value of the product and installation was excellent. The company went out of their way to give above average service. We highly recommend Iron Air."

"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

Not if you have a standard unit. Because portable AC units actually work to dehumidify the room, you’ll likely need to drain the unit from time to time—but you won’t have to put water into it. There is, however, another type of air conditioner called a swamp cooler that requires water to operate. If you have a swamp cooler, you may need to fill a reservoir with water and potentially ice. But a swamp cooler is different from a standard portable AC unit.

You can buy a house with a 15-year-old HVAC system if you inspect the system for performance and budget for a replacement within the next three years. You can also negotiate the price with the sellers. Ask to look at the unit’s maintenance records and energy bills for the last two years to determine the shape of the HVAC system and its operating costs. Spend time in each room of the house to gauge if the HVAC keeps the home at a consistent temperature throughout.

When faced with HVAC issues, it's best to begin by ensuring the thermostat settings are correct for either heating or cooling. If the system isn't responding, check the thermostat for proper function and power supply. It's also important to examine air filters, as clogged ones can decrease performance. Confirm the power supply to the system by checking the circuit breakers and fuses. If these basic steps fail to resolve the issue, contact an HVAC professional for a more detailed diagnosis and repair.

Choosing a unit with higher BTUs can use more electricity if the BTUs are more than what’s necessary for your room size. However, choosing an AC with BTUs that match the size of your room or house, your unit will cool your space efficiently. On the flip side, choosing a system with not enough BTUs can cause the system to work harder to try to cool the space, leading to more electricity consumption and higher energy bills.

There are a few ways to determine if a vent is open or closed. You can inspect the vent and examine the position of the fins. If there are spaces between them, the vent is open. If the fins are flat and touching, the vent is closed. You can also stand under the vent when the system is running to see if you feel air flowing through it.
