"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

Swamp coolers cost approximately 50 percent less to install than central air conditioners and cost less to run. Operation costs depend on the size of the unit and home, your climate, utility rates in your area, and the system’s efficiency. Swamp coolers use 15 to 35 percent less power than air conditioners.

No, for two very important reasons. First, it’s illegal to release refrigerant into the air or ground since it can be toxic and cause environmental damage. Technicians typically pump old or extra refrigerant into separate tanks for special disposal. Second, without professional equipment to read refrigerant pressure and levels, plus the AC’s suggested requirements, it’s impossible to know if you’ve removed the right amount of refrigerant. Stay away from a DIY solution here and seek an expert with the right tools.

The average life span of an HVAC system is 15 to 20 years. Even if your old air conditioner is still functional, it isn't as energy-efficient as a newer system (especially one with an Energy Star designation). Older HVAC systems aren't as efficient, and the 10-year mark is when you should start making full system replacement plans. Twenty years in, that plan should be well underway rather than waiting for the unit to die.

When your HVAC system is loud, a few different causes are possible. If you have loose connections or bolts in the hardware, they can rattle as the system runs and vibrates. If you have an extremely dirty furnace filter, it could cause the system to generate noise. More commonly, an excessively loud HVAC system indicates a malfunction in the system. You may have a blower motor that is close to failing or a compressor that is breaking down. These issues require an immediate inspection.

A common HVAC rule is that for every 500 to 600 square feet of living space, you need 1 ton of heating or cooling capacity. Now that you know this common rule, you also need to know that it isn’t very accurate, and a dedicated pro wouldn’t use it for your home. If you talk to a pro who won’t or can’t perform a proper Manual J calculation, consider hiring someone more thorough.
