"I highly recommend Florida Air Flow Heating and Air for air conditioning repair, zoned ac system repair, and replacement services. The owner Aldi along with his team of technicians has been servicing my ac system for years and he has replaced my system and my sister's system in the past. He always does an amazing job to get someone out to fix your system as soon as possible and his pricing for repairs and replacements is always fair and honest. I recommend Aldi and Florida Air Flow Heating and Air to all of my family and friends and I will continue to do so for the foreseeable future. Thank you Aldi for saving us from the Florida heat during the summers we really appreciate it!"

"It was absolutely amazing to work with E Z air conditioning. He was on time to the appointment and was very clear about what work needed to be done and how much it would cost. When it came to pricing, he was willing to present all the details to me with such clarity that I didn’t feel like he was hiding anything. His candid way of communicating makes you feel like you’re just chatting with a normal person and not a slimy sales guy. The work took about 2 hours and it was worth every penny. Peace of mind and quality work. Thank you E Z Air!!!"

"Technicians Darius and Matt were very professional, customer-friendly, and definitely knew their trade. They identified the problem in a short time and worked diligently to find a replacement part, get it installed, and the system back on line. It’s cool to have cool air again. Thank you to Maurice and crew. Job well done"

Heating and Air Conditioning FAQs, answered by experts

Whether an HVAC damper should be open or closed depends on the season, the zone it controls, and the temperature in that zone. In the summer, open upstairs dampers and close lower-level dampers to get the most efficient cooling possible. In the winter, do the opposite. Cool air will naturally flow down to lower levels, while warm air will rise. This keeps your system from working harder and helps prevent common AC problems.

There are many signs of a bad AC fan motor, including if the fan blades don’t spin when the AC kicks on or if they keep spinning when the AC is off. The AC fan cools down the condenser coil, so a faulty motor can also cause the system to overheat. Unusual noises in the exterior AC unit, including grinding or rattling sounds, may also be a sign that the AC fan motor is worn out.

Setting your AC unit to 78 degrees can, indeed, help you save energy. In fact, according to experts, every degree you turn the unit up could save you between 1% and 3% on your energy bills. That said, turning your unit off entirely while you’re out might actually be less efficient than keeping it on at a higher temperature. Why? The unit will need to work extra hard to cool the house back off again after all those hot hours. 

Yes, it is possible. An electrical fire can break out if the compressor has inadequate ventilation. When it overheats but doesn't have a proper thermal cutout, this can cause the motor to short-circuit and catch fire. This risk is exacerbated if flammable materials, like dust and fallen leaves, are clogging the unit. The compressor overheating won't start a fire by itself, but poor maintenance and installation can increase the risk once it hits its breaking point and short-circuits.

A new air conditioner capacitor will cost less than replacing the entire air conditioner system. While a capacitor itself will cost between $8 and $25, paying a professional to replace an AC capacitor will cost $180 on average. It’s not safe to replace an air conditioner capacitor on your own.
