"The owner Dave was very responsive and easy work with. Zack and Matt were extremely punctual, informative and communicative. They were able to answer any questions, no hard sale approach. We had 4 estimates, all close though we felt we received the best value from Cool Aid Air. Very neat, efficient and the product, Mitsubishi mini splits are wonderful. My wife and I deliberated as she was not a proponent of minis but absolutely loves them. Quiet and efficient.ful. he company and personnel. Highly recommend t"

"We couldnâ t be happier with the services we received from Powerhouse Air Conditioning LLC. Deanâ s response time to calls and messages were faster than any other company we have tried to contact. He came right out to our house, found the issue, then walked us through our options. He was both honest and professional. I would HIGHLY recommend Dean and his company any day!"

"A year ago they responded to an SOS related to a full A/C failure. They were prompt and professional. It took several days, in the heat of the summer, till they were able to fix it, but they had to get a part from the west coast so we sweated through the ordeal. While they were working on replacing the main board, I also engaged them to clean the system. I thought the charge was high ($1000), but needed it done. A year later, one of the A/C mini-split heads stopped working. They came the next day. I paid $200 for them to trouble shoot it, which took approximately 20 minutes. (Subsequently another A/C service charged me only $95 to trouble shoot!) They said they would order the part and get back to me. After I week, I had not heard from them. When I called they said they could get the part but it would take 4-6 weeks. I said okay. What could I say. I left it in their trustworthy hands. After 6 weeks I heard nothing from them. I called. I left 4 messages, which were all unreturned. On the 5th try, someone answered. He said he couldn't get the part. Would have been nice to know that 5 weeks ago. Still puzzled why they didn't communicate with me and thus the low review. I have to say that I thought they were really nice people, but obviously my business wasn't that important to them. So be it. But a little courtesy and honesty would go a long way when servicing a small community like Key West. Because of the later incident, I wanted to give them an F, but that wouldn't be fair. If you're lucky, have deep pockets, and the problem isn't complicated, they are okay. Just be aware. I thought I had actually found a reliable service, but that wasn't the case."

"I called Ellington Ac to see about a quote for our House in Marathon Key, I had scheduled a free quote . The Morning of the quote Mr. John Page called before hand to let me know he was on his way to the house to present a quote for a new hvac unit and ductwork, For starters he was On time and that is a good sign. He knew all the answers to any questions we had about the Trane Hvac unit. And Ductwork. He even used a thermal Camera::: How impressive:::We decided to go forward with the quote and got the middle of the road unit. The day of the installation Mr Page met the Crew at our House to introduce us to the Installing crew, they were all excellent to have in my house. Very cautious of all our belongings and also worked non stop until the job was complete. They are top notch , attention to detail was excellent ! No corners cut.

"Excellent service, very fast response to my request for service, picked up laptop, diagnosed issues. Initially thought it was an OS update issue but the hard drive had failed along with other components (including 'CPU). Because other components were involved, a new solid state hard drive was put into a laptop with a working processor - same type CPU as in the failed unit. The laptop was repaired and returned in less than a week. This company picked up and dropped off the laptop (driving from Huntsville, AL (about 60-70 minutes)-- great service in this covid environment. I would recommend this company to my family./friends and will use again."

Heating and Air Conditioning questions, answered by experts

Yes. Your air supply should be balanced. The return and supply ducts need to maintain that balance, and this only occurs because an equal amount of air should be entering and leaving your HVAC system. Changes in pressure, extreme weather, and blocking vents with furniture or your stuff can make the air supply unbalanced and cause your home to get too cold or hot.

Indications of an HVAC problem include inconsistent heating or cooling throughout your home, unpredictable temperature changes, or inadequate air flow from vents. Abnormal sounds such as grinding, banging, or hissing, and unpleasant smells like mustiness or burning are also potential warning signs. A rise in energy costs without an increase in usage may also imply decreased efficiency. An HVAC system that frequently cycles on and off or cannot maintain a stable temperature is malfunctioning.

To reset your air conditioner, start by turning it off at the thermostat. Then, shut off power to the AC system at the circuit breaker. Some units have a dedicated "reset" button; if yours does, press and hold it for three to five seconds. If your air conditioner doesn't have a reset button, or if you are resetting it after a power outage, leave the circuit breaker off for at least 30 minutes to allow the system to reset itself. Afterward, turn the power back on at the breaker, turn on the AC from the thermostat, and set it to "cool" to test the system.

The cost to install a ductless mini-split AC system ranges from $2,000 to $14,000, depending on the type of unit, the number of zones or rooms, and the complexity of the installation. On the low end, a system for one or two zones in a single room costs around $2,000. Covering two zones for more rooms can cost between $6,000 and $8,000. For a larger multi-zone system to cover an entire home, costs can be $14,000. If you don’t already have an AC system in place, you may need to add the cost of permits, an electrician, and a concrete pad.

A home AC unit provides anywhere from one-half to five tons of cooling and requires approximately two to four pounds of refrigerant per ton of cooling. At approximately five to 10 minutes to fill one pound of refrigerant, a home that requires three tons of cooling will take about six to 12 pounds of refrigerant and approximately 30 minutes to two hours to completely recharge the unit.
