"I had an excellent experience with Coastal Air and Plumbing and couldn’t be happier with the plumbing installation. From start to finish, the crew was professional, knowledgeable, and took pride in doing the job right. A special thanks to Vihn, John, Addonis, and Mihn. They were great to work with, answered our questions, kept us informed throughout the installation, and made sure everything was completed properly. I especially appreciated their attention to detail and willingness to explain what they were doing along the way. It’s refreshing to work with a crew that is dependable, respectful, and clearly cares about the quality of their work. I would absolutely recommend Coastal Air and Plumbing to anyone looking for professional plumbing services. Five stars all around!"

"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."

Heating and Air Conditioning FAQs, answered by experts

It is possible to add air conditioning to an older home, but it can be very expensive to do so. Expect to pay anywhere from $6,000 to $17,000 or more for the ductwork and AC unit. You’ll also have to hack into the home’s walls and ceilings to add ductwork, which can impact the aesthetics of an old home.

You need to know the square footage of your home first. Multiply that number by 20, which will get you the BTUs (British Thermal Units) needed to cool your home efficiently. Homes up to 1,000 square feet usually need a 1.5-ton unit; homes 1,000 to 1,200 square feet usually need a 1.75-ton unit, and homes 1,200 to 1,400 square feet usually need a 1.9-ton unit. Talk to a local pro for more specific advice on your home. 

Most units are designed only to cool the house down to 20 degrees less than the temperature outside. This means that if it’s 99 degrees Fahrenheit out and you’re trying to cool your home down to 65 degrees, you’ll notice your AC is struggling. 

Lower the blinds on all your windows, turn on your ceiling fans, and keep the thermostat at a consistent temperature to help your AC do its job. Investing in an HVAC maintenance plan also helps because pros will come out to inspect and tune up your unit regularly, keeping it in optimal working condition.

It’s never a good idea to run your AC without a filter, even just for a night. The filter defends your HVAC system from the dust, dirt, debris, and other grime in your home. Without a filter, those contaminants are more likely to get inside your system and potentially damage it. 

A 3-ton AC unit is probably too big for a home that’s 1,200 square feet. If you have a 1,200-square-foot home, you likely need a unit that’s somewhere around 1.9 and 2 tons. An AC unit that’s too large will be really inefficient and cost you a lot of extra money on your bills.
