"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

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.

In most cases, you should hire a professional to carry out services on your HVAC system, as the components are complicated, expensive, and potentially dangerous to work with. However, there are a few things you can do on your own to keep your HVAC system in good condition, including changing your filters every three months, keeping the area around your outdoor condenser clear of debris and plant growth, making sure your or intakes aren’t blocked, and keeping an eye out for increased energy bills, strange noises, and unusual odors related to your equipment.

Here’s how AC professionals will clean your AC coils:

  1. Unplug the AC unit or turn off the breaker to the unit in your circuit breaker box.

  2. Remove the faceplate.

  3. Spray a vacuum hose attachment or compressed air can to remove debris, dust, dirt, and grime.

  4. Use a soft-bristled fin comb to remove stubborn caked-on debris.

  5. Use the vacuum hose to suck up any extra debris.

  6. Take a coil-safe cleaning solution and spray it onto the coils. Try to choose a no-rinse solution.

  7. Let the solution sit for at least 15 minutes.

  8. Gently wipe away loosened grime and debris with a microfiber cloth.

  9. Reattach the faceplate, plug in your AC system, or turn the breaker back on.

The cost to replace an AC unit averages around $5,900, with a typical range between $3,900 and $8,020. The final price depends on several factors, including the type and size of the air conditioner, its efficiency rating, your geographic region, and labor costs for installation. Smaller units like portable and window ACs are much less expensive, costing between $90 and $550, compared to central or ductless systems. If your current unit is less than 10 years old, repairing it may be more cost-effective than a full replacement.

When an evaporator coil becomes faulty, it can result in various problems within your HVAC system. These problems could include reduced cooling or heating capabilities due to ice formation and obstructed airflow, along with increased energy consumption and higher bills. Additionally, a damaged coil may lead to refrigerant leaks, which are environmentally harmful and decrease overall system efficiency.

Ultimately, if not addressed right away, a bad evaporator coil can even lead to a complete failure of your HVAC system. That’s why timely repair or replacement is crucial to maintaining your family’s comfort and your HVAC’s efficiency.
