"Bill and Trish exceeded the expectations I had from the start. Trish is so pleasant to talk with that you forget quickly you are asking for a service and not talking to a friend. Bill is a craftsman who has many years of experience and he gets right to the point of where your problem lies. In our case the tune up for the summer was not realistic when our 30 year old AC unit had leak issues. Bill and I worked through several scenarios regarding cost of a repair and an investment in a new unit. It made sense to do a new unit and not worry about our old AC unit further breaking down and requiring more repair. Bill and Trish advised us of a cancellation that allowed the new AC unit to be installed 3 days after the service call. Bill and Trish followed through on their quote, and arrival time for installation on time. Everything I was told with a time frame was on time,accurate, and made sense to what I was receiving. Raphael and Nisho were assigned my install and they were no different regarding their punctuality and care for our house. Bill and Raphael took me through the complete process of what would be done and when the project would be finished. Raphael and his crew treated my house well making sure to drop cloths down everywhere they worked. I could not tell they did anything because of the cleanliness in which they worked. The job was made easier as Raphael helped me to clear the work area I was supposed to clear. I was running late in clearing and Raphael helped me to clear the area without complaining or having me do it on my own which was my job. After the installation Raphael walked me through our new AC and also provided valuable recommendations on how to take care of our new unit. What I must stress is everyone from Cool Air Technologies goes above and beyond what they need to in making sure you are 150% satisfied. Raphael helped me pick quality new air filters for our AC on Amazon to make sure we knew exactly what to purchase. Bill followed up that afternoon to ensure I was satisfied and encouraged any questions I might have. The AC unit performs exceptionally. The old unit if I turned it on in the afternoon to cool the house it could only drop the temperature by a degree or 2. Our new unit brought the temperature down from 78 in the house to 74 degrees in less than an hour. We still have 30 year old ducts and vents that do not allow the best air flow so this is a great improvement. Bill installed a new AC that cost me $3,000 less than what I was quoted 2 years ago from another company. My wife and I are extremely pleased with the service provide by Bill, Trish and his crew. I love they are family owned and they have your best interest at heart when they come out and do a job for you. Please use Cool Air Technologies for your service needs. It's such a pleasure when you get to deal with honest hard working local family owned companies that take pride in their work and word they give you."

"Nathan and Gordon at Total Home Environmental are lifesavers! I was facing estimates of $10,000 to $20,000 to replace my entire AC and heating system but instead they indicated that my 25 year-old AC compressor could be resuscitated by thoroughly cleaning the terminals and adding a hard-start kit. No other HVAC technician that came out gave me this option but they pulled it off for a fraction of the price of a new install!!! They are honest and knowledgeable professionals! Thank you so much!"

"Technicians were very professional and did a great job of cleaning the dryer and 18 vents, as there has been a very noticeable change in the air flow. We had a few rooms where there was hardly any air coming from the AC but after the vent cleaning the rooms now get improved air flow and are able to cool down. Will definitely use them again."

"Oh My Gosh! What an amazing company to work with! I can’t stress enough what a pleasure it was having them in my home! John and Lauren worked smoothly and respectful throughout the day explaining everything to me. This is the first time I’ve had air conditioning. If I could give these gentlemen a 10 Star ⭐️ rating I would, period! You will not go wrong using their services from the price quote to a professional, thorough completed job! Thought it would take 2 days but no only one! Thank you John and Lauren ??"

"Bill Walker is the tech that diagnosed my faulty condensing unit compressor to be grounded. Sounds like a good thing right? but its not. You never want to hear that. Should you ever do so you want Trabuco Air handling it. I was explained what was wrong and given options that i could comfortably choose from without just breaking the the already shaking bank. Trustworthy and reliable Bill is a cool cat and confident in his skill set. He knows air conditioning extensively and will solve your needs as well. I can finally enjoy the upstairs again thanks to Bill from Trabucco Air."

"Very in detail description of what needed to get done and the why behind it. Awesome job, professional, answered every question on why my central AC was strong on first floor but very weak in second floor. Air handler moved from bottom floor to upstairs attic, higher capacity central AC and all ducts changed. Beautiful work done in 3 days with detailed report of what was done. Fair price for the job done. Before and after."

"Raymond Varela was extremely professional and timely. He explained things clearly and was able to locate and fix the clog quickly and efficiently. I could not be happier with this service. The entire system for All City Plumbing that was used was also very cool. Photos, emails, info, recommendations are all sent to my email and everyone during this interaction was great. From the first request on yelp to the final signatures."

"We had Temp Air install our AC unit. The best decision we ever made. They were fast, reliable and dependable. Excellent customer service, did a phenomenal job. After a couple of years something was going on with our unit, I called them and immediately they send out a technician Juan, who was phenomenal. He explained what the issue was and resolved it asap! Highly recommend this company!"

Air Conditioning questions, answered by experts

A one-stage air conditioner only has one setting, while a two-stage air conditioner has a high and low setting. A two-stage air conditioner costs between $500 and $2,500 more than a traditional air conditioner, but it has a longer lifespan and helps to increase energy efficiency. To make this decision, you should consider your energy needs and available budget.

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.

There are several AC unit problems to troubleshoot, but luckily you can identify them by keeping a close eye on your system. Look out for the following signs that your AC needs repair:

  • Unusual noises during operation

  • AC unit blows warm air

  • AC unit doesn’t come on or turn off with temperature changes

  • Strange odors come through the vents

  • AC unit cycles on and off rapidly

  • Indoor air is more humid or less comfortable than usual

  • AC unit keeps tripping your breaker

  • Fan in the outdoor compressor doesn’t operate when the AC is on

Florida rooms can have heat or air conditioning, although not all do. These rooms can be added to the existing HVAC system or use a mini-split system, or they may just use a ceiling fan or the breeze from the windows for cooling. Florida rooms with air conditioning often have glass windows to keep the cool inside instead of just mesh screens.

This is a bit of a trick question. Even though the seasons arrive at the same time every year, the weather doesn’t always behave according to the calendar. So, while it’s fair to say that you can expect to turn on your AC starting in late May or early June, it all depends on the outside temperature and how cool you like to keep your home.
