    HVAC Install/Repair

    "Derek has an excellent work ethic and attention to detail, that is hard to find in todayâ s environment. Derek promptly repaired my 30-year old Carrier gas furnace with a few new factory parts , and it runs like new. While there, he also performed a spring tuneup and cleaning on the outdoor condensing unit and indoor heat exchanger, tested the thermostat, and checked Freon pressure. I recommend Derek to my neighbor, and he ended up having Derek install a whole new 3-ton Carrier indoor/outdoor split system and gas furnace. My neighbor was extremely satisfied with the workmanship and price. I am extremely pleased that my neighborâ s new condensing unit is so quiet, that it no longer wakes me up at night when it runs! Overall, this is best value out there for any air conditioning/heating repair or new installation!"

    "I work in the trades, so im no easy critic. My elderly motherâ s furnace went out, and was in need of repairs. Chris and his company were my choice, and let me tell you, was I impressed. Showed up same day within a few hours, diagnosed the issue, He presented multiple options to my mother, kept me updated along the way, and got the repair done SAME DAY!!! My mother was impressed with how clean he was, how much he cleaned after, and even scheduled a follow up for 6 months later to ensure the system is functioning as intended. Will definitely be using Chris for all my HVAC needs and referring him to everyone and anyone that asks!"

You can be sure that when the time comes to change my units, I will hire them without hesitation! Thank you so much!"

    "I have an older central air system that would not turn on. Nick came out and diagnosed the problem. He got my system up and running quickly; just in time for a heat wave. The problem was bigger than I hoped, but I gained confidence I was give correct advice about what needed to be done. Nick was knowledgeable and explained everything in an understandable way. He was friendly, on time, worked efficiently and did quality work, In addition to Nick, owner Rick reached out to make sure I understood everything and was a satisfied customer. I wish to point out Nick tried a less involved and less expensive fix that did not work. He essentially donated that time without charging for it. I appreciate that they tried to solve my problem in the most economical way possible. I highly recommend this firm and will use them again."

    "True Air Mechanical is a very great company to work with. Pete our salesman was so very helpful, and patient with us. He was concerned about finding the right system and cost effectiveness for us since we are on a fixed income. He was not a pushy salesman and gave us time to do more investigation. Brian our installer was professional, perfectionist and such a pleasure to work with. He explained all aspects of the system. True Air recommended Carrier system, heat pump and ac unit."

    "Derrick came highly recommended, and I can see why! He was courteous and professional throughout the entire project. I wanted to figure out why my first floor HVAC unit was having trouble cooling (and heating too) and Derrick was able to diagnose the problem quickly, explain it simply, and fix it. He communicated with me and kept me in the loop the entire time, letting me know the timeframe of the repair, when to expect him, and so on. And as someone who works a 9-5 every day, I really appreciated the communication so I knew when to be home! Derrick and Coastal Comfort are my go-to's now for all things HVAC. Highly recommend!"

    "This HVAC company is honest and professional, definitely the one to hire. I had another company replace my A/C units last summer and level the furnace, but the system broke down after 6 months. There were several parts of the system that they failed to repair or even inform me about. Reese spent the time to give me a fair and accurate estimate, and even encouraged me to get other estimates before hiring them! Lance the installer came out to replace my old furnace and repair a few parts of the A/C system that had been slapped together, but he went above and beyond to expand my attic access, improve the drainage and bring the whole system up to code. The A/C and heating work great now, and my family and I feel safer knowing that Lance put in the extra time to carefully check everything."
