Homes near the water in Roseland and along the riverfront carry accumulated salt damage into the hardest weeks of the year. That quiet corrosion turns into a complaint now: longer runtimes, a warmer house, a bill that jumped. Much of the Highlands was built out over decades on old plats, so plenty of hard-run systems are reaching end of life together.
A capacitor that tested weak in the mild months or a drain line half-clogged with algae will not survive this stretch. Both are fast fixes when we get to them, and we carry the common parts on the truck. When a system deserves a bigger conversation, we start with a diagnosis and end with numbers, never pressure.
The tech is ours, never a subcontractor, background-checked and NATE-certified, with a written price before work begins. Any replacement estimate is free and includes a full ductwork evaluation. We pull the permit, install to manufacturer spec, use copper drip pans rather than PVC, and back the work with a lifetime warranty available on qualifying systems.

How it goes
Five steps, in this order, every time. The rail beside them cools as the visit does: orange when your house is hot, ice blue when we leave.
Day or night, seven days a week. Form leads get a callback in about three minutes. We tell you honestly when we can be in Sebastian.
A NATE-certified tech finds the actual failure. Not a guess from the driveway, and not a replacement pitch.
Always a repair quote, at any system age. If replacement makes more sense, you get both numbers and you choose.
On every replacement quote. Roughly 85% of homes built for R-22 are ducted wrong for a modern system, and nobody tells homeowners that.
Copper drip pans, manufacturer spec, permit on file. That's what keeps a lifetime warranty real instead of decorative.

Never really had a good experience with AC people before but David made me feel less stressed about having to deal with an AC problem in this heat. He was very knowledgeable and super nice when explaining the issues!
★★★★★
I have been a customer of Kyzar for the past 6.5 years and have had great service. They installed my new A/C 6 yrs ago which was cost effective and energy efficient. My service today was quick and easy and Brandon is very knowledgeable about the unit. He gave me some great tips to keep my A/C in good working order between visits. Very personable and professional at all times. Kyzar came out to my place in Greenacres and performed a maintenance…

Service areas
We cover all of Sebastian: the sprawling platted streets of Sebastian Highlands, the older riverside community up in Roseland, the newer subdivisions at Park Place, Sebastian Lakes and Collier Creek, and the lagoon-side homes near Pelican Island.
Our Port St. Lucie office in Tradition is about 40 minutes down I-95, and the same crews that reach Sebastian work the towns to the south every week, including Fort Pierce and Port St. Lucie. Sebastian is the far northern edge of our coverage, but we still run trucks up here, and we will give you an honest arrival time when you call.

Questions we hear every day
Usually yes, though Sebastian is the northern edge of our map, so arrival times can run a little longer. We still run techs up here seven days a week, and a real person answers our phones around the clock, not a voicemail box like the outfits with a fake 24/7 line. Call and we will give you an honest window.
It depends on what actually failed, so we start with a diagnostic, and that fee is credited toward the repair when we do the work. You get the real price in writing before we touch anything. Estimates on new systems are always free, and they include the ductwork evaluation.
You get both quotes, every time, no matter the age. A lot of Sebastian was built from the 1970s through the 2000s, so many original systems are aging out around now. But age alone does not decide it. We diagnose first, and if a repair gets you a few more summers, that is what we will recommend.
Yes. Salt corrodes condenser coils and fins, which quietly kills efficiency well before the system fails outright. If you are near the lagoon around Park Place or Pelican Island, ask us about a coastal coil coating and a tighter maintenance interval when we are out.
Locally owned. Roughly 70% of the AC companies along this coast are now PE-owned, and Sebastian retirees ask us about it all the time. Kyzar is owned by Paolo Weston and dispatched from our Tradition office. Our techs are our own employees, background checked and drug tested, never subcontractors.
