Stuart is the Martin County seat, built around the water where the St. Lucie River meets the Indian River Lagoon, and that shapes the work. We handle salt-air condenser rebuilds on the riverfront and near-coastal homes at Rocky Point, Krueger Creek and Poppleton Creek, replacements on the aging systems in the established neighborhoods off downtown and out at Cedar Pointe, and repairs and tune-ups in the golf community at The Florida Club. We work condensers, heat pumps, air handlers, every major brand. In a town this size, one of our 47 trucks has already worked your street.
Stuart is affluent with a heavy snowbird presence, and both make it an easy town for a contractor to oversell, which is exactly why we do the opposite. About 70% of the cooling work in this region now runs through private-equity-owned companies, and their answer to a hot house is almost always a new system. We diagnose first, every time. You get a repair quote at any system age, even when the honest call is that a $400 capacitor beats a needless replacement. If a seasonal home sat empty and came back warm, or you are holding someone else's quote, get our second opinion before you spend.
A background-checked, NATE-certified tech shows up in a uniform and booties, in a branded truck, never a subcontractor. He diagnoses the actual failure before anybody talks price, and the price goes in writing before he touches a thing. If it turns into a replacement, the free estimate includes a full ductwork evaluation, because roughly 85% of homes built for the old R-22 systems are ducted wrong for a modern one. We pull the permit, we install to manufacturer spec, we use copper drip pans, and the whole thing is backed by 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 Stuart.
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…

Questions we hear every day
Same day in most cases, and we mean it. Our Tradition office is about 20 minutes north, we run techs through Stuart seven days a week, and a real person answers our phones 24/7. Unlike the companies whose round-the-clock line quietly rolls to voicemail, we take new customers on nights and weekends. Call and we will tell you honestly when we can be there.
It depends on what is actually broken, so we start with a diagnostic, and that diagnostic 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. Much of Stuart went up between the 1970s and the 1990s, so a lot of original systems are aging out together right now, and river salt has often aged them faster still. But age alone does not decide it. We diagnose first, and if a repair buys you a few more summers, that is what we will recommend.
Absolutely, and it is one of the smartest calls a seasonal Stuart owner can make. A house that sits closed through the summer humidity can come back to a moldy, struggling system, so we will inspect it, clear the drain, check the charge and catch small problems before they become an emergency on your first hot night back.
Yes. Homes at Rocky Point, Krueger Creek and Poppleton Creek sit on brackish water, and that salt corrodes condenser coils and contacts, quietly killing efficiency well before the unit fails. If you are on or near the water, ask us about a coastal coil coating and a tighter maintenance interval when we are out.
Locally owned, and it is a fair question, because roughly 70% of the AC companies in this region are now PE-owned. Kyzar is owned by Paolo Weston and dispatched out of our Tradition office up the road. Our techs are our own employees, background checked and drug tested, never subcontractors.
Still have a question? Call us at (561) 640-1000.
Same-day service, honest diagnostics, and a real person on the phone 24/7. Your comfort is one call away.
