AC Installation & Replacement in Sebastian, FL
Serving Sebastian Homeowners with Over 50 Years of Indian River County Experience
Since 1970, Colkitt Sheet Metal & Air Conditioning has been installing and replacing residential and commercial air conditioning systems across the Vero Beach area and the surrounding Indian River County communities, including Sebastian, FL. We offer free, no-obligation estimates on all new AC installations, and our team is available 24/7/365 to answer questions and schedule service.
Sebastian’s location along the Indian River and Atlantic coast means homes here face elevated humidity and salt-laden air year-round. Those conditions put real stress on aging equipment, making a properly matched new installation important for long-term comfort and efficiency.

Signs Your Sebastian AC System Is Ready for Replacement
Coastal environments accelerate wear in ways that inland Florida homes don’t face to the same degree. Salt air corrodes outdoor condenser coils and metal cabinets, and the relentless humidity load shortens the effective lifespan of equipment. In Sebastian’s coastal environment, systems often reach end-of-useful-life in 12 to 15 years rather than the 15 to 20 years typical for homes further inland.
Beyond age, watch for these indicators that replacement may be more cost-effective than continued repair:
- Rising energy bills without changes in usage habits
- Frequent repair calls in consecutive seasons
- Uneven room temperatures or poor humidity control
- R-22 refrigerant systems with climbing operating costs now that production and import of that refrigerant has been banned
AC System Types We Install in Sebastian
Not every Sebastian home has the same layout, ductwork, or budget. We install central air conditioners, heat pumps, and ductless mini-split systems to match each property’s needs.
Heat Pumps
Heat pumps handle both cooling and heating in a single system, and they’re the most common solution for Treasure Coast homes where winters are mild and summers are long. They perform efficiently across the temperature range Sebastian homeowners actually experience.
Ductless Mini-Splits
Mini-splits are a strong fit for homes without existing ductwork, as well as additions, converted garages, and other spaces where extending ductwork isn’t practical. They deliver precise zone control without major structural work.
Central Air Conditioners
Central systems remain the standard choice for homes with existing ductwork. Proper system sizing through a load calculation is essential here. An undersized unit can’t keep pace during Sebastian’s peak summer heat, while an oversized unit short-cycles and fails to control indoor humidity. Because we handle ductwork in-house through our sheet metal fabrication capability, we can address duct condition and custom configurations as part of the same project.
Our AC Installation Process for Sebastian Homes
Every installation starts with an assessment of the home’s cooling needs. We factor in square footage, insulation, window exposure, and the humidity loads common in coastal Indian River County before recommending a system. From there, we coordinate electrical capacity, ductwork condition, and applicable building code requirements, including permitting through the Indian River County Building Division.
On installation day, our factory-trained technicians handle the full scope: equipment placement, refrigerant line connection, duct sealing where needed, and electrical tie-in. After installation, we test and calibrate the system and remove the old equipment. Proper duct design and sealing carry extra importance in coastal climates, where leaky ductwork directly undermines efficiency and humidity control.
Why Sebastian Homeowners Choose Colkitt Sheet Metal & Air Conditioning
We’re a family-owned and operated business that has been part of the Indian River County community since 1970. That history means we know the coastal climate conditions, the building styles common in Sebastian, and what it takes for a system to operate reliably in this environment year after year.
Every technician is factory-trained and certified by the manufacturers whose equipment we install. We work with Trane, Lennox, Rheem, Amana, and Carrier, giving us access to current equipment, energy-efficient options, and durable systems from trusted manufacturers. When something comes up after your installation, our team is reachable by phone, text, chat, email, or online contact form 24/7/365.
Energy Efficiency for Year-Round Cooling in Sebastian
Sebastian’s climate means air conditioning runs most of the year, and selecting a high-efficiency system at installation time can reduce utility costs over time. SEER ratings measure how much cooling a unit delivers per unit of electricity consumed over a full cooling season. Higher-rated systems use less power for the same output, which can support lower energy use through a long Treasure Coast cooling season.
We pair high-efficiency AC units with smart thermostat integration so you can manage temperature scheduling and remote control from anywhere. This supports additional energy savings on top of the gains from a more efficient unit alone.

"Colkitt has provided very professional service and we have always been grateful."
We called late at night after we found a leak coming from our new AC. A technician was sent free of charge. Steven Adcock found the obstruction outside right away and fixed the shut off valve. In addition, Brandy is always pleasant and helpful in scheduling and answering any questions I may have about service or maintenance. Colkitt has provided very professional service and we have always been grateful.- Jennifer K -
"I highly recommend this company. They are fantastic!"
I have had consistently great service with different technicians. Everyone has been professional and prompt. The last two times I had an issue with my a/c (not installed by Colkitt), I had a technician here within 2 hours one time and within 25 minutes the next time. Jerome, Charlton and most recently Steven have been fantastic. Steven ran extensive diagnostics of the system, corrected the problem (different issue than when Jerome came out) and was able to answer all of my questions. I highly recommend this company. They are fantastic!- Page W -

Colkitt has been our A/C service provider for over ten years and they have always given us great service and have been extremely responsive to our needs.- Brian Douglas -
"My only regret is I didn't do it sooner."
Two years ago I decided to replace my aging A/C with a newer more efficient unit. Colkitt provided the equipment and service I wanted in a timely professional manor. I can now say the power savings for my new unit will pay for itself in just 4 years! Amazing! My only regret is I didn't do it sooner.
UPDATE: Recently I had a need for a service call and a technician came out in 24 hours; my issue was resolved. It can't get any better.
UPDATE #2 : Once again I needed a service call and the technician came out - solved my problem in less than a hour. Very polite service tech.- Bill C -
"You are the very best!"
We own Artistic First Florist in Vero beach and have a commercial contract for service with Colkitt, they have always been great. A year ago we had a problem in our home and they came right out and had us running in 3 hours! Last night, Sunday at 3am I discovered in the middle of a hot flash that our air was out!! My husband called the office at 7am, the tech was out by 8:30 and our air was running cold by 9am! I cannot thank Colkitt enough, your service and prices are so fair, no emergency call charge! You are the very best!- Aimee D. -
"Very Professional"
We bought a new AC unit from them last year. It has been nothing but awesome since....we had a small problem and they came and fixed it right away with no charge because the service comes with the unit. Very professional, very affordable, and since we live in Florida and AC is gold here, it's nice to know you have a place you can rely on and they come in a timely fashion and take very good care of you.- Ressa K.
