“Very communicative with updates and replies. I needed a whole new central AC unit. They came by to scope it out, provided a reasonable estimate, and installed it within a week. Whole crew was super nice and courteous. Highly recommended.”

How It Works

A Simple & Stress-Free Process

We know having work done in your home can feel overwhelming. Here's how we make it as smooth as possible.

    Your estimate is good for 30 days. When you're ready, approve it through the link in your email and we'll reach out to schedule.

  6. 6

Who Shows Up

The Kintech Standard

Your home is more than a jobsite to us.

  • 600PSI Pressure Test

    Every refrigerant line is tested with nitrogen and held, so a leak never makes it past installation day.

  • Full Vacuum Before Any Refrigerant

    Moisture and contaminants pulled out first. Skipping this is a leading cause of early compressor failure.

  • R-454B or R-32 Refrigerant, Included

    The latest generation, lower-impact refrigerants, with the full charge included in every installation.

  • Emergency Drain Pan and Float Switch

    A pan under the system catches any overflow, and the switch shuts it down before water can do damage.

  • Respect For Your Home

    We're courteous of your home and make sure we leave it the same as when we got there.

Frequently Asked Questions

How long does an AC installation take?+

Most replacements are completed within a single day. We tell you the timeline before the work starts and keep you updated if anything changes.

What happens during the free on-site estimate?+

We visit your home, look at your current system and layout, and put together a custom estimate with clear options and honest pricing. It's free, there's no obligation, and the estimate is good for 30 days.

What's included in a Kintech AC installation?+

More than the equipment. Along with the 600PSI pressure test, the full vacuum and the refrigerant charge, every ducted installation includes custom ductwork fabricated on site, insulated refrigerant lines, a PVC pad under the outdoor condenser, dual drain lines, airflow dampers on new supply ducts, a filtered return grill, an R11 flush of any existing refrigerant piping on replacements, a programmable thermostat, and a complimentary air balance once the system is running.

Will you remove my old system?+

Yes. We handle everything, including the safe removal and proper disposal of your old air conditioning equipment and its refrigerant.

Do you offer warranties on new installations?+

Yes. Every installation includes a 1-year Kintech labor warranty: if something goes wrong with the installation, we make it right. On top of that, the manufacturer's warranty covers parts and equipment for 5 to 10 years, depending on the system.

Do you offer financing?+

Yes, through Synchrony. On a replacement, 0% interest if the balance is paid in full within 18 months — and if it isn't, interest is charged from the purchase date, so the plan only pays off if you clear it in time. You can prequalify in seconds with no impact to your credit score, and apply in minutes during your estimate visit. Our financing page walks through every plan and what happens at the deadline. Subject to credit approval; minimum monthly payments required.

Will I need a new thermostat?+

Every installation comes with a basic programmable thermostat, with the option to upgrade to a WiFi smart thermostat. We set it up and show you how it works before we leave.

What are the benefits of a high-efficiency cooling system?+

High-efficiency systems use less energy to provide the same amount of cooling, lowering your energy bills and reducing your carbon footprint. How much you save depends on the age and condition of the system it replaces, which is part of what the estimate visit looks at.
