HVAC Installation in Simpsonville and Greenville, SC

Need a New AC or Heating System?

Upstate summers are long and humid. A worn-out AC that short-cycles or struggles on 95-degree days costs you comfort and money. Cold snaps still hit hard enough that a tired furnace or heat pump leaves rooms cold overnight.

GreenTech installs central air, furnaces, and heat pumps for homes across Simpsonville, Greenville, Mauldin, Five Forks, Greer, Easley, and the rest of our service area. We start with how your home actually lives, not a one-size quote.

Commercial HVAC Installation Too

We also install commercial rooftop and package systems for Upstate businesses. One recent project: large commercial Daikin units on Amazon’s 165,000 sq ft Same-Day Delivery warehouse—crewed from our Simpsonville shop.

Repair vs. Replace: How We Decide

We repair first when it makes sense. Replacement comes up when:

• Your system is older and needs major parts often
• Repair cost is high compared with remaining life
• The unit uses outdated refrigerant that is hard to service
• Some rooms never catch up no matter how many times we tune airflow
• You want better humidity control and lower monthly energy use

Still unsure? Start with AC repair or heating repair. We will tell you honestly which path fits.

Our HVAC Installation Process

Sized for Upstate Humidity and Heat

Oversized units cool the air too fast and leave homes sticky. Undersized units never catch up on humid July afternoons. We match capacity to your home, not a sales sheet average.

Heat pumps are common across Greenville County and nearby towns. Furnaces still serve many older homes. We install what fits your house and fuel type, then explain the tradeoffs in plain English.

Brands and Equipment We Install

We work with major residential brands homeowners already know, including Trane, Carrier, Lennox, Rheem, Goodman, American Standard, Daikin, Amana, and Ruud. If you have a preferred brand, tell us when you call.
