An exceptional air conditioner is only as effective as the duct network feeding it. Drawing on a family trade legacy dating back to 1949, we customize and configure sheet metal components in-house. This guarantees your central system distributes air evenly, effectively eliminating hot second-floor bedrooms and balancing performance across all living zones.

Choosing the right cooling system can bring up a lot of questions. To help you navigate your home comfort options, Greg, Grant, and the Twintech team have put together straightforward answers to the most common questions homeowners ask us about air conditioning installation.
Proper A/C sizing is determined by a manual load calculation, not a generic rule of thumb based on square footage. We evaluate your home’s insulation levels, window direction, and structural age. Installing an oversized system causes it to cycle on and off rapidly (short-cycling), which leaves your home humid and wears down the compressor prematurely.
Absolutely. Older air conditioning systems operate at much lower SEER ratings, degrading significantly over a decade of use. Upgrading to a modern energy-efficient model from brands like Amana or Goodman can slash your cooling-related electricity expenses by 20% to 40% while delivering far more stable temperature distribution.
No, it will not. Your air conditioner operates on an independent cooling loop, though it does utilize your furnace’s blower motor to circulate chilled air through the house. Our licensed specialists ensure that the new indoor evaporator coil matches your existing furnace cabinet configuration cleanly without altering any baseline heating warranties.
A standard residential changeout safely takes between 4 to 8 hours to complete. This timeline includes recovering old eco-refrigerants responsibly, setting the new outdoor condenser pad, modifying sheet metal connections, and performing required safety testing. Our team strives to have your cooling fully restored by dinner time.
