what makes QUAL-TECH different?
Our technicians are not salesmen. They fix air conditioning systems and provide an unbiased assessment of your system's condition.
Our philosophy is based on treating customers the way you want to be treated. Your comfort and budget are our top priorities.

When your technicians are focused on quality work, you take the time to do the job right. Everyone's happy.

If your unit is over 10–15 years old and needs frequent or costly repairs, replacement may be the better option.
While many AC issues can be fixed, at a certain point, replacement is more cost-effective than ongoing repair. Key factors to consider include the age of your unit, its energy efficiency, repair history, and the cost of current repairs compared to the price of a new system. Modern AC units are more efficient and can lower utility bills significantly. If you’re constantly calling for service or the system uses outdated refrigerant, upgrading can be a smart move.

The right AC size depends on your home’s square footage, insulation, and climate.
An HVAC technician calculates size using a Manual J load calculation. This considers square footage, insulation quality, number of windows, and local climate. An oversized unit wastes energy, while an undersized one struggles to cool. Proper sizing ensures comfort and efficiency.
For more on this topic, see our blog Do You Have An Undersized AC Unit.
Central AC uses ducts; ductless mini-splits cool specific rooms without ductwork.
Central AC delivers cool air through ducts, ideal for whole-home cooling. Ductless mini-splits use indoor wall-mounted units for targeted cooling, great for additions or homes without ducts. Mini-splits are often more efficient in small areas, while central AC offers even cooling across multiple rooms.
Most AC installations take one to three days, depending on complexity.
A straightforward replacement may be completed in a single day. However, if ductwork repairs, electrical upgrades, or new lines are required, installation can stretch to two or three days. The timeline depends on the home’s condition, system type, and any additional upgrades.
