About Us

Residential HVAC systems typically last 12 to 18 years with proper maintenance. Air conditioners and heat pumps reach 12 to 15 years in Georgia because heavy summer runtime accelerates compressor wear, while gas furnaces often last 18 to 25 years because they operate fewer hours annually in our mild climate.

Proper sizing requires a Manual J load calculation that factors in square footage, insulation R-value, window orientation, ductwork condition, and Georgia’s climate zone. As a rough guide, homes need 20 BTUs per square foot, though oversizing causes short cycling and humidity problems that ruin comfort even when the air feels cold.

Replace your system if it’s over 12 to 15 years old, if repair costs exceed 50 percent of replacement cost, if it still runs on phased-out R-22 refrigerant, or if you’ve faced multiple breakdowns in one season. Repair makes sense for systems under 10 years old with minor faults and good efficiency.

High-efficiency heat pumps with SEER2 ratings of 16 or higher perform exceptionally well in Georgia because they handle cooling-dominant summers and mild winters efficiently. Dual fuel hybrid systems pair a heat pump with a gas furnace for the rare hard freeze, delivering the best year-round efficiency available today.

A leak in the refrigerant lines drops system pressure below operating spec, a frozen evaporator coil blocks airflow across the cooling surface, a tripped outdoor breaker stops the condenser entirely, or a worn compressor fails to pressurize refrigerant. Before calling a technician, verify thermostat settings, filter condition, and outdoor unit operation.

Yes. Evenflow Heating and Air provides emergency AC and furnace repair across Woodstock, Canton, Holly Springs, and all of Cherokee County, with after-hours emergency service available based on technician availability. Need HVAC service quickly? Evenflow Heating and Air offers fast, priority service for urgent heating and cooling problems. We make every effort to provide same-day service whenever availability allows.

HVAC replacement in Woodstock typically ranges from $7,000 to $15,000 depending on system tonnage, SEER2 efficiency rating, ductwork condition, and brand. High-efficiency variable speed systems cost more upfront but deliver significantly lower lifetime operating costs. Financing options start around $99 monthly for approved buyers.

Georgia homes face frozen evaporator coils from extended runtime, refrigerant leaks accelerated by humid coil corrosion, clogged condensate drains, humidity control failures, upstairs-downstairs temperature imbalance from undersized ductwork, and premature compressor failure caused by the long, hot, humid cooling season that runs eight months a year.

Yes. A clogged filter restricts CFM airflow across the evaporator coil, forces the blower motor to draw higher amperage, drops coil temperature below freezing, and eventually causes compressor overload from refrigerant flood-back. Replace 1-inch filters every 1 to 3 months and high-MERV media filters every 6 months.

Yes, by a wide margin. Maintenance extends equipment lifespan by 30 to 50 percent, prevents most common breakdowns, keeps manufacturer warranty coverage valid, and saves 15 to 20 percent on monthly energy bills. Two annual tune-ups cost less than a single emergency repair visit during peak summer demand.

Raise your thermostat 2 degrees, change filters monthly during heavy use, schedule a tune-up before summer hits, seal duct leaks that waste 20 to 30 percent of conditioned air, upgrade to a smart thermostat, and replace systems over 12 years old with SEER2 equipment. These steps cut summer bills 25 to 40 percent.

Nighttime freezing usually traces back to lower outdoor temperatures combined with restricted airflow or low refrigerant charge. When the coil already runs near freezing, cooler nighttime air pushes it below 32 degrees. The fix requires checking filter condition, blower performance, and refrigerant charge against manufacturer specs.
