Most AC calls start with one of these. A technician tests the system to find the cause before recommending a repair.
Warm air from the vents can come from a failed capacitor, low refrigerant, a dirty coil or an outdoor unit that isn’t running. Why your AC isn’t cooling.
Weak airflow
A clogged filter, a struggling blower motor, a frozen coil or leaky ductwork can leave rooms with barely any air. Duct cleaning & sealing.
Frozen coil or water leaking
Ice on the lines or water around the indoor unit usually points to an airflow problem, low refrigerant or a clogged drain line. What an iced-up coil means.
AC won’t turn on
Thermostat, wiring, contactor and safety-switch problems can all keep the system from starting.
Short cycling
A system that turns on and off every few minutes can have an electrical fault or be oversized for the home.
Strange noises or smells
Grinding, buzzing, squealing or a burning smell is a reason to shut the system off and call.

Heating Repair
When the heat goes out, we diagnose gas furnaces, electric furnaces and heat pumps by measurement, not guesswork.
A furnace that runs without heating, or won’t start at all, often has an igniter, flame sensor, pressure switch or control board problem.
Heat pumps can lose heating capacity from low refrigerant, a stuck reversing valve or a defrost problem.
Furnace short cycling
Frequent on-off cycles can mean overheating, a dirty flame sensor or a restricted filter. Why furnaces short cycle.

The Whole Home Matters
Your heating and cooling system doesn’t work in isolation. Ductwork, controls, insulation and air leakage all affect how well it heats and cools your home. A new or repaired system works best when the rest of the house is working with it.
Home Comfort
These parts work together.
Heating & coolingHeats and cools the air in your home.
DuctworkCarries conditioned air to every room.ThermostatTells the system when to run and when to stop.
InsulationSlows heat moving through attics, walls and floors.
Air sealingStops air leaking through gaps and cracks.Right-Sized for Your Home
An oversized AC short-cycles, won't dehumidify and burns out compressors years early. An undersized one runs nonstop and never catches up. Either way, you pay for it on your power bill and in repairs.
Before we quote a replacement system, we perform a Manual J residential load calculation — the ACCA industry-standard sizing method that accounts for your home's insulation, windows, orientation, duct losses, infiltration and Georgia's actual climate data. Not a square-footage rule of thumb. Not a "your old system was a 3-ton, so the new one is a 3-ton" shortcut. The real math.
It takes us longer up front. It saves you money for years to come. That's the Anderson Difference on every install.
How We Work
Our NATE-certified technicians test capacitors, contactors, control boards and refrigerant pressures before recommending a repair. We replace what's actually broken — and tell you what's likely to fail next so you can plan.
Installation Process
The same process applies whether you’re replacing an AC, a furnace, a heat pump or the whole system.
Measure the home
A Manual J load calculation, plus blower-door and duct testing, shows what size system the home actually needs.
Choose the equipment
We match the indoor and outdoor equipment to the load and give you a firm price, with financing and rebate options where they apply.
Install
Our own crews remove the old equipment and set the new system. Most replacements are a one-day job.
Commission and verify
A deep vacuum, refrigerant charged to spec by measurement, and airflow checked before we call it done.
HVAC Installation
When replacement is the better choice, we size the new system to your home and install it with our own crews.
Right-sized central air from a Manual J load calculation.
Furnace replacement
Gas and electric furnaces sized to the home, often paired with a new AC or coil so the system is matched.
Central heat pumps and ductless mini-splits for whole homes or single rooms.
When ducts need changing, our sheet metal shop at 519 Pine Street fabricates them to fit. Ways to pay: financing through approved lending partners and Georgia energy rebates where they apply.

FAQ
Every repair starts with our flat $89 diagnostic, waived when you choose a repair or install option. Once we pinpoint the issue, you get a firm, upfront price before any work begins — no surprises.
Common causes include a failed capacitor, low refrigerant from a leak, a dirty coil or filter, a frozen evaporator coil or an outdoor unit that isn't running. A technician needs to test the system to know which one it is.
Repair usually makes sense when the failed part is a smaller repair and the system has been reliable. Replacement is worth comparing when a major part like a compressor, coil or heat exchanger fails on an older system, repairs keep coming back or the system uses R-22. We'll give you a price for both so you can decide.
Most replacements are a one-day job. Before that day, we run the load calculation, test the home and ductwork, and give you a firm price, so the install itself goes smoothly.

Every Anderson replacement install starts with a Manual J residential load calculation — the ACCA industry-standard sizing method.
