View OptionsIndoor Air Quality and Ductwork Services
Comfort is about more than temperature. The air moving through your vents affects how your home feels, smells, and how well your family breathes. Our indoor air quality services include:
- Duct Cleaning: Removes built-up dust, pollen, pet dander, and debris that your system keeps recirculating through every room
- Duct Sealing: Closes leaks in attic and crawl space ductwork so the air you pay to heat and cool reaches your living space
- Air Cleaners & Filtration: Whole-home air purifiers, UV light systems, and upgraded media filters that trap allergens and airborne contaminants
- Humidifiers & Dehumidifiers: Pull excess moisture out during humid Georgia summers and add it back when winter heat dries out the air
- Smart Thermostats: Programmable, app-controlled thermostats that learn your schedule and help trim energy costs
Urgent HVAC Repair in Loganville
A dead AC in the middle of a Georgia heat wave or a furnace that quits on a freezing night needs attention fast. Our phones are answered day or night, so you can always get through. We work hard to offer same-day service and will get a technician to your Loganville home as quickly as possible.
While you wait, check that your thermostat is set correctly and your breaker hasn’t tripped. If you ever smell gas or your carbon monoxide alarm goes off, leave the house right away and contact your gas company or emergency services from outside.
Call (770)-273-9090Signs Your HVAC System Needs Service
Most HVAC trouble builds slowly before a full breakdown. Give us a call if you notice any of these:
- Warm Air on a Hot Day: The AC runs, but the vents blow lukewarm air or the house never reaches the temperature on the thermostat
- Short Cycling: Your system kicks on and off every few minutes instead of running full cycles
- A Sticky, Clammy House: Indoor air feels damp even when it’s cool, a sign your system isn’t pulling enough humidity out
- Ice or Water Where It Shouldn’t Be: Frost on the refrigerant line or water pooling around the indoor unit
- New Noises or Smells: Grinding, squealing, or banging from the unit, or a burning smell that lingers after startup
- Climbing Energy Bills: Higher bills with no change in how you use your system usually mean it’s working harder than it should
Catching these early usually means a smaller repair and fewer surprises.
Why You Should Hire a Licensed HVAC Contractor in Loganville
Georgia requires HVAC contractors to hold a state conditioned air license, and that license protects you. Here’s what you get when you hire a licensed pro instead of a handyman or an unlicensed installer:
- State-Verified Qualifications: Licensed conditioned air contractors have met Georgia’s experience and testing requirements
- Safe Refrigerant Handling: Federal law requires EPA certification to work with refrigerants, which protects your system and the environment
- Gas and Electrical Safety: Furnaces and heat pumps involve gas lines and high-voltage wiring that need to be connected and tested correctly
- Code-Compliant Installation: New equipment goes in to meet local building codes, with permits pulled when the job requires them
- Protected Warranties: Many manufacturers require professional installation and registration to honor equipment warranties
- Insurance Coverage: If something goes wrong during the job, you’re not the one left holding the bill
Keep Smiling holds Georgia Conditioned Air License CN210975, and every technician is background-checked and drug-screened before stepping into your home.

Common HVAC Problems We Fix in Loganville
Loganville’s weather is hard on heating and cooling equipment. Summers bring months of heat and heavy humidity, spring coats everything in yellow pine pollen, and winter cold snaps can push heat pumps past their comfort zone. Here’s what that tends to look like in local homes:
- Clogged Condensate Drains: Your AC pulls a lot of water out of humid Georgia air, and algae buildup in the drain line can cause leaks and system shutoffs
- Dirty Coils and Filters: Spring pollen and summer dust clog outdoor coils and indoor filters, cutting airflow and efficiency
- Failed Capacitors: Long stretches of high heat wear out the parts that start your compressor and fan motors
- Storm and Surge Damage: Summer thunderstorms and power flickers can damage control boards and other electrical components
- Frozen Evaporator Coils: Restricted airflow or low refrigerant can ice over the coil and stop cooling completely
- Heat Pumps Struggling in Cold Snaps: When temperatures dip below freezing, worn or undersized heat pumps lean hard on expensive backup heat
If any of these sound familiar, our team handles AC repair and heating repair throughout Loganville.
HVAC Costs and Financing in Loganville
Every HVAC job is priced on what your home needs. A simple repair might be a quick part replacement, while the cost of a new system depends on several factors:
- System size and the square footage it has to heat or cool
- Equipment type, such as a heat pump, furnace, or dual-fuel setup
- Efficiency ratings and features like variable-speed operation
- Condition of your existing ductwork, wiring, and drain lines
- Installation access in attics, crawl spaces, or closets
- Warranty length on parts, labor, and equipment
Your technician gives you a clear price before any work begins. If your system is 10 years or older and facing an expensive repair, we’ll price out both repair and replacement so you can compare. When a new system makes more sense, we handle air conditioning installation and heating installation and replacement from start to finish. For larger projects, we offer financing through Service Finance and Chowder, and our team will walk you through your options in person to find a monthly payment that fits.
