Union City sits in south Fulton County along I-85, where GA 138 meets the interstate and US 29 runs through town toward Fairburn. I'm Hank. My crew at Mars Appliance Repair repairs refrigerators, freezers, ice makers, wine coolers, ovens and ranges in Union City homes, and we offer same- or next-day visits.
When something quits, call (470) 516-8711; a person answers 24/7. Or send the form on this page, and we'll get back to you to agree on a time.

Tell Hank's crew what's acting up and the best number to reach you. We'll call you right back to lock in a Same- or Next-Day slot — no obligation, no upsell circus.

new and older fridges that won't hold a steady temperature.
freezers with iced fans, blocked vents or soft food.
ice makers that won't start or keep making tiny cubes.
wine coolers whose displays go dark or whose cabinets warm up.
ovens that heat unevenly, smoke or never preheat.
ranges with loose knobs, stiff valves or weak burners.
Someone slid a can of soda into the freezer to chill it fast, then forgot about it. Water grows as it freezes, so cans split and glass bottles crack. Now there's sticky brown slush frozen to the shelf, the walls and maybe the back of the freezer.
How to clean it up without making things worse:
When to call us:
One habit saves the mess: set a phone timer for twenty minutes whenever a drink goes into the freezer.
A brand-new refrigerator is the last thing anybody expects to need a tech. But a few steps on delivery day decide how it behaves for the first weeks.
If the new fridge has an ice maker or a dispenser, take a look behind it about an hour after the water is turned on. Run a dry paper towel around the fitting at the back and along the supply line. A slow drip there can soak a floor for weeks before anyone notices. If the towel comes back damp, shut the supply valve and have the fitting redone. Keep the old fridge or a cooler running until the new one is cold, so nothing spoils while you wait.
Give it a full day. If it's still warm after that, it hums but never cools, there's water at the back, or a door won't stay shut, book a visit. Brand-new parts can fail too, and a quick test tells you whether it's an install problem or a defect.
Here's a small one that puzzles people with a new range or a new home. Most gas range knobs have to be pushed in before they'll turn. It's a safety design: a bump from a hip or a pot handle shouldn't be able to open the gas. If a knob seems frozen in place, press it in first and then turn it toward light.
A different problem is a knob that spins round and round without moving the burner. Inside the knob is a plastic insert that grips the valve stem. When it cracks or wears smooth, the knob slips. What to do:
If the knob is fine but the stem itself feels gritty, very stiff or wobbly, or you smell gas near a knob, stop using that burner, turn it off and call. Gas valves are work for a tech.
You call: by phone or the form, day or night. A person picks up 24/7 and books a same- or next-day visit.
We check: the tech looks at power, water, gas and settings first, then tests the parts connected to your symptom and shows you what failed.
We repair: with your go-ahead, the tech puts in genuine or OEM-approved parts and runs the appliance before heading out. The work is covered by up to 6 months of warranty on parts and labor.

My techs repair Whirlpool, GE, Samsung, LG, Frigidaire, Maytag, Kenmore, Amana, Hotpoint, Hisense, Haier and Electrolux in Union City homes, along with wine coolers from many makers. Years of work on these brands stand behind every visit.

Same- or next-day visits are available in Union City. A morning call gives you the widest choice of times.
Please don't. Soften it with a warm, damp cloth instead; sharp tools can puncture the cooling tubes.
Liquid may have frozen around the fan or blocked a vent. If it hasn't recovered in a day, book a visit.
Several hours for most models, and it may take a full day to settle. Load it gradually.
The first batches often do. Toss them and give the ice maker a day or two.
Try pushing it in first. If it spins without moving the burner, the knob insert is worn and the knob needs replacing.
Up to 6 months, for the part and for our labor.
