Styles & brands we work with




Evaporator Coil Cleaning in Union City
Evaporator coil cleaning in Union City costs $150 – $300 as a standalone service, or it’s included in a full HVAC Cleaning package. The evaporator coil sits inside your air handler, and in Union City’s humidity it becomes a magnet for biofilm, mold, and dust. When that coil gets caked, your system runs longer to hit the same temperature, and your power bill climbs. We’ve pulled coils out of homes in the Fairways at Shannon that looked like gray carpet, not metal. You can’t fix that with a filter change.
Why High-Efficiency Systems Need It More
Union City homes from the 2000s boom were built with high-efficiency HVAC systems designed to run nearly year-round. That constant runtime means more air passing over the coil, more moisture, and more microbial growth. Skipping evaporator coil cleaning on these systems is like changing your car’s oil but never the filter. The coil re-contaminates the ducts within weeks, undoing every other cleaning step.
What You’ll See When We’re Done
We use negative-pressure extraction, meaning loosened debris goes straight into the Nikro HEPA vacuum, not back into your living room. After cleaning, we photograph the coil so you can see the difference. A properly cleaned coil should look close to bare metal again. If it doesn’t, we’re not done, and you’re not paying extra for us to finish the job right.
AC Duct Cleaning in Union City
AC duct cleaning in Union City runs $300 – $500 for a standard single-system home, which covers all supply and return ducts, registers, and the main trunk line. The job takes about three hours. What makes Union City different is the construction era: thousands of homes went up fast in the 2000s, and a lot of duct joints were never properly sealed. That means attic dust, insulation fibers, and pollen pour into the system through gaps the original builder never addressed. Our job is removing what’s already in there and showing you what needs sealing so it doesn’t come right back.
Source Removal, Not Just Brushing
We use source removal, which means physically agitating debris loose with a Rotobrush system while the entire duct run stays under negative pressure from a HEPA-filtered vacuum. The debris exits through the vacuum, never through your supply registers. For flexible ductwork common in Union City builds, we use gentler brush heads and lower RPMs to clean thoroughly without risking tears at the joints. Then we run a camera through your main trunk and representative branch lines. You see what we see. That’s the whole point of the before-and-after photo documentation included with every job.
When Cleaning Alone Isn’t Enough
Here’s the pattern we see over and over in Union City subdivisions from the 2000s boom: a homeowner pays for duct cleaning, dust reappears within a month, and they assume the cleaner did a bad job. What actually happened is unsealed joints letting attic or crawlspace dust pour straight back in. In a 2005 subdivision off Flat Shoals Road, our crew found a central return pulling visible dust from an unsealed attic joint. We performed source removal with negative pressure and HEPA filtration, then camera inspection confirmed clean supply and return ducts. The homeowner noted immediate reduction in dust on registers, but the real fix was sealing that joint. If you’re in an older Union City home and dust returns fast, duct sealing may be the actual fix, not another cleaning. We’ll tell you straight, because our 365-Day Done Right Promise means we’d rather flag the real problem than sell you a repeat visit you don’t need.

AfterCommon HVAC Cleaning Problems We See in Union City Homes
- Unsealed duct joints from the 2000s boom. Fast construction left many joints taped or never sealed at all. Attic dust and insulation enter the system continuously, which is why some Union City homeowners see dust return within weeks of a cleaning.
- Mold and biofilm on evaporator coils. Union City’s hot, humid summers keep coils wet for months. Combined with near-year-round runtime on high-efficiency systems, that creates a biological film that restricts airflow and smells musty when the AC kicks on.
- Pollen-saturated duct interiors. Spring pollen from surrounding wooded areas penetrates even the tightest homes and gets trapped in ductwork. For allergy sufferers in Union City, that means symptoms flare indoors as much as outdoors.
- Flexible ductwork damage from aggressive cleaning. Cheaper cleaning methods use stiff brush heads and high speeds that catch and tear the flexible ducts common in 1990s-2010s builds. We see the aftermath: disconnected branches, collapsed runs, and homeowners paying thousands for duct replacement.
Pricing for HVAC Cleaning in Union City, GA
Here’s the straight answer on what honest HVAC Cleaning in Union City costs. A full-system cleaning runs $450 – $850 for most Union City homes. Evaporator coil cleaning alone runs $150 – $300. AC duct cleaning alone runs $300 – $500. These are whole-system prices, not per-vent. The industry’s coupon trick is a $49 teaser that turns into an $800 invoice by the time the tech counts every vent and every return. We don’t do per-vent pricing, and we never will. The price we hand you in writing before any work starts is the price on your final invoice. Home size, number of systems, and whether your ducts also need sealing are what actually move the number. Call (470) 408-4927 and we’ll give you a firm quote over the phone before any tech steps onto your property.

FAQs About HVAC Cleaning in Union City
Because the construction pace of that era prioritized speed over detail, and duct joints were often left unsealed or loosely taped. Those unsealed joints allow attic dust, insulation fibers, and humidity to enter the system continuously. We find this pattern across Union City subdivisions built between roughly 1998 and 2012, far more often than in older, neighboring municipalities. If your ducts show signs of dust returning within weeks of a cleaning, sealing is likely the real fix. Call (470) 408-4927 and we’ll confirm with a camera inspection before recommending anything.
Every two to four years is realistic for most Union City homes, with annual checks on high-efficiency systems that run nearly year-round. Union City’s hot, humid summers and significant spring pollen mean systems accumulate debris faster than in drier climates. But honest answer: if your home has good filtration, no pets, and sealed ducts, you might stretch that longer. If you have allergies, multiple pets, or a 2000s-era home with unsealed joints, every two years is reasonable. We’ll tell you after a camera look whether your ducts actually need it now or not.
Per system, always. One flat price for the entire duct system, agreed in writing before we start. We never price per vent, and we encourage you to be wary of any Union City company that does. Per-vent pricing is how a $49 coupon becomes an $800 surprise. Our full-system price covers all supply runs, return runs, registers, and the main trunk line, and it doesn’t change at the door.
Yes, but it requires gentler equipment and more patience than rigid metal ducts. Union City’s 1990s and 2000s homes almost universally use flexible ductwork, which tears easily if hit with stiff brushes at high speed. We use lower RPM brush heads, softer bristle configurations, and controlled negative pressure. Camera inspection before and after confirms the job was done without disconnections or tears. If a duct is too fragile to clean safely, we’ll tell you that too, because sending debris down a broken run helps no one.
Yes. Every job includes before-and-after photo documentation of your actual ducts, not stock photos from another house. You’ll see your main trunk, your coil, and representative branch lines before cleaning and after. The photos arrive with your digital invoice, which you can pay from a link on your phone. That’s The Relay Standard, and it’s non-negotiable on every job we do in Union City.
