Licensed HVAC contractor repairing air conditioners for Germantown homes
A struggling air conditioner rarely waits for a convenient afternoon to fail, and in a Memphis area summer, every hour without cooling matters. Since 2014, we at Infinity Heating and Air Conditioning have sent technicians into Germantown homes to track down the exact reason a system stopped cooling, whether that means a refrigerant leak, a frozen coil, or a thermostat that has simply quit communicating with the unit.

Refrigerant Leak Detection and Repair: A system that cools well for a few hours and then fades is often losing refrigerant through a small leak in the line set or coil. We pressure test the system, locate the leak, repair it, and recharge to the manufacturer’s specification.
Frozen Evaporator Coil Repair: Ice on the indoor coil usually points to restricted airflow or low refrigerant, and running the system with a frozen coil can damage the compressor. Our technicians thaw the coil safely, then trace the root cause before turning the system back on for good.
Thermostat Diagnostics and Repair: When a thermostat stops communicating with the outdoor unit, the AC can run constantly, short cycle, or not start at all. We test the thermostat’s wiring and control board separately from the equipment itself, since replacing the wrong part rarely fixes the actual problem.
Airflow and Duct Diagnostics: Warm spots in some rooms while others stay cool often trace back to a blocked return, a collapsed duct section, or a filter that has restricted airflow for months. We check the whole air path from the return grille to the supply vents.
Unusual Noise Diagnosis: Grinding, rattling, or a new humming sound almost always signals a specific mechanical cause, whether that is a failing fan motor, a loose panel, or a compressor under strain. We identify which component is making the noise before recommending a repair.
Same Day Emergency AC Repair: A no-cool call in the middle of a Germantown heat wave gets priority scheduling, and our technicians carry the parts most commonly needed for repairs so a same day fix is possible more often than not.
Capacitor and Electrical Component Repair: Start and run capacitors wear out gradually and then fail all at once, often during the hottest stretch of summer when the compressor is working hardest. We test capacitor performance during every AC repair visit and can review AC replacement options if the compressor itself has failed.
Preventative Maintenance and Tune Ups: Many of the repair calls we run start as a small issue that a spring or fall tune up would have caught early. Residential and commercial customers across Germantown and the surrounding Shelby County suburbs can cover two tune ups a year, along with a repair discount, through the Infinity Plus Plan.
Germantown summers do not just get hot, they stay hot for months without much overnight relief. According to the National Weather Service Memphis office’s 1991 to 2020 climate normals, the city’s average high climbs into the low 90s from June through August, while overnight lows barely dip into the low 70s. That narrow gap between day and night temperatures means an air conditioner rarely gets the extended rest period milder summers allow elsewhere.
Long compressor run times are the direct result. When an AC unit cycles on for hours at a stretch instead of running in short bursts, moving parts like the compressor motor and the start capacitor absorb far more wear than the same equipment would see in a typical spring or fall. That sustained strain is exactly why capacitor failures often disable a compressor at the peak of a Germantown heat wave, sometimes stopping cooling completely just when a home needs it most.
The same conditions create problems inside the system itself. High humidity paired with continuous run times means the evaporator coil pulls moisture out of the air almost nonstop, and any restriction in airflow, whether from a dirty filter or low refrigerant, gives frost time to build up on the coil instead of draining away as normal condensation. A frozen coil can quickly overwhelm the condensate line and send water backing up into the drain pan or beyond it.
When we diagnose an AC repair call in Germantown, we treat run time and airflow as the starting point, not an afterthought. Checking refrigerant charge, capacitor condition, and coil ice buildup together tells us whether a system failed because of a single bad part or because months of Memphis area heat wore down more than one component at once.

When an air conditioner will not hold its charge, needing a specific replacement part can turn a same day fix into a multi day wait. Deidre Ross ran into exactly that problem, and instead of settling for a delayed appointment, found Micah unwilling to let a part shortage become her problem to solve.
“Excellent service and friendly techs! Micah went out of his way to make sure my AC was in good working order. He arrived promptly, diagnosed the issue, and even though he thought it would be several days before he could return with the necessary part, he hunted one down and repaired my unit the same evening. I will definitely keep them in my contacts for future reference.”
Tracking down a hard to find part on the same day is not the exception at Infinity Heating and Air Conditioning, it is the standard we hold every repair call to. Read Deidre’s full Google review.
Not every AC repair call goes smoothly from the first phone call, and customers can sometimes feel like they are getting a different level of service than the one promised. Mr. Lewis expected a certain amount of runaround from a technician he had never met, and was pleasantly surprised when that never came.
“My service was completed by Clayton from Infinity. Great customer experience from the initial phone call to the end of service. Had my system back up and running. Provided proper education. Didn’t call me an old man no matter how much I baited him.”
That same respect and plain explanation of the problem is part of how every Infinity Heating and Air Conditioning technician is trained to handle a repair call, regardless of who answers the door. Read Mr. Lewis’s full Google review.

Whether your system stopped cooling overnight or has been struggling to keep up for weeks, our technicians can diagnose the cause and walk through repair options before any work begins. Book online with Infinity Heating and Air Conditioning, check our Germantown service area coverage, or ask about the Infinity Plus Plan to catch small problems before they turn into a no-cool emergency.
If your system is running constantly, blowing warm air, making a new grinding or clicking noise, or tripping the breaker, those point to a mechanical or electrical issue rather than a dirty filter. A stuck thermostat display or ice on the indoor coil are also signs that call for a technician rather than a simple filter swap.
We check refrigerant charge and pressure, inspect the capacitor and electrical connections, test the thermostat’s communication with the system, and look at airflow through the coil and ductwork. Most Germantown AC repair calls are diagnosed and quoted in a single visit.
In many cases yes. We locate the leak, repair or replace the affected line or coil section, then recharge the system to the manufacturer’s specification. A leak that has damaged the compressor is one of the few situations where replacement makes more sense than another repair.
We look at the age of the system, the cost of the needed repair, and whether the refrigerant it uses is still widely available. A unit under warranty with a single failed part usually gets repaired, while a compressor failure on a system already past a typical 12 to 15 year lifespan is often better replaced.
Germantown sits in the same humid climate the National Weather Service tracks for the whole Memphis area, where summer highs regularly reach the low 90s and overnight lows barely drop into the low 70s. That narrow day to night swing keeps compressors running for extended stretches, which is exactly the kind of strain that leads to capacitor failures and frozen coils.
You can book online and our team will schedule a technician to diagnose the problem, quote the repair, and get your system running again as quickly as the parts allow.
