When your air conditioner limps through a Tempe summer because of a frozen or leaking evaporator coil, Arizona Refrigeration Service Inc. is only 4 minutes from Downtown Tempe. Our shop on W 1st St lets us reach Mill Avenue lofts, Tempe Town Lake, and ASU dorms fast for dependable AC coil repair.
Ice glazing your outdoor lines, weak airflow inside, or a sudden spike on your SRP bill often trace back to a damaged evaporator coil. Because the coil absorbs indoor heat, tiny refrigerant leaks, dirt buildup, or corrosion will leave rooms muggy and the compressor overworked. If you notice warm air or puddles beneath the air handler, schedule professional coil service before the system suffers costly compressor damage. Our technicians pinpoint leaks and deliver precise refrigerant leak repair so your home cools evenly again.
Living steps from Papago Park or in student housing near ASU means triple-digit afternoons that punish HVAC equipment. When you call before 3 p.m., we promise same-day arrival from our Tempe headquarters. GPS routing guides the closest stocked van down Rio Salado Parkway, keeping average door-to-door time under 25 minutes.
Once onsite, a background-checked technician disconnects power, removes the blower panel, and inspects the coil with a UV dye light. Meg-ohm and nitrogen pressure tests expose hairline leaks invisible to the naked eye. If damage is isolated, we braze copper fins, install new Schrader cores, evacuate the system to 500 microns, then weigh in the exact factory refrigerant charge. For severe corrosion we can quote full coil replacement or discuss cost-effective system upgrades.
After repairs, we balance airflow, sanitize condensate pans, and photograph pressure readings inside our digital portal so you can view “before” and “after” performance from your phone. Every job is protected by a one-year labor warranty, and we never add evening or weekend surcharges. That transparency has made Arizona Refrigeration Service Inc. the logical choice for homeowners from Kiwanis Park to West Tempe since 1982.
To avoid repeat breakdowns, we schedule a discounted follow-up AC maintenance visit at your convenience, ensuring the coil remains clean, efficient, and ready for monsoon humidity.
Whether your townhouse near Tempe Marketplace loses cooling after a late-night shopping trip or your ranch home in South Tempe struggles with humidity, our coil specialists have your back. Because our facility sits at 820 W 1st St, we can cruise Apache Boulevard, Rural Road or the Red Mountain Freeway to reach any address in minutes—without tacking on mileage fees.
Homeowners appreciate 7 a.m. to 7 p.m. scheduling, but if a coil rupture leaves the system hissing at 10 p.m., our emergency AC repair line still answers. Each van carries nitrogen kits, deep-vac pumps, fin straighteners and OEM expansion valves, so most AC coil repair jobs finish the same night.
We also provide preventative HVAC maintenance and full system installations for remodels around ASU or new builds in Kiwanis Park. Whatever zip code you call home, you receive the same logical pricing, documented workmanship and one-year labor guarantee that define our brand promise.
From high-rise apartments overlooking Tempe Town Lake to historic bungalows in Downtown Tempe, we respect HOA rules, secure rooftop permits and photograph every step for your records. Our team recovers and recycles refrigerant responsibly, protecting the Salt River watershed while keeping your indoor climate comfortable.

Warm air often indicates the evaporator coil is frozen, dirty or leaking refrigerant, so it cannot absorb household heat. Even with a clean filter, restricted airflow or low charge turns the indoor coil into an ice block that insulates rather than cools. Our technician will thaw the coil, check static pressure, locate leaks with electronic detectors and restore the proper charge, bringing cold air back within one service visit quickly.
Because our office is on 1st Street, vans already cruise South Tempe neighborhoods like Kiwanis Park all day. During declared emergencies we skip routine calls and reroute the closest technician, usually arriving within 25 minutes. Each truck carries nitrogen, UV dye and copper fittings, so a pinhole coil leak can be isolated, brazed and recharged on the first trip, getting your family safe from 110-degree temperatures before sunset this summer.
Cost effectiveness depends on coil age, system efficiency and refrigerant type. If your unit uses modern R-410A, the cabinet is rust-free and the compressor readings are healthy, repairing a small leak is usually 30 to 50 percent cheaper than total replacement. However, if corrosion is widespread or the compressor shows high amperage, upgrading to a new high-SEER system can save energy and qualify for rebates. We present options with pricing.
Start by changing filters monthly, keeping return vents unblocked and arranging annual professional coil cleaning. Pour a cup of vinegar in the condensate line every other month to deter algae that can back up water and soil the coil. Maintain two feet of clearance around outdoor condensers to improve airflow. Finally, consider installing a filter or UV purifier to trap dust and microbes that would otherwise accumulate on coil surfaces.
Yes. When a leaking or dirty coil forces longer runtimes, the compressor draws more amperage, inflating kilowatt hours. After repair, the coil absorbs heat efficiently, allowing shorter cycles, and lower head pressure. Customers in Downtown Tempe typically see five to ten percent reductions, which can cover repair costs within peak-summer billing periods. Savings grow further when coupled with thermostat optimization and sealing any duct leaks discovered during our inspection today.
