ASKED QUESTIONS
How long has Adams Refrigeration been in business?
Since 1947. We are a family-minded, locally owned Phoenix company, and we have served homes and businesses across the Valley for more than 75 years.
Are you licensed?
Yes. Adams Refrigeration holds Arizona ROC license 245268. We are also an APS Qualified Contractor and a BBB Accredited Business.

Yes. We are a Carrier Factory Authorized Dealer and have won Carrier’s President’s Award several times, which recognizes dealers for service, installation quality and customer care. See our awards and certifications.
Are your technicians paid on commission?
No. Our technicians are paid hourly, so there is no reason for them to push a sale. They recommend the repair or replacement that makes sense for your system and your budget.
Are your technicians NATE certified?
Our team includes NATE-certified technicians. NATE (North American Technician Excellence) is the HVAC industry’s leading certification for technicians.
Which areas do you serve?
Phoenix and the surrounding Valley, including Glendale, Peoria, Sun City, Surprise, Avondale, Goodyear, Litchfield Park, Buckeye, Tolleson, Chandler, Gilbert and Tempe. See all service areas.
Can I reach you after hours?
Yes. Our phone line is open 24 hours a day, every day. Call (602) 269-6447 and describe what your system is doing.
How do I book a visit?
Call (602) 269-6447 or schedule an appointment online. Tell us the make of equipment if you know it and what the system is doing, so the technician arrives with the right parts.
Will I know the price before you start?
Yes. The technician explains what failed and gives you the price before replacing any part. You decide whether to go ahead.
Do you work for businesses and commercial buildings?
Yes. We repair and maintain commercial rooftop units and split systems, and we set up scheduled maintenance visits for businesses so filters and coils are serviced on a regular cycle.
Do you work with landlords, property managers and realtors?
Yes. We coordinate access with tenants, send the owner the diagnosis and price, inspect systems before a sale and keep a service history for each property.
Can I buy HVAC parts and supplies from you?
Yes. We sell parts and supplies to homeowners who want to handle simple jobs themselves. Call (602) 269-6447 with the model number of your unit and we will check what we have.
When should I get my heating and cooling serviced?
Before each season: the air conditioner in spring, before the first 100-degree week, and the heating in fall. Our AC tune-up checks the electrical parts, coil, refrigerant charge and drain.
My AC is running but not cooling. What should I check first?
Make sure the thermostat is set to cool, the breaker for the outdoor unit is on and the filter is clean. If the outdoor unit hums but its fan does not spin, turn the system off and call, because running it that way can damage the compressor.
Why is my air conditioner making noise? Can I fix it myself?
Please do not open the unit yourself. Buzzing, clicking or grinding usually points to an electrical part or motor, and the outdoor unit carries high voltage. Turn the system off and contact us or see AC repair.
What thermostat setting is best for summer?
We suggest 72 degrees with the fan set to AUTO while you are home, so the system can remove humidity between cycles. Raising the setting a few degrees when you are away lowers your power bill.
How often should I change my air filter?
Every one to three months during cooling season. Change it more often if you have pets, allergies or construction nearby. A clogged filter can freeze the indoor coil and shorten the system’s life.
Do you service evaporative coolers?
Yes. We repair and maintain evaporative coolers, including pads, pumps and float valves, and can help you decide whether a home still running a cooler would be better served by refrigerated air.
What is a ductless mini split system?
A mini split cools and heats without ductwork. An outdoor unit connects to one or more wall-mounted indoor units through a small hole in the wall. They work well for additions, garages and rooms the main system cannot reach. See mini split installation.
Should I repair or replace my air conditioner?
It depends on the system’s age, the cost of the repair and how often it has failed. When a system is older, we give you the repair price and a replacement price at the same visit. Read AC repair vs replacement for more.
My system uses R-22. What does that mean for me?
R-22 has not been produced since January 1, 2020, so the remaining supply is limited and expensive. A small repair can still make sense, but a major leak on an R-22 system is usually the point to replace it.
What efficiency rules apply to a new system in Arizona?
New split air conditioners in the Southwest must meet at least 14.3 SEER2, and new equipment built since 2025 uses A2L refrigerants such as R-454B. We size every system with a load calculation rather than copying the old unit’s size.
Is maintenance included with a new system?
Yes. Every new unit you purchase from Adams Refrigeration includes three years of maintenance at no extra cost.
Do you offer financing?
Yes. Through Wells Fargo, we offer flexible financing on new Carrier systems. See financing options or ask your technician during the estimate.
Do you handle permits for a new system?
Yes. We file the permit with your city and schedule the inspection as part of the installation. See AC installation.
