How Much Money Can a New Air Conditioner Save You?

Our SEER2 (Seasonal Energy Efficiency Ratio 2) energy savings calculator can help determine how much you could save on your utility bills. Simply enter your current unit’s SEER value and compare it to a newer, more efficient SEER2 unit. You can even customize it to better match your home’s system for a more accurate calculation.

AC Installation & Replacement

A new AC makes sense when repairs keep adding up, energy bills keep climbing, or the system is nearing 15 to 20 years old. The team at McCall’s Air Conditioning and Heating walks you through your options without a sales pitch and installs your new system without delay, with financing available for approved credit.

• Units nearing 15–20 years old, especially units that have sat in un-shaded Arizona attics. Efficiency drops fastest in the final years of a system's life, and Arizona's heat load accelerates that wear compared to milder climates. Acting before a full breakdown gives you time to plan the replacement instead of scrambling in July.
• Repeated repairs on the same unit. Fan motors, capacitors, circuit boards: these are the components we replace most often on aging systems here. If you've had more than one repair call in a season, it's worth comparing that repair cost against a new system.
• Uneven cooling or rooms that never quite reach temperature. This is often a duct-balancing issue rather than the unit itself. Our team can diagnose whether it's the equipment or the ductwork before you spend money on the wrong fix.
• Rising energy bills with no change in your utility rate. This usually means your system is running longer to reach the same comfort level than it used to.

If you notice any of these signs, or suspect another reason for needing a replacement, talk to one of our McCall's team members. We'll design a system matched to your comfort needs and budget.

We also offer several financing options, with approved credit, to help if this is a concern. Contact us to discuss how our team can guide you through our process.

AC Repair, Available 24/7

When an AC stops cooling, the cause is usually a failed fan motor or capacitor, a refrigerant or compressor problem, or a frozen coil. Technicians from McCall’s Air Conditioning and Heating are available 24/7 and make every repair right the first time with quality parts.

Here's what we typically find when a Mesa AC unit stops cooling properly:

• A failed or failing fan motor. This is one of the most common repairs we make on units that have run through multiple Arizona summers
• A bad capacitor, often the culprit when a unit hums but won't start
• Warm air from the vents, which can mean anything from a refrigerant issue to a failing compressor
• A frozen coil, usually from restricted airflow or a refrigerant problem
• Water leaking near the unit, which can damage drywall and flooring if left alone

Ignoring problems usually only makes them bigger and more costly. Our recommendation is to have one of our McCall's team members promptly diagnose and repair the issue for you.

Mesa AC Repair & Replacement Questions, Answered

Why is my AC running but not cooling my Mesa home?

An AC that runs but blows warm air usually has a dirty filter or coil, low refrigerant, a failed capacitor or compressor, or a frozen evaporator coil. In a Mesa summer, a unit that runs all day and still can't catch up often points to one of those problems or to leaky ductwork. Check the filter first, and if the air stays warm, McCall’s Air Conditioning and Heating can diagnose the cause so you pay for the right fix.

Why does my AC keep freezing up?

Ice on the indoor coil or refrigerant line usually comes from restricted airflow or low refrigerant. A clogged filter, a weak blower, or a refrigerant leak are the usual causes. Turn the system off and let the ice melt completely before running it again, since running a frozen coil can damage the compressor. A leak or airflow problem will freeze it again, so the underlying cause needs a repair. Regular maintenance plans catch dirty coils and weak airflow before they freeze the system.

What is short cycling, and why does my AC keep turning on and off?

Short cycling means the AC shuts off before it finishes a normal cooling cycle, then restarts a few minutes later. Common causes include an oversized system, a dirty filter or coil, a refrigerant problem, or a thermostat issue. It wears out parts quickly and leaves the house humid and uneven, so it's worth diagnosing early.

How much does an AC repair cost in Mesa?

Cost depends on the part and the labor involved. A capacitor or contactor sits at the low end, while a compressor, evaporator coil, or refrigerant leak repair costs more. Refrigerant type and the age of the system also affect the price. McCall’s Air Conditioning and Heating diagnoses the problem first and explains the repair options before any work starts.

Should I repair or replace my AC?

Repair usually makes sense for a newer system with a single failed part. Replacement is the better call when the unit is 15 years or older, repairs keep adding up, or cooling and energy bills are getting worse each summer. One rule of thumb is to multiply the system's age by the repair quote, and if the result is over $5,000, replacement is usually the smarter investment. A technician can also check ductwork and sizing, since a new unit paired with leaky ducts won't deliver the improvement you're paying for.

How much does AC replacement cost, and when is the best time to replace?

Replacement cost depends on the home's size, the system's efficiency rating, the equipment brand, and whether ductwork needs work. Replacing in spring or fall, before the peak heat arrives, avoids waiting on a system that failed in July. McCall’s Air Conditioning and Heating walks through your options in writing, and financing is available for approved credit.

How long does an AC last in Arizona?

Many Arizona systems wear out sooner than the national 15 to 20 year range, because summer runs the compressor for months at a time. Regular filter changes, clean coils, and annual service help a system reach the long end of that range.

Do you offer emergency AC repair in Mesa?

Yes. McCall’s Air Conditioning and Heating technicians are available 24/7 for AC repair across Mesa and the East Valley, so a failed system in the middle of a summer night doesn't have to wait until morning.
