COMMON CAUSES & SOLUTIONS

🌡️Normal

Extreme Arizona Heat

On 110°F+ days, even a properly functioning AC may run 80–90% of the time. This is normal. If your home is reaching the set temperature, your AC is working correctly.

🌡️High

Refrigerant Leak

Low refrigerant reduces cooling capacity, causing the system to run constantly without reaching the set temperature. Bradford diagnoses and repairs refrigerant leaks.

🧹Medium

Dirty Condenser Coil

A dirty outdoor condenser coil can't release heat efficiently, reducing cooling capacity by 20–30%. Bradford cleans condenser coils as part of a $59 tune-up.

📐Medium

Undersized AC System

An undersized AC can't keep up with Arizona's heat load. Bradford can assess your system sizing and recommend the right replacement.

🏠Medium

Poor Attic Insulation / Air Sealing

Arizona attics can reach 160°F. Poor insulation allows heat to radiate into your living space faster than your AC can remove it.

🌬️Medium

Duct Leaks

Leaky ducts in Arizona attics lose 20–30% of cooled air into the attic. Bradford offers duct sealing and replacement to fix this.

An AC that runs constantly in Arizona's extreme heat is often a sign of an undersized system, refrigerant leak, dirty coils, or a failing compressor.

Bradford is locally owned by Ken Bradford Baker, licensed AZ ROC# 353859, with 4.8 stars from 304+ verified Google reviews. Bradford charges $0 for the service call with any approved repair.

FREQUENTLY ASKED QUESTIONS

On days above 105°F, it is normal for your AC to run 80–90% of the time. However, if your home is NOT reaching the set temperature despite constant running, something is wrong. Common causes include refrigerant leak, dirty condenser coil, undersized system, or duct leaks. Call Bradford at (623) 624-6246 for a diagnosis.
If your AC is running constantly but not cooling, the most common causes are: (1) refrigerant leak, (2) dirty condenser coil, (3) undersized system, (4) duct leaks, (5) poor attic insulation. Bradford diagnoses the cause same-day and provides a written upfront quote.
The cost depends on the cause: refrigerant recharge ($200–$600), condenser coil cleaning ($100–$200), duct sealing ($500–$1,500), new system if undersized ($7,500–$14,000). Bradford waives the service call fee with any approved repair.
Yes. A clogged air filter restricts airflow, reducing cooling capacity and causing the system to run longer. Replace your filter first. If the AC still runs constantly without cooling your home, call Bradford.
Most Arizona homeowners set their thermostat to 78–80°F during the day and 72–76°F at night. Setting it lower than 78°F in summer can cause the AC to run constantly and may not be achievable on 110°F+ days. Bradford recommends setting your thermostat to the highest comfortable temperature to reduce runtime and energy costs.
Yes. Bradford offers same-day service in Surprise, Peoria, Glendale, Goodyear, Buckeye, Sun City, and Sun City West. Call (623) 624-6246.
Yes. Duct leaks in Arizona attics (which reach 160°F) can lose 20–30% of cooled air into the attic, causing your AC to run constantly without cooling your home. Bradford offers duct sealing and duct replacement to fix this.
Keep your air filter clean (replace every 1–3 months). Close blinds and curtains on south/west-facing windows. Run ceiling fans to feel cooler at higher temperatures. Schedule a $59 Bradford tune-up to clean the condenser coil and check refrigerant levels. Consider a programmable thermostat to raise the temperature when you're away.
