Common AC Problems We Repair

At Shamrock Heating & Cooling, our experienced HVAC technicians are trained to troubleshoot and repair all types of air conditioning system issues. Whether your unit is showing signs of wear or has completely shut down, we’re here to help with reliable AC repair in Tempe, AZ.

We resolve a wide range of common and complex air conditioner problems, including:

Insufficient cooling or uneven temperatures: If your AC isn’t cooling your home evenly or certain rooms are hotter than others, it may indicate airflow restrictions, thermostat miscalibration, or a failing compressor.
Strange noises or foul odors from the unit: Rattling, buzzing, grinding, or musty smells can signal loose components, electrical issues, mold growth, or refrigerant leaks.
Refrigerant leaks or low refrigerant levels: Leaking refrigerant can reduce cooling efficiency, damage your compressor, and increase energy usage.
Frozen evaporator coils: Often caused by poor airflow, dirty filters, or refrigerant problems, frozen coils can lead to complete system shutdowns.
Faulty thermostats or inaccurate temperature control: Thermostat issues can cause frequent cycling, incorrect temperature readings, or total system failure.
Short cycling (frequent starting and stopping): This can stress your system, waste energy, and is often caused by sensor issues, thermostat problems, or dirty coils.
Water pooling around the indoor or outdoor unit: This may result from clogged condensate drains, broken condensate pumps, or frozen coils melting unexpectedly.

We service all major HVAC brands and models, ensuring your AC system gets back to running smoothly and reliably.

Frequently Asked Questions About AC Repair

How do I know if my AC needs repair?

Signs your air conditioner may need repair include uneven cooling throughout your home, unusually high energy bills, weak airflow from vents, strange noises like banging or buzzing, and unpleasant odors such as musty or burning smells. If your AC unit is short cycling, not reaching the set temperature, or simply not keeping your home comfortable during the Tempe heat, it’s time to schedule a professional AC repair service with Shamrock Heating & Cooling.

How long does an AC repair take?

Most AC repairs in Tempe, AZ can be completed within one to three hours, depending on the issue. Common fixes like thermostat replacements, capacitor changes, or refrigerant recharges are typically fast, while more complex problems involving motors, electrical components, or coil damage may require additional time. Shamrock Heating & Cooling works quickly and efficiently to diagnose and resolve your air conditioning problems as soon as possible.

Can I prevent frequent AC repairs?

Yes, regular HVAC maintenance is key to preventing frequent AC breakdowns and costly repairs. Changing your air filter regularly, scheduling annual AC tune-ups, and keeping your outdoor condenser unit free of debris can all help your system run more efficiently and last longer. We provide preventative maintenance plans to keep your air conditioner in peak condition throughout Tempe’s demanding summer months.

Is it better to repair or replace my AC?

If your air conditioner is over a decade old, needs constant repairs, or can no longer keep your home consistently cool, it may be time to consider upgrading to a newer, high-efficiency model that offers better performance and long-term savings. While repairs can fix short-term issues, an aging or inefficient system may continue to drain energy and rack up service costs. We can evaluate your current air conditioning system and help you decide if a repair or full AC replacement is the smarter long-term solution.
