AC Short Cycling: Why Your Air Conditioner Keeps Turning On and Off
AC turning on and off every few minutes? Here's what causes short cycling, what it's costing you, and what to check before you call for repair.

Professional ac repair for Grand Rapids homes and businesses. Mazure's Heating & Air Conditioning is just 15 minutes from our Jenison shop — fast response when you need it most.
Grand Rapids summers are humid. When your AC goes down on a 90-degree day, the house heats up fast — especially in the older neighborhoods where homes were built before air conditioning existed. We've been repairing air conditioners across Grand Rapids since 1987, from the stately homes in Heritage Hill to the bungalows in Eastown and the ranches in Alger Heights. We answer emergency calls 24/7, and our Jenison shop is about 15 minutes from downtown. Mike Mazure still answers the phone himself.
We regularly serve homes in Eastown, Heritage Hill, Midtown, Creston, Alger Heights, Westside — near Frederik Meijer Gardens and Van Andel Arena. Our Jenison headquarters puts us just 15 minutes from our Jenison shop, which means fast emergency response when your system goes down unexpectedly.
Adding central air to a home that wasn't built for it creates unique problems, and Grand Rapids has thousands of these homes. Heritage Hill's large Victorian and Colonial Revival homes have high ceilings, multiple floors, and ductwork that was shoehorned in during a later renovation. These systems work hard to push cool air through long duct runs, and the AC units attached to them tend to fail earlier than in homes with purpose-built ductwork. Frozen evaporator coils are common when ductwork can't deliver enough airflow. In Eastown and Midtown, Craftsman bungalows often have AC units from the early 2000s that are reaching end of life. Compressor failures, refrigerant leaks at the coil, and burned-out fan motors are the calls we get most often from these neighborhoods. Many of these homes also struggle with humidity because the AC system cycles too quickly to remove moisture from the air. On the Westside, the smaller cottages along Bridge and Leonard sometimes have oversized AC units that were installed without proper sizing calculations. An oversized system cools the house in 10 minutes, shuts off, and the temperature rebounds quickly — leaving the homeowner feeling like the AC isn't working even though it technically is. Alger Heights and the Southeast Side have more standardized ranch-style homes where AC repair is usually more straightforward, but these units are aging and we see a lot of capacitor and contactor failures in the 15- to 20-year-old systems common in those neighborhoods.
Every AC repair call starts with an honest diagnosis. Our technician checks refrigerant levels and pressures, inspects the compressor, tests capacitors and contactors, examines the evaporator and condenser coils, and measures airflow. In Grand Rapids' older homes, we also check the ductwork for leaks and restrictions that can mimic equipment failure. A system that's low on refrigerant might have a slow leak at a coil fitting that's been losing charge for two summers. We find the actual problem, not just the symptom. Once we know what's wrong, we give you the price before touching anything. Most AC repairs in Grand Rapids run between $150 and $600. A capacitor replacement is quick and on the low end. A compressor replacement on an older system is on the high end, and at that point we'll give you the honest math: does it make sense to put $600 into a 17-year-old system, or would that money be better applied toward a new unit? We lay out both options and let you decide. We don't earn commissions on new equipment sales, so our technicians have no incentive to push replacement over repair.
Extreme heat is a health risk, not just a comfort issue. Seniors, children, and people with medical conditions can be seriously affected when indoor temperatures climb above 85°F. We offer round-the-clock emergency AC repair for every Grand Rapids neighborhood. Our response time to downtown Grand Rapids, Heritage Hill, Eastown, and the Westside is typically 30 to 45 minutes. Creston, Alger Heights, and the Southeast Side are 35 to 50 minutes depending on traffic. When you call after hours, you reach a real person who can dispatch a technician. We stock the most commonly failed parts on our trucks — capacitors, contactors, fan motors, and hard-start kits — so many emergency repairs are done on the spot. We charge the same diagnostic fee for after-hours calls as we do during business hours. Parts prices don't change either. Some Grand Rapids HVAC companies double their rates for evening and weekend service. We think that's wrong. If your AC breaks at 11 PM, you're already having a bad night — we're not going to make it worse with inflated pricing. Call (616) 669-8085 any time.
