Rooted in Newfane, NY, Great Bison Heating & Cooling is a local air conditioning contractor that homeowners around the area lean on when their cooling acts up. Our team handles AC trouble of every kind, from refrigerant leaks and frozen coils to failing compressors, thermostat glitches, and weak airflow. As a certified, exclusive Mitsubishi Diamond Dealer, we always pair honest diagnoses with repairs that actually hold up.

You know the feeling. It's a sticky afternoon, you walk past a vent expecting a wave of cool air, and instead you get a lukewarm breeze that does nothing. Maybe your unit's running, but the house won't drop below muggy, or it's making a racket, leaking water, or blowing the breaker every time it kicks on. Whatever it's doing, a struggling AC turns a hot day into a long one in a hurry.
Plenty of things can be behind it. Low refrigerant from a slow leak is common, as is a frozen coil, a worn-out capacitor, or a compressor that's starting to give up. Other times it's a clogged filter choking off airflow, a dirty coil, or a thermostat sending the wrong signal so the system never cools the way you set it. Some of these are quick fixes, and some need a closer look, but they all leave you sweating until they're sorted.
When you call us, we don't start swapping parts and hoping. One of our techs comes out, listens to what you've noticed, and works through the system step by step, checking refrigerant levels, airflow, electrical components, and the thermostat until we find the real culprit. Once we know what's going on, we explain it in simple terms, give you the cost up front, and handle the repair on the spot whenever we can.
When we're done, cool air is moving through your house again, holding the temperature you set room to room. The strange noises quiet down, the unit stops icing up or short-cycling, and you get back to enjoying your summer instead of fighting with your AC to do its job.
Our AC repair services help homeowners identify the source of cooling issues, fix the right problem, and get their homes feeling comfortable again.

Pinpointing the real problem is where good repair work starts, so we walk through the entire system rather than guessing. When your air conditioner isn't working, our crew rules out causes one at a time until we land on exactly what's keeping the cool air from flowing.
Cooling tends to quit at the worst possible time, which is why we take emergency calls when the heat is bearing down. Our air conditioning repair service moves quickly, so your family isn't stuck sweating it out while you wait.
Weak airflow and uneven temperatures usually point to something behind the scenes working harder than it should. Clogged filters, blocked ducts, and struggling blower components all make our checklist when the AC isn't blowing cold air the way it used to.
The compressor and capacitor do much of the heavy lifting in your system, and when one starts to fail, cooling drops off quickly. We test these components, handle the air conditioner repairs they need, and get your unit running strong again.
A coil caked in ice might look strange, but it's a common reason an AC isn't cooling the way it should. We thaw things out, track down what caused the freeze-up, whether it's airflow or refrigerant, and fix the root of the problem so it doesn't ice over again.
Low refrigerant often hides behind weak cooling, and topping it off without finding the leak only kicks the can down the road. Our air conditioning repair work includes locating leaks, sealing them, and recharging the system to the proper level.
Sometimes the AC is fine, and a faulty thermostat is the real troublemaker, sending the wrong signals and throwing everything off. We check the settings, wiring, and calibration to make sure your system is getting the message to cool your home.
Once the main fix is handled, we make sure the whole system is actually performing as it should. Tuning airflow, checking temperatures, and confirming steady operation rounds out our air conditioner service so your home stays comfortable.

A broken AC during a New York heat wave can become urgent fast, especially for older folks, young kids, or pets who are sensitive to the heat. If your home is climbing into uncomfortable or unsafe temperatures, that's a good reason to call for emergency AC repair. Otherwise, a same-day or next-day appointment usually does the trick.
Warm air from your vents often indicates low refrigerant due to a leak, a dirty filter choking airflow, a frozen coil, or an incorrectly set thermostat. Some of these are quick fixes, while a refrigerant leak needs a technician to find and seal. Catching it early keeps your system from straining and incurring more extensive repairs.
Start by checking your thermostat settings and your breaker panel, since a tripped breaker is a surprisingly common and easy fix. Swap out a clogged filter if it looks dirty, and give the unit a few minutes to reset. If it's still blowing warm or not running, call for AC repair and try to keep your home cool with fans and closed blinds in the meantime.
A frozen AC usually stems from restricted airflow due to a dirty filter, blocked vents, or low refrigerant levels. When ice builds up on the coils, the system can't cool properly and may shut down to protect itself. Turning it off to let the ice melt helps in the short term, but a technician should determine why it's happening to prevent it from recurring.
Odd sounds from an AC can mean different things, like a buzzing electrical issue, a rattling loose part, or a grinding motor that needs attention. A little hum is normal, but banging, screeching, or clicking usually signals something worth checking out. Getting it looked at early often prevents a small problem from turning into a full breakdown.
