It is 95 degrees outside, your system is blowing warm air, and every hour without AC means lost customers or miserable employees

Grinding, banging, burning smell — your system is warning you. Ignoring it turns a $300 repair into a $5,000 replacement

FAQ
Questions We Hear Every Day
Honest answers from licensed HVAC technicians.
How much does HVAC repair cost depends on the failure: a capacitor swap or refrigerant top-off typically runs $150–$350, while a compressor replacement on a rooftop split can reach $1,200–$2,500. Labor rates in the five boroughs tend to be 20–30% higher than national averages. Diagnosing the root cause before pricing anything is always the right first step.
What is HVAC repair? It's the process of diagnosing and correcting a mechanical, electrical, or refrigerant failure in a heating or cooling system. For an AC unit, that might mean replacing a failed contactor, recharging refrigerant to manufacturer spec, clearing a blocked condensate line, or repairing a burnt blower motor — whatever is keeping the system from conditioning air properly.
HVAC blowing cold air when heat is on usually points to one of a few things: a tripped limit switch from overheating, a failed ignitor or flame sensor on a gas furnace, or a heat pump stuck in cooling mode due to a faulty reversing valve. On older NYC buildings with steam or hot-water heat, a stuck zone valve or failed circulator pump is the more likely culprit.
Knowing how to test HVAC blower motor with multimeter correctly saves time: set the meter to AC voltage and confirm 120V or 240V at the motor terminals, then switch to resistance mode and check each winding. A healthy winding reads a few ohms; open reads OL; shorted reads near zero. Also check the run capacitor — a degraded cap mimics a failed motor and costs far less to replace.
Why is my HVAC not cooling is one of the most common calls in summer. Low refrigerant charge (often from a slow leak), a dirty condenser coil blocking heat rejection, or a frozen evaporator coil from restricted airflow are the top three causes. A rooftop packaged unit in direct Manhattan sun can also short-cycle if the high-pressure switch trips repeatedly. Start by checking the air filter.
