Our FAQ
How often should I service my air conditioner?
Once a year, ideally before the weather turns. PTAC units run hard through summer, and a pre-season check catches worn parts before they fail mid-heatwave.
What qualifications and certifications do City Cool advisors have?
Our technicians are licensed HVAC professionals with hands-on PTAC experience across NYC properties, not call-center reps reading off a script.
How is a mini split different from a window AC unit?
A mini-split is a permanent, ductless system with an outdoor compressor and one or more indoor units - quieter, more efficient, and built to last far longer than anything sitting in a window frame.
Do mini-splits work for heating too?
Most modern systems are heat pumps, meaning they heat and cool from the same unit - a real advantage for smaller NYC apartments without separate heating zones.
Is a smart thermostat worth it for my home?
For most households, yes - better scheduling and lower energy use over time. But compatibility with your existing HVAC system matters more than the brand you pick.
Can you install a smart thermostat with my old HVAC system?
In most cases, yes. We check compatibility first so the new thermostat actually works with your existing setup instead of fighting it.
What's the actual benefit of switching to a smart thermostat?
Certain benefits, such as better scheduling and noticeably lower energy waste over time, can be gained if you switch to a smart thermostat.
Can any smart thermostat work with any HVAC system?
No. Older systems especially need a compatibility check first. Skip that step, and you risk short-cycling instead of solving
How often should a water source heat pump be serviced?
Once a year, ideally before peak season. Catching a small issue early is a lot cheaper than replacing a burned-out compressor mid-summer.
Can a fan coil be repaired, or does it need full replacement?
Most issues such as motors, coils, and condensate lines are repairable. Replacement usually only comes up when the unit is old enough that repeated failures start piling up.
