Heating and air conditioning service built around Mount Hermon
We keep licensed, background-checked technicians on the road in Mount Hermon and the surrounding 42157 service area, so a no-cool or no-heat call usually gets a same-visit fix rather than a return trip.
Because Kentucky swings between seasons quickly, a lot of our Mount Hermon calls come in the first hot or cold snap of the year — systems that sat idle for months and then get asked to run flat out.
If your system is over ten years old and you have had two repairs in the last two seasons, a replacement comparison is usually worth running even if the current unit still runs.

Mount Hermon42157 HVAC questions, answered
What causes water to leak from the indoor unit?
Almost always a blocked condensate drain line, a failed drain pan float switch, or a frozen coil melting faster than the pan can handle. In Mount Hermon we see algae and dust clogging drain lines constantly during May through September. It is a fast fix but ignoring it ends in ceiling damage.
Should I repair my system or replace it?
The usual rule of thumb: if the repair costs more than half the price of a replacement and the equipment is over ten years old, replacement generally wins. We will run that comparison with you on site and show you the maths — and if the honest answer is a $180 capacitor rather than a $9,000 system, that is the answer you get.
Are your technicians licensed and insured?
Every technician dispatched into Mount Hermon is licensed, insured and background-checked. We can provide proof of insurance on request before the visit if you would like it on file.
Is my system low on refrigerant, or is it leaking?
Refrigerant does not get "used up" the way fuel does. If your charge is low, there is a leak somewhere — usually at a flare connection, a schrader core or the evaporator coil. We locate and repair the leak rather than simply topping up the charge, because a top-up alone will fail again.
Do you handle ductless mini-split systems?
Yes. Ductless installations have grown quickly in Kentucky, particularly in older homes without existing ductwork. We service indoor heads, clean filters and drain lines, check line-set insulation and diagnose communication faults between heads and the outdoor unit.
Do you service commercial and light commercial properties?
Yes. Around Mount Hermon we handle rooftop packaged units, split systems, VRF/VRV installations and building automation faults for offices, retail, restaurants and multi-tenant buildings, including after-hours scheduling so you are not disrupting trade.
