The Corunna46730 calls we answer most often
If your system is doing any of the following, it is worth a diagnostic before the fault gets more expensive.

Skyrocketing utility bills with no change in usage
Furnace lights then shuts down after a few seconds
Frozen evaporator coil or ice on the refrigerant lines
Yellow or orange burner flame instead of steady blue
Short cycling — on and off every few minutes
Heating and air conditioning service built around Corunna
Cold winters and sticky summer humidity put heavy seasonal load on both the furnace and the condenser. Across the 46730 area that translates into a steady stream of failed capacitors, clogged filters, dying blower motors and refrigerant leaks — most of which we can diagnose and repair in one visit.
Local homeowners often run their system harder than the design intended, especially during June through August. That accelerates wear on contactors, capacitors and blower bearings.
Because Indiana runs gas forced-air furnaces with central air conditioning, the transition between seasons is when we see the most emergency calls — equipment that sat unused for months.

Corunna46730 HVAC questions, answered
Do you handle ductless mini-split systems?
Yes. Ductless installations have grown quickly in Indiana, 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.
Why is my furnace short cycling?
Short cycling in Corunna most often comes from a restricted airflow path — a loaded filter, a closed register, an undersized return — or from an oversized unit. It can also be a failing flame sensor or a pressure switch fault. We measure static pressure and temperature rise before concluding anything, because guessing at this one is expensive.
Do you service commercial and light commercial properties?
Yes. Around Corunna 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.
Do you charge extra for nights, weekends or holidays?
No. Our pricing in Indiana is the same at 2am on a holiday as it is at 2pm on a Tuesday. Emergency calls are dispatched the same way as scheduled calls and carry no overtime premium.
Can you give me a price over the phone?
We can give you realistic ranges — and this page lists the ones homeowners in Corunna see most often — but a firm price needs eyes on the equipment. Any company that quotes a final number without seeing the unit is usually quoting low to get through the door.
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.
