HVAC Help for Southern Indiana Homeowners
Straight answers about heating and cooling, written for Clark and Floyd County homes. No sales pitch — just how the equipment works and how to tell a small fix from a big one.
From the field — Justin Henry, Henry Brothers · Updated July 28, 2026
Henry Brothers started out as ductless mini split specialists, but the questions we get around Clark and Floyd County go well past mini splits. Your central AC quits on the first muggy afternoon. The furnace won't light on a cold morning. Something's short cycling and you can't tell if it's a forty-dollar part or a four-thousand-dollar problem.
So we're putting the answers here. These guides are written for homeowners, not contractors — plain language, no pressure. How heating and cooling actually work, what the common failures look like, and when it's worth picking up the phone. Read one and never call us, and that still counts as a good day.
Everything here is grounded in Southern Indiana weather — the Ohio Valley humidity that leans on a coil all summer, and the freeze-thaw winters that are hard on a heat pump. That's the equipment we see, in the houses we see it in.
Where a guide quotes a number, we point at where it came from. The federal ENERGY STAR heating and cooling program publishes the maintenance and replacement guidance most of these pages lean on, and the AHRI Directory of Certified Product Performance is where you can look up any specific model's independently tested efficiency rating instead of taking a brochure's word for it.
None of it is gated. When a guide runs out of road — gauges on a system, a meter on a capacitor — that is the point where it is worth a call, and you should know what that costs before you make it. We diagnose before we quote and hand you the number in writing, and the number we quote is the number you pay; the Transparent Pricebook™ explains why we publish prices at all. A Clean and Check℠ tune-up runs $99, and the Two Seasons Membership books both seasonal visits for the year and adds 10% off every repair.

Which one fits an Ohio Valley winter, how they make heat differently, and what each costs to run month to month.
Read the guide → UpkeepHVAC Maintenance Checklist
The seasonal upkeep that keeps a system going — filters, coils, condensate drains — and what is worth leaving to a tech.
Read the guide → LifespanHow Long HVAC Lasts
Typical lifespans for central AC, furnaces, and heat pumps, plus how to tell whether yours is worth fixing or near the end.
Read the guide →The Companion Glossary
Every guide leans on a few technical terms — refrigerant, a heat pump, short cycling. When one of them trips you up, the HVAC Dictionary breaks it down in a single plain paragraph, no jargon left standing.

Most of these guides cover standard central systems — furnaces, central AC, heat pumps — because that's what runs in most Southern Indiana homes. Mini splits are what we know best, but we also diagnose, repair, and give second opinions on regular residential HVAC. Same approach either way: find what's actually wrong, then give you a number before any work.
If another company already handed you a quote that doesn't sit right, a second opinion is the place to start. We'd rather fix a twenty-year-old unit that can still be fixed than sell you a system you don't need.
