Westfield's seasonal swings — hot, humid summers and cold winters — demand HVAC systems that perform, and contractors who understand the local climate. Whether you're running central AC on a July afternoon, cranking the furnace through January mornings, or considering a modern heat pump, we're your trusted local partner. We work on all major brands, from Armstrong Air to LG and Climate Master, and we pride ourselves on transparent service and upfront answers.
Across Westfield and the rest of Hamilton County we handle AC repair, AC installation, furnace repair, furnace installation, and the annual maintenance plan that keeps both running.

One contractor for repair, installation, maintenance, and air quality — across every system in your home.
Central AC repair, installation, and routine maintenance keep your home cool and comfortable. We diagnose AC problems accurately, replace aging units with efficient modern systems, and schedule regular tune-ups to prevent summer breakdowns. We work on all brands and equipment types.
Furnace repair and geothermal installation deliver warmth through Westfield's cold winters. We diagnose heating failures quickly, install efficient replacement systems, and keep equipment running with fall maintenance. If your system is aging or inefficient, we'll explain the upgrade path.
Modern ductless and central heat pumps offer efficient heating and cooling year-round. We install mini-splits for room-by-room comfort, repair heat pump systems when they fail, and maintain them to keep efficiency high. Heat pumps are ideal for Westfield's mixed seasons.
Cleaner, healthier air at home starts with the right upgrades. We install whole-home air filtration systems, UV light cleaning, and humidity control solutions. Many homeowners add these services when replacing furnaces or AC units — we can also upgrade existing systems.
From your first call to ongoing support, here's what working with Harmon looks like.
Call us at (317) 588-8303 or use our contact form to describe your comfort need — repair, installation, or maintenance. We'll schedule a time that works for you and dispatch our team with the right tools and parts.
Our technician arrives, inspects your equipment, tests it thoroughly, and explains what we find in plain language. For repairs, we diagnose the problem and discuss options. For new installations, we evaluate your home's layout, ductwork, insulation, and climate control needs to size the system correctly.
We present your repair or installation options with pricing, warranty terms, and timeline. No surprise charges. If you choose a new system, we discuss brands, efficiency ratings, financing, and how routine maintenance keeps your investment protected.
Our team completes the work to full manufacturer specifications. We test every connection, calibrate controls, and walk you through operation and routine care. For replacements, we remove and recycle the old equipment properly.
After service, you have a partner for maintenance tune-ups, warranty claims, and any questions about your system. Our maintenance plan members get both annual inspections on schedule.
Our maintenance plan covers a full heating inspection and a full cooling inspection each year for just $170. Plan members get consistent equipment care, faster response times, and problems caught early — before they become expensive repairs.
A new HVAC system is a real investment, and Harmon Heating & Cooling works with Service Finance to help make that investment manageable. Whether you're replacing an aging furnace before winter or upgrading to a more efficient central AC system, financing options are available so an unexpected repair or planned upgrade doesn't have to wait.
Our team can walk you through financing options through Service Finance at the time of your estimate, so you know what to expect before any work begins.
