Energy-Efficient Heating and Cooling in One System
A central heat pump is one of the most efficient ways to heat and cool your home year-round. Unlike furnaces that burn fuel, heat pumps transfer thermal energy from the air and use it for heating or cooling — delivering 2–3 times the heating output per dollar of energy spent. Harmon Heating & Cooling installs LG, Armstrong Air, and other premium heat pumps with expert sizing, professional installation, and full system testing.
Central heat pumps work with your existing ductwork, making installation straightforward in homes with central air. They heat efficiently even in Indiana's coldest months and cool reliably in summer. Heat pump sizing depends on your home's square footage, insulation, ductwork condition, climate, and your heating/cooling goals. Our consultation evaluates your specific situation and recommends the right system and efficiency level for your needs.

Five steps from your first in-home assessment to a fully tested system we've walked you through before we leave.
We visit your home to understand your heating and cooling needs. We measure square footage, evaluate insulation and ductwork, review your utility bills, and discuss your comfort goals. This data informs the right heat pump selection and sizing — a comprehensive in-home energy assessment, measurement of heated and cooled areas, ductwork evaluation, and a review of current heating/cooling costs.
Based on our assessment, we recommend heat pump units at different efficiency levels. We explain SEER (cooling efficiency) and HSPF (heating efficiency) ratings, payback timelines, and warranty options. You get a detailed quote with all costs — equipment, removal, installation, electrical, testing, and startup — plus financing options through Service Finance.
We handle permitting with local authorities and coordinate scheduling. We confirm electrical access, review ductwork plans, and prepare your site. A few days before installation, we confirm all details and answer any questions.
Our licensed technicians remove your old equipment carefully, install the new heat pump indoors, connect refrigerant lines, run electrical, integrate with your ductwork and thermostat, and perform all necessary tests. Professional installation to manufacturer specifications ensures efficiency and reliability. Installation typically takes one full day.
Before we finish, we run your heat pump under full load in both heating and cooling to verify output, air distribution, and thermostat response. We walk you through system operation, seasonal adjustments, filter changes, and maintenance. You receive warranty documentation and a direct number to call with any questions.
Your new heat pump is a long-term investment in comfort and savings. Protect it with our maintenance plan — annual filter changes, coil cleaning, and full system testing keep it running efficiently and extend its lifespan.
