Getting a new HVAC system installed is a big investment. Here's exactly what the process looks like from the first phone call to final commissioning — so there are no surprises.
Whether you're replacing a 20-year-old furnace and AC, upgrading to a heat pump, or installing HVAC in a new construction home, the installation process can feel overwhelming. How long does it take? What permits are needed? Will you be without heat or AC during the install? This guide walks you through every step of HVAC installation in Louisville so you know exactly what to expect.
Every HVAC installation starts with an on-site assessment. We don't quote over the phone based on square footage alone — that's how systems get improperly sized. During the assessment, we evaluate:
We perform a Manual J load calculation — the industry-standard method for determining exactly how much heating and cooling capacity your home needs. This prevents oversizing (which causes short cycling, humidity problems, and premature failure) and undersizing (which leaves you uncomfortable on the hottest and coldest days).
After the assessment, we provide a detailed written proposal with good-better-best options. Each option includes the equipment brand and model, efficiency rating, warranty details, total installed price, and estimated annual energy costs. We explain the differences honestly — we'll tell you when the upgrade is worth it and when it's not.
Louisville Metro requires mechanical permits for HVAC installations. We pull all permits and schedule inspections — you don't need to deal with any of it. Depending on equipment availability and our schedule, most installations are completed within 1–3 weeks of signing the proposal.
Most residential HVAC installations take 1 day for a straightforward replacement and 2–3 days for more complex projects (ductwork modifications, heat pump conversions, or electrical upgrades). Here's what happens:
Louisville Metro's mechanical inspector will visit to verify the installation meets code. We coordinate the inspection so you don't have to. About 2–4 weeks after installation, we follow up to make sure everything is running perfectly and answer any questions.
