Plans & Financing
Keeping your HVAC system running well takes more than a single repair call — it takes a plan. Lake Area Heating & Air offers both a maintenance plan and flexible financing to make that easier for Clay & Putnam County families.
Regular maintenance catches small problems in your Central AC, furnace, heat pump, or mini-split before they become expensive repairs, and it keeps your system running efficiently through Florida’s long cooling season. Lake Area Heating & Air’s maintenance plan covers both residential and commercial equipment.
Big HVAC repairs and replacements shouldn’t have to wait, which is why Lake Area Heating & Air offers financing through Wisetack. Applying is quick, and it lets Keystone Heights homeowners move forward with the system they need on a schedule that works for their budget.
Powered by Wisetack
Every new residential system comes with a 10-year parts warranty from the manufacturer.
For added protection, we now offer an optional 10-year labor warranty—giving you full coverage and long-term peace of mind. This labor warranty must be added within six months of installation, so if we installed your system within the past six months, you’re still eligible!
