HVAC Installation FAQs
Important details to know before you replace an aging HVAC system.
How do you choose the right size HVAC system for my home?
We do a full load calculation that accounts for square footage, insulation, window exposure, duct performance, and occupancy. Correct sizing is the foundation of comfort and efficiency.
How long does a full HVAC installation usually take?
Most standard replacement projects are completed in one to two days. Projects that include major duct modifications, electrical upgrades, or difficult access can take longer.
Can I keep my existing ductwork with a new system?
Sometimes yes, but we inspect duct condition, leakage, and static pressure first. If ducts are undersized or damaged, targeted upgrades are recommended to protect system performance.
Do you install ductless mini-split systems?
Yes. We install single-zone and multi-zone mini-split systems for homes, additions, converted garages, and offices where duct installation is not practical.
Do new HVAC systems come with warranties?
Yes. Manufacturer parts warranties and workmanship coverage apply based on system type and registration requirements. We explain warranty terms clearly before installation starts.
