FAQs
How fast can you replace my HVAC unit if I book a same-day appointment in Lake City?
Once you call before 12:00 p.m., our dispatch team can have a certified technician at your door within 2–4 hours. After an onsite evaluation and your approval of the written estimate, most standard residential system replacements are completed the same day, typically in 6–8 hours, including removal of the old unit, installation, start-up, and final inspection.
What types and brands of HVAC systems do you install or replace?
We are factory-authorized dealers for leading manufacturers such as Trane, Carrier, Lennox, Rheem, and Goodman. We install and replace central air conditioners, heat pumps, gas furnaces, dual-fuel systems, mini-split systems, and high-efficiency packaged units. Our Lake City warehouse stocks the most common tonnages (1.5-5 tons) and SEER ratings so we can deliver same-day replacements without waiting for special orders.
How do I know whether I need a full replacement instead of a repair?
During the diagnostic visit we measure system age, compressor and blower motor condition, refrigerant levels, energy consumption, and repair history. If your unit is over 10–12 years old, uses R-22 refrigerant, has a failed compressor, or the estimated repair cost exceeds 40% of the price of a new high-efficiency unit, we typically recommend replacement. We’ll provide side-by-side cost comparisons so you can make an informed choice.
Do you offer financing or rebates for new HVAC systems?
Yes. We partner with several lenders to provide 0% APR promotional financing for up to 18 months or low-interest plans stretching 5–10 years. In Lake City you may also qualify for utility rebates of $150–$600 and federal tax credits of up to $2,000 on ENERGY STAR®-rated heat pumps or furnaces. Our comfort advisor will walk you through the paperwork and apply any eligible incentives to lower your upfront cost.
Are same-day appointments available on weekends and holidays?
Absolutely. Our Lake City emergency replacement team operates 7 days a week, 365 days a year. Weekend and holiday service windows are 8 a.m.–6 p.m. Standard labor rates apply; only after-hours work (after 6 p.m.) incurs a modest premium. You’ll receive a firm, upfront price before any work begins.
Will the new HVAC unit be properly sized for my home?
Yes. We perform a Manual J load calculation that factors in square footage, insulation levels, window orientation, occupancy, and local Lake City climate data. Correct sizing prevents short-cycling, reduces energy bills, and extends equipment life. After installation, we verify airflow with static pressure tests and register balancing to ensure every room reaches the desired temperature.
