FAQs
How do I know it’s time to replace my HVAC system instead of repairing it?
Most systems in Graysville last 12–15 years. Consider replacement when you see several of these signs at once: (1) frequent or expensive repairs that add up to 50 % of the cost of a new unit, (2) rising power bills caused by declining efficiency, (3) uneven temperatures or poor humidity control, (4) use of the phased-out R-22 refrigerant, and (5) loud operation or short cycling. A modern high-efficiency system can cut annual energy use by 20–40 %, so the savings often offset the cost of replacement.
What size HVAC unit do I need for my Graysville home, and how is it calculated?
Proper sizing is determined with a Manual J load calculation, not by square footage alone. Our technicians measure the home’s heated area, insulation levels, window type and orientation, local design temperatures (Graysville’s summer highs around 92 °F and winter lows near 30 °F), occupancy, and duct layout. For example, a well-insulated 1,800 ft² house may need a 3-ton (36,000 BTU) system, while an older, drafty home of the same size could require 3.5 tons. Oversizing leads to short cycling and humidity problems; undersizing shortens equipment life and causes discomfort. We provide the calculation in writing before any installation.
How much does a full HVAC replacement cost in the Graysville area?
Prices vary with capacity, efficiency, and installation complexity. Typical ranges for a complete replacement—including equipment, thermostat, labor, permit, and haul-away—are: • 14–16 SEER2 single-stage heat pump or A/C & gas furnace combo (2.5–3 ton): $7,500–$10,000 • 17–18 SEER2 two-stage/variable-speed systems: $10,000–$12,500 • 19–20 SEER2 inverter heat pumps or 95 %+ AFUE modulating furnaces: $11,500–$15,000 Duct repairs, electrical upgrades, or zoning add $500–$3,000. We provide firm, written quotes after a free on-site assessment.
How long will the replacement take, and will I be without heating or cooling?
A straightforward swap of an outdoor unit and indoor air handler/furnace typically takes one full workday (6–8 hours). If new ductwork, line-sets, or condensate drains are required, the job may extend to two or three days. During the actual change-out you’ll be without heating or cooling for 4–8 hours; we schedule work early in the day and provide temporary heaters or window units in extreme weather when necessary.
Are there rebates, tax credits, or financing options for energy-efficient HVAC systems in Graysville?
Yes. As of 2024 homeowners can claim the federal Energy Efficient Home Improvement Tax Credit (25C) for 30 % of the installed cost—up to $2,000—for qualifying heat pumps and up to $600 each for high-efficiency furnaces or A/C coils. Alabama Power offers rebates of $150–$700 for new heat pump installations, and TVA’s EnergyRight program provides low-interest loans to qualifying customers. Our company also offers 0 % APR financing for 12 months or low-interest plans up to 120 months, subject to credit approval. We complete all rebate paperwork for you.
What maintenance does my new HVAC system need to keep its warranty valid?
Manufacturers require the system to be registered (usually within 60 days of installation) and professionally serviced at least once a year—twice is better in our hot, humid climate. Homeowners should: • Replace or clean filters every 30–90 days. • Keep the outdoor unit free of leaves and debris, maintaining 2-ft clearance. • Pour a cup of vinegar in the condensate drain line each spring to prevent clogs. • Call for service if you notice unusual noises, odors, or performance drops. Our Comfort Club plan provides biannual tune-ups, priority scheduling, and documentation to preserve the 10-year parts and compressor warranty on most new systems.
