FAQs
How do I know it’s time to replace my unreliable HVAC system rather than repair it again?
In Sweetwater’s extreme weather—triple-digit summers and chilly winter nights—an HVAC unit that is over 12–15 years old, needs frequent repairs, or can’t keep your home within 2–3 °F of the thermostat setting is usually at the end of its economic life. If repair estimates exceed about 40 % of the cost of a new system—or if your utility bills have risen more than 20 % in the last two seasons due to reduced efficiency—replacement is the smarter long-term investment.
What size and type of replacement HVAC unit is best for Sweetwater homes?
Because Nolan County falls in Climate Zone 2, most residences need a system sized between 25 and 40 BTU per square foot. A Manual J load calculation—factoring in insulation levels, duct design, window orientation, and air infiltration—is the only accurate way to determine size. Heat-pump systems with a SEER2 rating of 15.2 + and HSPF2 of 8.1 + are ideal for our hot summers and mild winters, while gas furnaces in the 80 AFUE range remain popular if natural-gas service is available.
How long does a full HVAC replacement take and will I be without heating or cooling?
A straightforward change-out in Sweetwater typically takes one working day (6–8 hours). More complex jobs involving duct repairs or electrical upgrades can stretch to two days. We remove the old equipment, set and level the new condenser/heat-pump pad, connect the indoor air handler or furnace, pressure-test and evacuate the refrigerant lines, and commission the thermostat. Your home may be without conditioned air for 3–5 hours total; we schedule early starts so comfort is restored by mid-afternoon.
What is the average cost to replace an HVAC system in Sweetwater and what factors affect price?
Current 2024 pricing ranges from $7,200 for a 2-ton single-stage AC and gas furnace combo to $14,500 for a 5-ton variable-speed heat pump with smart zoning. Cost swings are driven by equipment efficiency (SEER2/HSPF2/AFUE), capacity, ductwork modifications, refrigerant line length, and electrical panel upgrades. Local permitting fees generally add $85–$125, and a city inspection is required before final sign-off.
Are there rebates, tax credits, or financing options available for a new HVAC unit?
Yes. Through December 31, 2032, the federal Inflation Reduction Act offers up to $2,000 in tax credits for qualifying heat pumps (SEER2 ≥ 15.2, HSPF2 ≥ 8.1) plus $600 for an advanced thermostat. On-bill financing is available from Sweetwater Utilities Board at rates as low as 6.99 % APR over 60 months. We also partner with Carrier® and Ruud® to provide seasonal rebates of $250–$1,000 on high-efficiency systems when installed by a factory-authorized contractor.
What warranties and maintenance requirements come with a replacement HVAC system?
Most manufacturers supply a 10-year limited parts warranty and a 1-year labor warranty when the product is registered within 60 days of installation. We extend labor coverage to 5 years with the purchase of our Comfort Shield maintenance plan, which includes two precision tune-ups per year, priority scheduling, and 15 % off any out-of-warranty repairs. Documented maintenance is required to keep the parts warranty valid, so we log each service visit in our digital portal for your records.
