How much should Naperville homeowners expect to check on contractors before booking?
- Can I replace my gas furnace with a heat pump?
- Yes — a heat pump both heats and cools, so it can fully replace a gas furnace. In colder areas a dual-fuel setup keeps the furnace as backup for the coldest days. Either way, insist on a Manual J load calculation; conversions can need duct resizing or an electrical upgrade.
- When is replacing an old heat pump better than repairing it?
- If it's past 12–15 years, still uses phased-out R-410A refrigerant, needs a compressor, or the repair bill approaches a third of replacement cost, replacing usually wins. A reputable contractor compares both paths before recommending.
- What key checks should I request during a heat pump replacement estimate in Naperville?
- Ask the estimator for a load calculation, duct and airflow inspection, and refrigerant-line evaluation. Confirm they will provide a written equipment recommendation and warranty details. Request a timeline that accounts for permitting and seasonal availability in Naperville.
- How important is a Manual J load calculation for Naperville homes?
- Very important. A Manual J determines correct system sizing for Naperville's hot summers and cold winters. Request a copy of the calculation and ensure the contractor uses it to size equipment and design ductwork or distribution upgrades.
