Which Heat Pump Installation questions Lafayette homeowners ask most — and short, city-specific answers
- 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.
- Do Lafayette installers need a business license and bonding to perform heat pump replacements?
- Yes. Lafayette requires a business license and bonding for contractors working on heat pump replacements. Homeowners should ask to see a current business license and proof of bonding before signing a contract. Request written confirmation on the estimate and keep copies with permit paperwork when a city permit is required.
- How should homeowners verify licensing, bonding, and warranty promises on written estimates?
- Start with a direct check: request the contractor's license number, bonding paperwork, and insurance certificate on the estimate. Look for clear warranty language and repair-response timeframes. If warranty terms seem vague, ask for a written addendum that states warranty length, covered components, and any owner maintenance requirements.
- How do I find a heat pump replacement specialist in Lafayette?
- Look for installers who list load-calculation credentials such as NATE or manufacturer-designation, and who provide a written Manual J and equipment recommendation. Check review counts for recent replacement work and ask for local references. Request a breakdown of equipment, labor, and permit responsibilities before committing.
