HVAC FAQ
Straight answers — no sales pitch. Local HVAC Dispatch is a free referral service, not an HVAC contractor. We connect homeowners with independent local HVAC contractors that serve their ZIP code. Local HVAC Dispatch does not warrant or guarantee any work performed. All estimates, quotes, pricing, and project scopes are provided solely by the independent contractor. It is the homeowner's responsibility to verify that each contractor possesses the necessary license and insurance required for the work being performed. All persons depicted in photos or videos are actors or models, not contractors listed on this site.
No. Local HVAC Dispatch is a free referral service. We connect you with independent, local HVAC contractors that serve your ZIP. They do the work, confirm the scope with you, and set their own prices.
It depends on the season and the contractor's schedule — during heat waves and cold snaps, everyone calls at once. Emergency no-heat and no-cool calls typically get priority. The contractor will confirm timing when they call you back.
Weigh the repair cost against the system's age, efficiency, and condition. If the repair is a large fraction of replacement cost and the system is past about two-thirds of its expected life, get a replacement comparison before authorizing the repair. A cracked furnace heat exchanger always means replacement — that's a safety issue, not a judgment call.
Typically 12–17 years for air conditioners and heat pumps, 15–20 for furnaces, and 20–30 for boilers — with regular maintenance. Neglected systems die younger; well-maintained ones often outlast the averages. The compressor or heat exchanger failing on an old system is usually the end of the line.
Whatever a Manual J load calculation says your home requires — not your square footage, and not the size of the old unit. Oversized systems short-cycle: they blast on and off, never dehumidify properly, and wear out early. Ask to see the load calculation in writing.
Often, if it's genuine: seasonal tune-ups with real measurements, priority scheduling during peak season, and a repair discount. The value is in caught-early failures and jumping the queue during a heat wave. Read what's actually included before signing — and keep records, since manufacturers often require documented maintenance for warranty coverage.
Modern cold-climate heat pumps heat effectively well below freezing — far better than older models. In very cold regions they're typically paired with backup heat (electric strips or a gas furnace in a dual-fuel setup) for the coldest stretches. Ask for performance data at your area's design temperature.
Only if they're dirty — there's no calendar schedule. Legitimate triggers are visible debris, post-renovation dust, pest evidence, or mold. Without one of those, most homes don't need it for years. Beware of unrealistic cheap specials: legitimate duct cleaning takes hours with serious professional equipment.
Equipment size and efficiency tier, ductwork condition, electrical or venting requirements, and installation complexity. An independent contractor inspects your property on-site to evaluate the specific scope for your home.
No — there's no obligation. The introduction is free. Compare the estimate with any other contractor you like before signing anything.
