Should I replace the furnace and AC at the same time?

If both are near end of life, replacing together gives you one matched, right-sized system, one labor mobilization, and aligned warranties — often cheaper than two separate jobs. If only the furnace has failed and the AC is newer, a good installer confirms the new furnace and coil work with your existing equipment instead of upselling the pair.

Does replacing both as a system improve efficiency?

Yes, when it's done as a matched set. The furnace, indoor coil, and AC condenser are rated to work together, and a whole-system changeout is the moment to right-size with an ACCA Manual J load calculation rather than copying the old (often oversized) equipment. Ask the installer to size the whole system, not just swap boxes.

If replacing both furnace and AC, what timeline should Burlington homeowners expect for combined installs?

A combined furnace and AC replacement requires coordinated scheduling for matched equipment and proper refrigerant and airflow balances. Typical project timelines depend on permit turnaround and equipment availability. Request a project schedule that lists permit pull dates, expected delivery, and the install-day sequence to avoid mismatched equipment pairing and extended home disruption.
