Questions to ask before you sign
Matt's list for this job.
- Why do you recommend replacing both systems now, and what are the alternatives?Replacing a working companion unit should come with a reason you can weigh against keeping it.
- What did the separate heating and cooling calculations show, and which equipment sizes fit those results?Heating and cooling sizing can point to different needs in the same house.
- What exact furnace, outdoor unit, indoor coil, and controls make up the proposed system?A complete equipment list gives competing contractors the same installation to price.
- What duct, return-air, filter, or zoning problems need correction for this system to work properly?Comfort depends on distributing air through the house, even after every major component is new.
- What is included for refrigerant lines, venting, condensate, gas, electrical, permits, and disposal?The piping, drains, venting, and utility connections are part of delivering a working system.
- How long will we lose heating or cooling, and who coordinates the work and any extra charges?A coordinated work sequence limits the gaps between removal, trade work, and startup.
- At handoff, can I get the startup measurements, warranty terms, and confirmation of who submits registration and incentive paperwork?Commissioning records and completed paperwork give you something concrete to review at handoff.
Also worth asking
- Can you list the exact equipment and all installation changes in the written bid?Model names leave out the labor and connection changes needed to put that equipment into service.
- What does the labor warranty cover, and what maintenance or registration is required?Parts coverage may exclude troubleshooting and return visits, and missed maintenance or registration can affect your coverage.
