Questions to ask before you sign
Matt's list for this job.
- How did you calculate the needs of each room, and which spaces will each indoor unit actually serve?A head in the hallway may leave a closed bedroom uncomfortable. Each room needs a realistic coverage plan.
- What output will each zone get when the other zones are running, including in cold weather?With several zones calling, the outdoor unit has to divide its available capacity among them.
- Where will the indoor units go, and can you show me the airflow direction and service clearance?The head's location determines where air blows and whether a technician can reach it later.
- Where will the refrigerant lines and wall penetrations go, and how will they be covered and sealed?Visible piping and wall holes are permanent details. Review the route while there is still a choice.
- How will each indoor unit drain, and will any condensate pumps need maintenance or access?Condensate pumps add a service item, and inaccessible drains make a water problem harder to fix.
- Where will the outdoor unit sit, and are electrical work, permits, and any backup heating plan included?Snow, defrost water, operating sound, and electrical access can all influence the outdoor location.
- Before handoff, what leak tests and startup checks will each zone receive, and will you review cleaning and warranty responsibilities with me?Testing each zone catches problems that a quick check of the outdoor unit can miss; cleaning instructions help keep it working.
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.

How wide is the range in Seattle?
The middle half of mini-split permits in Seattle runs from $5,020 to $14,950, and a tenth of permits sit below $3,090 while a tenth sit above $21,320. A quote outside the middle half is not wrong on its own, but it should come with a reason you can see in the scope, so compare it line by line.
Have Seattle permit values changed by year?
