Questions to ask before you sign
Matt's list for this job.
- How did you determine the cooling size for my house?Oversizing can shorten cooling cycles and hurt humidity control, so capacity needs a reason behind it.
- Which outdoor unit and indoor coil are included, and are they an approved match?The indoor coil and outdoor unit have to work as a compatible combination.
- Will you reuse the refrigerant lines, and how will you confirm their condition and compatibility?Reaching the new unit does not establish that old refrigerant lines are suitable for reuse.
- Could the existing airflow or drainage be contributing to the problem, and what have you checked?Poor airflow and drainage trouble can follow you straight into the replacement system.
- Does this quote account for the pad, electrical work, disconnect, permits, and hauling away the old equipment?A new pad or electrical correction is easier to budget when it appears in the original quote.
- How will you leak-test, evacuate, and verify the refrigerant charge during startup?Leak testing, evacuation, and charge verification help establish that the refrigerant circuit was properly prepared.
- What are the labor and equipment warranties, and who completes registration and available rebate paperwork?Registration is easy to overlook, and equipment coverage may still leave you paying service labor.
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.
