Mercer Island98040 HVAC questions, answered
What does a new system cost in Mercer Island?
A complete residential replacement in the 98040 area generally lands between $6,000 and $13,000 installed, depending on capacity, efficiency rating and how much ductwork has to be modified. We always perform a Manual J load calculation first, because an oversized unit costs more to buy and runs worse than a correctly sized one.
Is my system low on refrigerant, or is it leaking?
Refrigerant does not get "used up" the way fuel does. If your charge is low, there is a leak somewhere — usually at a flare connection, a schrader core or the evaporator coil. We locate and repair the leak rather than simply topping up the charge, because a top-up alone will fail again.
Do you handle ductless mini-split systems?
Yes. Ductless installations have grown quickly in Washington, particularly in older homes without existing ductwork. We service indoor heads, clean filters and drain lines, check line-set insulation and diagnose communication faults between heads and the outdoor unit.
What brands do you service in Mercer Island?
All of them. Our 98040 technicians are trained on Trane, Lennox, American Standard, Carrier and essentially every other residential brand sold in Washington, including discontinued lines. We keep a broad parts catalogue on the trucks for exactly that reason.
Why is my system short cycling?
Short cycling in Mercer Island most often comes from a restricted airflow path — a loaded filter, a closed register, an undersized return — or from an oversized unit. It can also be a failing flame sensor or a pressure switch fault. We measure static pressure and temperature rise before concluding anything, because guessing at this one is expensive.
Is my carbon monoxide risk something I should worry about?
With any combustion appliance, yes. A cracked heat exchanger can spill carbon monoxide into the living space, and it is odourless. We perform combustion analysis and a CO test on every furnace and boiler call in Mercer Island, and we recommend a working CO alarm on every level of the home regardless of who services your equipment.
