Best MERV Rating for Allergies in a Minnesota Home
MERV 8, 11, 13 or 16? What each rating catches, why filter depth matters as much as the number, and how to upgrade without choking your furnace or AC.

An Anoka tune-up is $129 for one furnace or one AC, or $219 for the pair on a single visit. We clean, test and measure, and report plainly.
Anoka's oldest houses near downtown and the Rum River are boiler and gravity-conversion country, so a fall visit here often looks different from a suburban one. On a hot-water boiler we check system pressure, the expansion tank, the relief valve and the circulator, and we bleed trapped air from upstairs radiators that stay cold. Converted gravity furnaces get a close look at the heat exchanger and the old chimney connection, because plaster walls and tall ceilings keep these systems running hard through a cold snap.
Spring work centers on the condenser. Cottonwoods along the Rum and the Mississippi mat the coil with fluff in June, so we wash it and check the clearances. Many older houses cool upstairs rooms with ductless heads, and those get their filters, coils and drain lines cleaned. Away from downtown, the postwar ramblers need the standard furnace and condenser checklist.

Each $129 visit covers cleaning, a safety and carbon monoxide check and a written report. Boilers, heat pumps and mini-splits fall in our $129–$349 maintenance range, confirmed when you book.
A tune-up record is not one of the listed items. Anoka Municipal Utility's central AC rebate asks for the AHRI certificate for the matched system and a dated invoice with make, model and serial number, so keep those from the install. Confirm the current form with the utility before you buy.
We test system pressure, the expansion tank's air charge, the relief valve and the circulator, check the venting, and look for leaks at fittings and radiator valves. Air bled from cold upstairs radiators is part of the visit. Boiler pricing falls in our $129–$349 maintenance range and we confirm the number when you call 612-429-3465.
