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.

In Burnsville, one furnace or AC tune-up is $129, and doing both together is $219. The visit includes cleaning, ignition and safety testing, airflow measurements, and a written rundown of anything that is wearing.
Burnsville's 1970s split-levels and split-entries have roomy utility rooms with a chimney already in place, and the common surprise is comfort rather than breakdown: lower levels run cold while upper bedrooms run warm. Our visit measures airflow and return capacity, because balancing the ducts and moving a thermostat often does more than new equipment would. On furnaces from the 1990s and early 2000s, we pay special attention to flame sensors and igniters, the parts that quit on the first sub-zero morning.
Hillside lots bring their own checks. PVC vents leaving low on the slope can be buried by sliding roof snow, and condensers on sloped side yards may have sunk or tilted. In spring we level them if we can and clean the coil, and for homes near Crystal Lake we watch for an evaporator coil that ices on muggy days.

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.
Partly. We clean the system and measure airflow, and we often find a dirty filter, a weak blower or a return that is too small. The cold lower level is usually a duct design issue, since the system was built around one thermostat and few returns. We will say what balancing, a lower return or a second sensor would involve.
Snow sliding off the roof or thrown by a snowblower can bury a vent that exits near grade, and the furnace locks out when the intake is blocked. At the tune-up we clear and inspect the pipes, check the slope and pressure switch, and flush the condensate trap. We can recommend a vent shield or relocation if the spot is a problem.
