Question 4

How often should I service my HVAC system in Hayfield's climate?

Accepted Answer

Rochester's southeastern Minnesota location gives it a full continental climate — cold winters averaging 12°F lows and warm, humid summers reaching 83°F.

Heating systems run hard November through March, while 62% summer humidity creates real cooling loads from June through August.

Many Hayfield contractors offer annual maintenance plans that bundle both visits at a discount.
