HVAC Maintenance: Spring Cooling and Fall Heating Visits
Seasonal visits that check the furnace before winter and the air conditioning before summer.
Overview
HVAC Maintenance, Explained.
Heating and cooling equipment wears gradually. A flame sensor collects residue, a capacitor weakens, a condensate trap fills with sediment, a filter loads with dust. None of it is dramatic on its own, but together it reduces efficiency and comfort and eventually causes a breakdown — usually on the coldest or hottest day of the year, when the system is working hardest.
Paramount maintenance is organized around the Michigan seasons. A fall visit prepares the furnace or heat pump for winter; a spring visit prepares the air conditioning for summer. Each follows a defined checklist and records measurements, so changes from one season to the next can be compared. You receive a clear summary of what was found, what was cleaned or adjusted, and anything worth planning for. A seasonal tune-up is one of the most useful visits a homeowner can book, and it is always welcome.
The visit
HVAC Maintenance: What the Visit Involves
- 01
Fall heating visit
Burners, igniter and flame sensor are inspected and cleaned as needed. The heat exchanger is visually inspected where accessible, venting and draft are checked, safety controls are tested and temperature rise is measured.
- 02
Spring cooling visit
The outdoor coil is cleaned, capacitor and contactor tested, and refrigerant performance checked through pressure and temperature readings. The indoor coil, drain pan and condensate line are inspected and cleared where needed.
- 03
Airflow and controls
On every visit the filter is checked, the blower inspected and static pressure measured. Thermostat operation, staging and any humidifier or accessory controls are confirmed to be working as intended.

Written summary
Findings and measurements are recorded and shared with you, along with anything that needs attention now and anything simply worth watching. Recommendations are explained without pressure, so planning can happen on your timetable.
How often should my heating and cooling system be serviced?
A common approach in Michigan is twice a year: the furnace or heat pump in fall before the heating season, and the air conditioner in spring before the first warm spell. Homes with a heat pump use the same equipment year-round, which makes both visits especially worthwhile. Filters should be checked more frequently between visits, depending on the type of filter installed.
Does a newer system still need maintenance?
Yes. Even new equipment collects dust on coils and burners, condensate drains still clog and electrical components still wear. The first few seasons also establish a baseline of measurements — temperatures, pressures and static pressure — that make later changes easier to spot. Many manufacturers also expect regular maintenance, so it is worth reviewing your equipment’s documentation.
How often should I change my furnace filter?
It depends on the filter. Standard one-inch filters are commonly changed every one to three months, while deeper media filters often last longer between changes. Pets, renovation dust and continuous fan operation all shorten that interval. Checking the filter monthly at first gives you a sense of how quickly it loads in your home, and the maintenance visit confirms the right interval.
What should I check before calling about a system that will not start?
A few simple checks can help: confirm the thermostat is set to the correct mode with fresh batteries if it uses them, make sure the furnace switch and breaker are on, check that the furnace access panel is fully closed, and look at the filter. If the system still will not run, or anything seems unusual, leave further investigation to a technician.
