Heating
Heating guides
- Heating How long does a furnace last in Michigan? A well-maintained gas furnace in West Michigan typically lasts 15–20 years. Our long heating season means furnaces here log heavy run-hours, so maintenance history is the biggest predictor of whether yours reaches the top of that range. Read guide →
- Heating Why is my furnace short cycling? Short cycling means your furnace turns on and off in quick bursts without reaching the set temperature. The most common causes are a dirty filter restricting airflow, a faulty flame sensor, an oversized furnace, or a poorly placed thermostat. Read guide →
- Heating Heat pump vs. furnace in Michigan: how to decide Both can keep a West Michigan home warm. A gas furnace delivers strong, low-cost heat in deep cold; a cold-climate heat pump heats efficiently most of the year and adds air conditioning from the same system. Many homeowners choose a dual-fuel setup that uses whichever is most efficient at a given temperature. Read guide →
Cooling
Cooling guides
- Cooling Should you repair or replace your air conditioner? Repair usually wins when the AC is under about 10 years old, maintained, and the fault is minor. Replacement makes more sense once a unit is past 12–15 years, uses phased-out R-22 refrigerant, needs a compressor, or can't keep up during a humid Michigan summer. Read guide →
- Cooling What is a ductless mini-split, and when does it make sense? A ductless mini-split is a heat pump with an outdoor unit and one or more indoor heads connected by a small refrigerant line — no ductwork. It heats and cools individual rooms efficiently, making it ideal for additions, finished basements, bonus rooms, and older West Michigan homes without ducts. Read guide →
