The Temprasure Service Agreement: HVAC Maintenance Plans in Ypsilanti and Southeast Michigan

A service agreement is only worth having if the maintenance behind it is real. Plenty of HVAC companies in Southeast Michigan sell memberships that amount to a sticker on the furnace and a technician who spends twenty minutes looking for something to quote. The Temprasure Service Agreement is built on the same tune-ups we do for anyone: a fall furnace visit with a combustion analyzer, a manometer and a carbon monoxide check at the registers, and a spring air conditioning visit with the condenser coil cleaned, the capacitor tested against its rating and the refrigerant charge verified by superheat and subcooling. Each visit ends with a written report of the readings. The agreement simply makes sure both visits happen every year without you remembering to call.

Here is what it includes, in full. Two tune-ups a year: the furnace in the fall, before DTE gas starts flowing hard, and the air conditioner in the spring, once it is warm enough to run the system under load. Priority scheduling when something fails, which in practice means an agreement customer with no heat in January or no cooling in July goes ahead of routine calls on the board. A discount on any repair during the year, applied to the flat-rate price before you approve it. And reminder scheduling: we track when your visits are due and reach out to set them, so the furnace gets looked at in October instead of after it quits in December. That is the whole plan. There is one agreement, not three tiers with names, and nothing in it is designed to get you into a replacement conversation.

The reason it matters in this climate is that equipment here goes from idle to full load twice a year. A furnace that has sat since April is asked to run every night from November to March, through 6,000-plus heating degree days and at least one polar vortex stretch most years. An air conditioner that has sat since September gets its first real test on the first humid week of June. The parts that fail, the flame sensor coated over the summer, the capacitor that lost a few microfarads over the winter, the condensate drain that grew algae, are exactly the ones a seasonal tune-up catches. Most of the emergency calls we run in Washtenaw and western Wayne County are on systems that nobody has opened in years, and most of them would have been a line item on a tune-up report months earlier.

The agreement also builds a history. After a few years we know your equipment: the age of the heat exchanger, the trend in the capacitor readings, whether the AC has needed a top-off, which means it has a leak. That record is what lets us tell you honestly when a repair is worth it and when the system is on borrowed time, and it is what a buyer's inspector wants to see when you sell the house. It also keeps the manufacturer's warranty valid, since most require documented annual service for a parts claim.

We will not push the agreement on anyone. A single tune-up is available to any homeowner at a flat price, and some people prefer to book each one themselves. The agreement is for people who would rather have it handled and want to be first on the schedule when it matters.
