HVAC Maintenance Agreements: Running Them So Every Visit Happens

Maintenance agreements bring HVAC businesses their steadiest revenue and are the easiest work to let slip. This covers structuring them, scheduling the visits and proving the work at renewal.

An HVAC maintenance agreement is a promise. You service the customer's units on a schedule, and in return they get fewer breakdowns, priority when something does fail, and usually a better price on repairs. For the business it is the steadiest revenue there is. It is also the easiest to let slip, because a missed agreement visit costs nothing today, and the customer only notices at renewal.

What a good agreement covers

Which units: every indoor and outdoor unit by location, model and serial number, so nobody argues later about what was included.
How often: typically twice a year, before the cooling and heating seasons, or quarterly for commercial sites and heavy use.
What each visit includes, as a written checklist rather than "general service".
What happens on a breakdown: response priority, and whether repairs are discounted.
The term, and what happens at the end of it.

Getting the timing right

For most residential agreements, pre-season servicing is the whole point. A unit serviced in April is far less likely to fail in June. So agreement visits have to be scheduled around the season instead of squeezed in when the calendar allows, and they bunch up, with hundreds of units wanting a visit in the same six weeks.

Plan for that:

Create the visits weeks ahead so dispatch can spread them across the available days.
Route them by area, so a technician does four agreement visits in one neighbourhood instead of crossing the city between each.
Protect them from the first heatwave. Once emergency calls start, agreement visits get pushed back, so decide in advance how many slots a day stay reserved for them.

The agreement visit

Every technician should use the same checklist, so the customer gets the same service whoever turns up:

Clean or replace filters
Clean the evaporator and condenser coils
Clear and flush the condensate drain
Check refrigerant pressures and record the readings
Check electrical connections, capacitors and contactors; measure amp draw
Check the thermostat and controls
Test run and record supply and return air temperatures
Photograph each unit before and after
Note anything that needs a repair quote

Turning findings into work

Agreement visits are where you find the capacitor about to fail and the drain starting to block. Each finding should become a quote or a job before the technician leaves the area, and those findings make up most of the repair revenue an agreement brings in.

Renewal

At renewal, the customer wants to know whether it was worth it. The record answers that: every visit on time, with the checklist completed, photos, readings and what was fixed. Customers who can see that renew. Customers who can't remember the last visit don't.

What to measure

Agreement visits completed within their window, as a percentage.
Breakdowns on units under agreement, compared with units that are not.
Renewal rate.
Repair work generated from agreement visits.

In Movtro

In Movtro, agreements run as recurring jobs. For each customer you set the units, the checklist, the technician and the schedule (twice a year on fixed dates, for example), along with the agreement's end date. Each visit is created ahead of time so dispatch can plan it, either as one job per unit or one job covering every unit at the site. Visits not done by their due date are flagged as overdue, and the recurring job shows every visit it has created.

Movtro Recurring jobs on a phone with an HVAC firm's quarterly AC service and annual boiler service agreements, one with an overdue visit.

Each unit is an asset with its model, serial number and warranty, and every agreement visit adds to its service history. Technicians complete the checklist, note readings, add photos and log parts on their phone, and customers can follow their jobs in the portal. Movtro does not handle agreement pricing, invoicing or renewals.
