Maintenance Agreements
Silver, Gold and Platinum memberships, each with biannual seasonal tuneups, priority scheduling and discounted pricing on parts and labor.
What goes wrong in a system nobody looks at
Air conditioners in this part of Texas run for most of the year, and heat pumps run all of it. A system that works nine months out of twelve gets very little attention, so the problems that end it are the quiet ones. A condenser coil clogs with cottonwood fluff and yard dust and the compressor runs hotter every week. A run capacitor weakens a little each summer until the morning it does not start the fan. A condensate drain grows a film of algae and then a plug, and the first anyone hears of it is water on the ceiling or a float switch shutting the system off.
Heating has its own list. Burners collect scale, a flame sensor gets a coat of residue and starts shutting the furnace down after a few seconds, and a heat exchanger can crack without ever announcing it. None of these cost much to catch while they are small. All of them cost far more when they arrive on the coldest night of January or the hottest afternoon of August, when every other house on the street is calling the same shops.
That is the case for looking at the equipment on a schedule instead of waiting for it to fail. It is cheaper to find a weak capacitor in April than to replace a burned-out compressor in July.

How the seasonal tuneup works, and how the plans are set up
Douglas Mechanical sells maintenance agreements as three memberships named Silver, Gold and Platinum. Every one of them includes biannual seasonal tuneups: one visit before the cooling season and one before the heating season. The published benefits of membership are correction of problems and issues found along the way, longer equipment lifespan, scheduled service reminders, maintenance documentation, priority scheduling, and discounted pricing on parts and labor.
What a seasonal tuneup looks at is ordinary trade craft. On the cooling side that means the outdoor coil, the condensate drain, the run capacitor and contactor, the fan and compressor amp draw, and the refrigerant pressures read against the day's conditions. On the heating side it means the burners and the heat exchanger on a gas furnace, the flame sensor, the blower, and the safety switches. The exact checklist for your system depends on what is installed, so ask the office what a visit covers on your equipment.
The written plan page does not spell out what separates Silver from Gold from Platinum, and this page will not guess. For that, call the office at (281) 299-0949. It is open Monday to Friday 8am-6pm, Saturday 8am-5pm and Sunday 11am-5pm. Technicians themselves are in the field 8am-8pm, seven days.
What a customer chose, and what the paper trail is for
One Google reviewer, Karen Davis, wrote about picking a plan after her new system went in: "I chose the gold plan since my system is only 9 months old, and besides tune-ups it covers the service call, no matter how many times a year I need them to come out." That is her experience of her plan, in her words. Coverage on your own agreement is whatever your contract says, so read it before you sign.
The maintenance documentation matters more than it sounds. A dated record of every visit, what was measured and what was replaced, shows how the system has been treated for as long as you own it. When a part is questioned under a warranty, or when the house is sold, that history answers the question without anybody having to remember. Scheduled service reminders do the other half of the job: the visit gets booked before the season instead of after the first breakdown.
Priority scheduling and discounted pricing on parts and labor are what members get when something does fail between visits. The company has been doing this work since 1975, owner Jared still prices jobs himself, and nobody on staff works on commission, so a plan is explained rather than pushed. If you are not sure a plan fits the age and condition of your equipment, a free in-home estimate is the place to ask.
