Property managers send us other contractors' maintenance reports to ask whether they are good. Most are not. Here is what to look for.
Per-unit readings
Static pressure across the filter and coil, supply and return temperatures, refrigerant superheat and subcooling, compressor and fan amp draws. Numbers, with the date. Without numbers there is no trend, and without a trend nobody sees a failure coming.
Photos
Every unit, every visit. Coil condition, belt wear, rust, the economizer damper position. A photo settles arguments and shows the owner what they paid for.
A condition grade and a ranking
Each unit graded, and the roof ranked. Which three units need budget next year, and why. This is what turns a maintenance contract into a capital plan.
Repairs recommended, with prices
Not "recommend further evaluation." A part, a price, and whether it can wait.
What is not in it
Marketing. A report that recommends replacing everything is as useless as one that recommends nothing.
If your current report has two of these five, ask for the other three. If it has none, call us.
Why the bigger rooftop unit is not the safer choice
Oversized HVAC is the most common mistake on Valley roofs. It short-cycles, it leaves the building humid, and it costs more every month. Here is the math.
Do economizers actually work in Phoenix?
The most common question from facility managers, and the answer is yes, for about a third of the year, if anyone ever made them work.
VRF or rooftop units: when each one is right for a commercial building
Variable refrigerant flow gets pitched as the answer to everything. It is the right answer for some buildings. Here is how we decide.
Tell us about the building. We will come measure it.
