What a Maintenance Visit Includes

Most maintenance visits in this industry are a filter change and a sticker. That's not maintenance, it's a sales call with a screwdriver. A real visit produces numbers: electrical readings on the motors and capacitors, temperature split across the coil, static pressure across the system, refrigerant readings checked against the nameplate, and combustion readings on a gas furnace.

Numbers matter because they trend. A capacitor that has dropped below its rated tolerance is on its way out, and it usually goes on the hottest or coldest day of the year. Caught early it gets replaced on your schedule instead of in an emergency. Property Renovators Home Services has been maintaining equipment across Montgomery County for 10 years, with 20 years of trade experience behind the standard, and you get what we measured in writing.

What This Covers

  • Capacitor readings compared against the rated value, so a weak one gets caught before it strands you
  • Contactor inspection for pitting and burnt points
  • Amp draw on the compressor and both motors, compared against nameplate values
  • Temperature split measured across the indoor coil
  • Static pressure readings, which reveal duct and filter restriction most inspections never look for
  • Refrigerant pressures, with subcooling checked against the nameplate and superheat against the charging chart
  • Condensate drain flushing and float switch testing
  • Coil condition inspection, indoor and outdoor, with cleaning where it's needed
  • On gas equipment: burner condition, flame sensor, venting, and heat exchanger inspection
  • A written record of every reading, so next year's numbers mean something

When Maintenance Is Worth Scheduling

  • The system hasn't been looked at in more than a year
  • You just bought the home and have no history on the equipment
  • Energy bills have been climbing without a change in how you use the system
  • The system is keeping up but it runs noticeably longer than it used to
  • You want to know honestly how much life is left before planning a replacement
  • Before summer for cooling, and before winter for heating, not during the first hot or cold week

How a Maintenance Visit Runs

We take readings before we clean anything

Cleaning first hides the condition the system was in. The readings come first so the record reflects reality.

We tell you what is drifting, not just what is broken

Parts rarely fail without warning. A capacitor at the bottom of its tolerance is the single most useful thing a maintenance visit can find.

We separate what needs doing from what can wait

You get a clear split between what should be handled now and what to keep an eye on. Nothing gets done without your approval and a written quote first.

You keep the numbers

The readings are written down and left with you. That record is what makes the next visit meaningful, and it's yours whether or not we come back.

Frequently Asked Questions

Cooling before summer and heating before winter is the standard, so twice a year on a system that does both. A single well done visit a year is still far better than none, and we'll tell you which your system needs.
It's worth it when the visit produces readings. If nobody hands you numbers, you paid for a filter change. Our visits produce a written record of what was measured, and that's the whole point.
It helps, mostly by catching restriction and electrical drift before they damage something expensive. It doesn't make a worn compressor new. What it reliably does is remove surprises and let you plan.
Yes, all seven days, 8am to 7pm. Call (301) 395-3831.
It's the resistance the blower is working against, and it's the vital sign almost nobody measures. High static means restricted ducts or a restrictive filter, and it quietly shortens the life of the blower motor and the compressor while making the system underperform.
Yes. Most of the equipment we maintain was installed by someone else. We're interested in the condition it's in now.

"Jacob is the best ever. He made my dream come true by installing my catwalk for my cat to the ceiling when no other contractor could handle the job. I was extremely impressed by his expertise and he is definitely someone you can trust. It's hard to come by professionals who are also kind and Jacob is just stellar. I even paid him extra because he did such an amazing job."
