HVAC Maintenance

Maintenance for Your Home System.

The best time to find a problem is before the first hot week or the first cold snap, not during it. A tune-up tells you where your AC, heat pump, ductless system or gas or propane furnace really stands. We check it over, show you what we found, and tell you what needs doing now and what can wait. Call or text to set it up.

What a Maintenance Visit Includes

We maintain home AC, air-source heat pumps, ductless systems and gas or propane furnaces. We check the electrical side, airflow, filters, coils and drains. On gas and propane furnaces we also check the combustion side. Your oil provider still handles all oil-furnace service.

We write down the readings so the next visit has something to compare against. A tune-up can catch something starting to go, but no one can promise a part will never fail. We tell you what we found and keep repairs separate from the routine checks.

What This Covers

  • We test the capacitor and contactor, the parts that start and run the motors, and flag any that are wearing out
  • Electrical current readings for the compressor and both motors, checked against equipment ratings
  • Air temperature checks before and after it passes through the indoor unit
  • Airflow or static-pressure checks where appropriate to the equipment and symptoms
  • Refrigerant performance checks when indicated and permitted by the operating conditions
  • Accessible condensate drain and float-switch checks; any cleaning or repair is defined in the agreed scope
  • Accessible indoor and outdoor coil checks; any cleaning is defined in the agreed scope
  • On natural-gas or propane furnaces: burner, flame sensor, venting and heat-exchanger checks appropriate to the equipment
  • A written record of completed checks and any limits on the assessment

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 a clearer view of equipment condition before planning future work
  • 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

We inspect the initial condition and perform appropriate checks before and after maintenance. The order depends on safe operation and the manufacturer instructions.

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

We explain any measurement outside the equipment requirements and what it may mean. A part can fail without an earlier warning, so an inspection is a snapshot rather than a guarantee.

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.

We explain the findings

We explain the completed checks, any concerns and what remains uncertain. Any additional diagnosis or repair needs a separate agreed scope.

Frequently Asked Questions

Follow the manufacturer's maintenance schedule and account for the equipment, use and conditions. We can discuss a suitable plan after assessing the system.
No. Our maintenance is for residential AC, air-source heat pumps, ductless systems and natural-gas or propane furnaces. Your oil provider handles oil-furnace service; commercial, geothermal and VRF equipment are outside our scope.
No. Refrigerant should not be added as a routine maintenance step without an equipment-specific reason and assessment.
We record the limitation and explain any follow-up needed. An unperformed test is not reported as passed.
It helps assess the resistance to airflow through the system. It must be interpreted with the equipment requirements and other checks; it does not identify every cause by itself.
No. It can identify some developing concerns and support proper operation, but it cannot guarantee equipment life or predict every failure.
We serve homeowners in Germantown, Gaithersburg and Montgomery Village. Call or text with the full service address and the work you need so we can confirm the request.
A quick professional check once a year, heating before winter and cooling before summer, catches the small things before they turn into a cold night with no heat. Change a standard filter every one to three months, sooner if you have pets. It is the cheapest thing you can do to make a system last.
Watch for energy bills creeping up with no change in use, rooms that will not stay even, strange noises or smells, short cycling on and off, and repairs that are starting to stack up. None of those mean you have to replace it today, but they are worth a look so it does not quit on the hottest or coldest day. We will tell you honestly where yours stands.

"Jay and Jacob were amazing getting my HVAC system operating correctly. Other companies probably would've said I need a new system but they took the time to diagnose the issues, addresses them, and went above and beyond getting the system in tip-top shape. They easily put 40 hours into the project to get it in order working well into the evenings and nights to ensure the home is comfortable. They will be my go-to for home services moving forward."
