What a Furnace Installation Includes

A furnace you cannot trust wears on you. You listen for it kicking on, you wonder if this is the winter it quits, and some rooms stay cold no matter where you set the thermostat. A new gas or propane furnace, sized to your home, takes that off your mind and brings back steady heat you can stop thinking about.

A quick scope note: we install and service natural-gas and propane furnaces. Oil furnaces are outside what we do. And no-heat does not always mean you need a new furnace. We look at the equipment and what is actually wrong first, and we tell you straight whether a repair or a replacement is the better call for your home. Any safety problem we find, you hear about right away.

What This Covers

  • A look at your current furnace and the replacement options that fit the home, before you agree to anything
  • The existing venting checked so the new furnace is vented the way it needs to be
  • Enough fresh air reaching the space the furnace sits in, so it burns cleanly and safely
  • The gas or propane supply and the connection to it checked as part of the approved work
  • Condensate drainage sorted out for a high-efficiency furnace that makes water when it runs
  • The new furnace tied into your existing ducts. We do not build new ducts or run new duct lines
  • Airflow set for the furnace and checked so the heat coming off it stays in the right range
  • Permit and inspection requirements, and who handles each step, spelled out in the written scope
  • The furnace started up and checked as conditions allow, with what we found explained to you
  • A walkthrough of the system, the thermostat, the filter, and where the shutoffs are

When a Furnace Should Be Replaced

  • A cracked heat exchanger, which is a safety issue that needs a close look before you run the furnace again
  • One part after another failing in the same winter, with the repairs starting to add up
  • Rust or corrosion showing through the cabinet and around the burners
  • An old furnace now facing a big repair that may not be worth putting money into
  • Some rooms warm and others cold no matter what you set the thermostat to
  • A furnace that was too big for the home and has short cycled on and off its whole life

How a Furnace Installation Runs

Safety and a look at the home first

If we find anything unsafe with how the furnace burns, you hear it right away, plainly, before any talk about new equipment or scheduling. We also look at how the current system heats the home.

Go over the furnace we recommend

We explain the furnace we think suits your home and why, along with the venting and the connections. The written scope lays out the equipment and the work in plain language.

Full written scope before we start

The scope names the furnace, the connections, the venting, where the water a high-efficiency furnace makes drains to, and any permits. If something comes up outside that scope, we talk it through with you before it goes ahead.

Start it up, check it, and walk you through it

We start the new furnace, check that it runs right as conditions allow, and show you the thermostat, the filter and the shutoffs before we go.

Frequently Asked Questions

It means the equipment needs a qualified safety assessment. The appropriate repair or replacement depends on the damage, parts, manufacturer requirements and applicable coverage.
Often yes, as long as your furnace, coil and airflow all work together. We check that they match before we tell you to keep it.
The proposal should identify the furnace model, compatible settings, venting, connection work and any installation limits before you approve it.
The installation plan identifies applicable permit and inspection requirements before work is approved.
Bigger is not better here. A furnace that is too large blasts on and shuts off fast, which leaves rooms uneven. The size needs to suit the home and the ductwork you already have.
Leave for fresh air and call 911 from outside. Stay out until emergency responders give permission to return; do not investigate the furnace.
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.
Bigger is not better. An oversized system short-cycles, leaves rooms uneven, and wears out early. The right size comes from your home, not a rule of thumb, so we measure instead of guessing. You end up with a system that is quiet, even, and matched to your house.
It comes down to three things: how old the system is, what the repair costs against the value of the whole unit, and how well it has been keeping up. Once a system is past its teens and the repairs start stacking, replacement usually makes more sense. We look at yours and tell you straight which way we would go if it were our own home, with no pressure either way. Call or text 301-355-2238 and we will walk through it.

"Jay & his team are my goto for HVAC problems. Weather it's a small repair like replacing a capacitor or larger project like full system replacement. Jay and his team @ Mora Heating & Air do quality work at an affordable price but add top rated customer service that many large companies just can't & don't give."
