Furnace installation and replacement for ducted homes
If your home is heated through ducts and vents, a new furnace is only as good as the system around it. Furnace installation means looking at the ductwork, the thermostat and any air conditioning that shares the same air handler.
Tell us what's been going wrong, whether that's noisy operation, rooms that never warm up or a string of recent repairs. Thinking about a heat pump alongside the furnace? Mention it early so the equipment and controls are planned together.
Furnace replacement and your ductwork
01 · Ducts and airflow
A new furnace can't fix ducts that are undersized, leaky or missing a return. We look at airflow room by room, so the furnace replacement solves the cold rooms instead of just heating the same air faster.
02 · Furnace and central air together
If your air conditioner shares the furnace's blower and ducts, the two have to work as a pair. Replacing both? Our HVAC system installation page covers planning heating and cooling together.
Furnace installation in older homes
Older houses can bring access, venting and layout challenges, so we talk about them up front. Thinking about a heat pump alongside the furnace? It can take over most of the heating, with the furnace as backup on the coldest nights.
Fuel changes, electrical work, venting, removal of the old furnace and repairs to the house are spelled out in the proposal. You'll know what Noble Air handles and what needs another trade.
Heat with radiators or radiant floors?
If your home heats with hot water instead of ducts, a boiler is the right fit, not a furnace. See our radiant heat and boiler installation page, including our radiant heating project in Milton.
Discuss My Furnace ReplacementSigns it may be time to replace your furnace
There's no fixed age when a furnace has to go. These are the signs that usually start the conversation.
- 01
Repairs keep piling up
One repair isn't a reason to replace. A string of service calls on an aging furnace often is, especially when the next repair is a major part.
- 02
Rooms that never warm up
Cold bedrooms and uneven floors can come from the furnace, the ducts or both. A replacement is the right time to look at the whole picture.
- 03
Running longer than it used to
A furnace that runs constantly, short-cycles or makes new noises is working harder than it should. Age and airflow problems are common causes.
- 04
Thinking about a heat pump
Some homeowners replace the furnace with a heat pump, or keep a furnace as backup. Our heat pump page covers how that works.
Furnace installation questions
Should I repair or replace my heating system?
It depends on what's wrong, the age and condition of the equipment, its repair history and your goals. If you're not sure yet, start with heating repair and get a diagnosis first.
Can I keep my existing ductwork?
Often, if it's in good shape and sized for the house. We check the ducts during the estimate and tell you what should change, if anything.
Do you install every fuel type?
Send us your current equipment and what you're hoping to install, and we'll confirm what we can take on.
What will the proposal include?
The equipment, the installation work and who's responsible for what. Removal, venting, controls and any work by other trades are listed too.
