How long does a heating installation take?

Most installations are done in one day, but it can stretch to two if there are complications like ductwork modifications or electrical upgrades. The crew will give you a time estimate after they see the existing setup and the new equipment.

How do I know if I need a new heating system?

If your system is over 15 years old, needs frequent repairs, or your energy bills keep climbing, it may be time. Also, if it makes unusual noises, cycles on and off too often, or leaves cold spots, a replacement could be more cost-effective than another repair.

What happens if the weather is bad on installation day?

We work in most conditions, but heavy rain or extreme cold can affect the job, especially if we need to work outdoors for a heat pump or venting. We'll keep you informed and reschedule if conditions are unsafe for you or our crew.

Will you leave any mess behind?

No. We lay down drop cloths, protect your floors, and vacuum up dust and debris. We also haul away the old unit and all packaging materials. You should be able to walk through your house after we leave without seeing any trace of the work.

How does the estimate work?

We come to your home, look at the existing system, measure the space, and talk about your comfort needs. Then we give you a written, itemized quote that lists the equipment, labor, and any extra work like duct sealing or electrical upgrades. There's no obligation to proceed.

What should I do before the crew arrives?

Clear a path to the heating equipment and remove anything stored around it. Move furniture or rugs out of the work area if possible. Secure pets in another room. Also, make sure the thermostat is accessible and that we can reach the main power or gas shutoff if needed.

The work

About our heating installation

When a homeowner calls about heating installation, they are usually facing a system that is old, unreliable, or too expensive to run. The unit may have failed mid-winter, or they are planning ahead before the cold weather arrives. They need a new furnace, heat pump, or boiler that fits their home and budget, and they want the job done right the first time.

Our crew starts by removing the old unit, shutting off gas or power, and disconnecting the lines. We inspect the ductwork, venting, and electrical panel to make sure everything is compatible with the new system. Then we set the new equipment, connect the fuel and power lines, seal the duct connections, and run the system through its paces, checking gas pressure, airflow, and thermostat calibration.

Every installation is different because of the home's layout, the age of the existing system, and the condition of the ductwork. A tight attic or a cramped closet makes the work slower. Replacing a boiler with a heat pump may require new lines or a different electrical circuit. If the ductwork is undersized or leaky, it has to be repaired or modified, and that adds time and cost.

On the day of the install, we lay down drop cloths, protect floors and walls, and keep the work area as clean as possible. We haul away the old equipment and packing materials. Before we leave, we run a full test and walk you through the new thermostat. You should clear a path to the equipment and make sure pets are secured. Afterward, change filters regularly and keep the area clear.

A new heating system is a major purchase, and the difference between a good and a poor installation shows up in comfort, energy bills, and how often the system needs repairs. Proper sizing, correct venting, and sealed duct connections are what make the heat even and the system quiet. A careful installer checks the heat exchanger, verifies the flame, and confirms the blower speed matches the home's needs.

When you get quotes, ask what is included in the price—equipment, labor, permit fees, and disposal of the old unit. Compare efficiency ratings and what they mean for your monthly bills. Ask about the warranty on parts and labor, and get it in writing. A detailed, itemized estimate helps you see where the money goes and makes it easier to compare bids fairly.

Load Calculation

A proper heat load calculation, not just square footage, determines the right size. Oversized units short-cycle and waste energy; undersized ones run constantly and never get the house warm.

Flue Gas Testing

For gas and oil systems, checking the flue gas for carbon monoxide and draft ensures safe combustion. Improper venting can backdraft and cause a serious hazard inside the home.

How the job runs

Our 4-step heating installation process

Assess and Size

We measure your home, check insulation, window efficiency, and existing ductwork. Then we calculate the correct heating capacity so the new system matches your home's actual heat loss.

Remove Old Unit

We shut off power and fuel, disconnect the lines, and carefully take out the old furnace, boiler, or heat pump. We haul it away and dispose of it according to local rules.

Install New System

We set the new equipment, connect fuel and electrical lines, seal the ductwork or piping, and mount the thermostat. We make sure everything is level, secure, and meets code.

Test and Demonstrate

We run the system through heating cycles, check gas pressure, airflow, and safety controls. Then we show you how to set the thermostat and what to listen for, and answer any questions.
