Why is my furnace making a loud banging noise?
A loud bang when your gas furnace starts is often delayed ignition: gas builds up before it lights, then lights all at…
Old furnace, rising bills or repairs that keep adding up? We replace furnaces with the right size and efficiency for your home, with a free in-home estimate and a written price.
Available in: Winchester & Wilmington, and Norfolk from January 2027

Heating and cooling service from our Norfolk branch starts January 1, 2027. Until then, our Norfolk team is here for plumbing, drains, boilers, gas lines, septic and wells. Call the Norfolk office with any questions.
When the repairs keep coming and the bills keep climbing, a new furnace usually pays you back.
Furnace installation covers removing the old unit, setting the new furnace, connecting the gas, venting, ductwork and thermostat, and testing everything before we leave. Your technician sizes it for your home, rather than just copying what was there.
New furnaces are more efficient than the ones they replace, so the running costs drop as well. You get good, better and best options in plain English, a free in-home estimate and financing on jobs of $500 or more.
Every install is done to code and to the manufacturer's specifications by trained, licensed technicians, with a 1-year warranty on the installation and the manufacturer's equipment warranty on top.
The right system depends on your fuel, your climate and what's already in the house.
A natural gas or propane furnace gives quick, hot air on the coldest nights. A good fit where gas is already in the house.
One system for summer and winter, moving heat instead of burning fuel. Very efficient in mild winters.
A heat pump handles most of the year, and the furnace takes over in deep cold. Popular in Winchester winters.
The same steps on every visit, so you always know what's next.
We look at the home, the ductwork and the old system, and ask how you use it.
Good, better and best, with running costs explained in plain English.
A written price, signed before any work starts. Financing on jobs of $500 or more.
Old equipment out, new system in, connected and tested. Floors protected.
We check airflow and temperatures, set the thermostat and show you how it works.
Photos and warranty details come with your invoice.
Free in-home estimate, then a written price you sign before we start.
Your technician explains what each option costs to buy and to run.

A new furnace in the same spot, connected, vented and tested.
Usually the lowest upfront cost.

More of the fuel you pay for becomes heat, with quieter, more even comfort.
Often paired with a new thermostat.
Your technician will explain the differences in efficiency, warranty and price, and recommend what suits your home rather than what's on the truck.
We'll help you choose. Here's the short version of what changes from one furnace to the next.
Lower upfront cost. About 20 cents of every heating dollar goes up the flue.
Costs more to buy and install, but burns less gas every winter, so it can pay for itself over time.
Simple and lower cost, but louder, with bigger temperature swings between cycles.
Runs gently on low and ramps up only on the coldest days: quieter, more even heat and fewer cold spots.
Natural gas or propane, and the model on your written quote.
The share of your fuel that becomes heat in your home. About 80% is standard; 95% and up is high efficiency.
Where this furnace sits against similar models. Further right means less fuel wasted up the flue.

We stayed late finishing an install, because we were not going to leave the customer without heat overnight.Brandon, HVAC apprentice, Winchester

Cost, lifespan and timing.
It depends on the size of the home, the efficiency you choose and any venting, gas line or ductwork changes. In-home estimates are free, and you get a written price before any work starts. Financing is available on jobs of $500 or more.
It varies a lot with maintenance, filter changes and how hard it works. Rather than going by age alone, compare the cost of the next repair with the cost of a new furnace, and factor in the lower running costs of a newer, more efficient model.
Most straight replacements are done in a day. Changing fuel, venting or ductwork can add time, and your technician will tell you the schedule with the estimate.
It's a job for a licensed technician. It involves gas piping, venting, electrical connections and combustion safety, and mistakes can be dangerous. Manufacturers also expect professional installation to honor their warranties.
Every new system is installed to code and to the manufacturer's specifications by trained, licensed technicians, and the installation is covered for one year. Manufacturer equipment warranties pass through to you, and some brands extend their parts warranty when the equipment is registered.
Yes. Financing is available through Wisetack on jobs of $500 or more, and AC and heat pump replacements are among the jobs our customers finance most. You can check your options from home in a couple of minutes. All financing is subject to credit approval.
