Furnace Service and Installation

Your family relies on your furnace to stay warm and comfortable all winter long, and a high-quality furnace can do that while also lowering your utility bills and energy costs. Due to their high efficiencies, versatility, and reasonable installation costs, furnaces remain one of the most popular choices in residential heating. They offer great flexibility to fit almost any home, acting as the core of your central air system. Contact us to learn more about our selection of high-performing heating systems for your home.

How It Works

A furnace can use propane, natural gas, heating oil or electricity to internally heat the air before it enters your living areas. Typically, they are placed in the basement, attic, crawl spaces or closet within a home and are connected to a ductwork distribution system.

Gas Furnaces

Gas furnaces are by far the most common choice of homeowners. In this system, air is drawn through returns from the distribution system and into the unit, passing over a heat exchanger that is warmed by a burner. Propane and heating oil are most often stored on-site, either inside or outside of the home in a liquified state. Natural gas is delivered from a supplier at a remote location and brought into the home through a series of underground piping.

Oil Furnaces

Due to higher costs for oil, this option has become less popular among homeowners. Oil heat requires a special burner to regulate the flow of oil into the furnace. An oil furnace is equipped to handle a specific flame style, similar to a blow torch, making it more expensive and less efficiency with operating efficiency at or below 85%.

Electric Furnaces

In an electric furnace, the air is heated by wire coils. Since it loses no heat through a chimney or vent, it is 100% efficient. Electric heat is expensive, however, so while no energy is being wasted, it will cost more than gas heat in the long run.

Why Choose Furnace Heat?

Great Efficiency

While the initial investment in a furnace can be expensive, it’s possible to save up to 30% on utility costs once it’s up and running. In addition to better functionality, you’ll significantly reduce your future energy consumption and save even more on future maintenance.

Enhanced Level of Operation

There are Single-Stage, Two-Stage and Modulating Variable Speed furnaces which provide various speeds and heat outputs. While Single-Stage can only be turned on and off, Two-Stage offers an additional half-speed for more control over your home’s temperature. Modulating furnaces can adjust heating output down to each minute, only working as much as you need it to. They also provide the best air quality since its fan can continually circulate air through your home even when the heat isn’t running.

Better Level of Performance

Offering various speed motors and advanced gas valves, furnaces offer better airflow to provide quick and consistent heat from room to room. Newer infiltration systems remove dust, mold and other impurities as it heats your home, so your family can breathe healthier while also enjoying very little to no operating noise from your system.

Longer Lifespan

With a built-in system that removes moisture from inside, and an economical on-and-off cycling system, furnaces are designed to self-protect against damaging elements. They’re also built to withstand any chemical build up overtime. Plus, furnaces are widely available, so if you do need a replacement part, they’re easy to find.

Considerations for Your Home

Size Matters

Some homeowners falsely believe the larger the furnace, the more it will heat their home. Oversized furnaces will cause spotty, uncomfortable heat and will expend extra energy warming up only to shut down before a full cycle is complete. On the other hand, furnaces that are too small will be overworked trying to heat your home which can cause it to shut down completely.

Know Your Ductwork

A high-performing furnace can only function as well as the ductwork it uses. It’s a good idea to have an HVAC professional check your ductwork for any leaks or ruptures that allows heated air to escape into areas like attics or closets that don’t need to be heated. Damaged ductwork could be affecting the efficiency of your furnace, so before you assume you need a whole new system, be sure to check your ductwork first!


What is the average lifespan of a furnace?

A furnace will typically last between 15-20 years with proper maintenance. Many factors will determine this, however, like the type of furnace or how severe the weather has been.

When is the best time to replace my furnace?

Don’t wait until an emergency to replace your furnace. If you do, you’ll likely be rushed to restore the heat and not carefully weigh the best product or service options for your home. It’s also much more difficult to coordinate with an installer on short notice. With annual maintenance checks, you should be able to catch any red flags to help you decide when it’s time to consider a new furnace.

How much does a furnace installation cost?

Typically, a furnace installation will take about one day, utilizing a 2-person team. The labor fees make up about half of the overall installation price, while the furnace’s brand, upgraded features, location and HVAC contractor all play a role in the final number as well. The national range for a furnace installation is $2,500- $6,000 based on those factors. The cost of the furnace itself will vary as well based on the various sizes and features available. On average, quality units will start around $3,000. Keep in mind these are just general estimates – contact us to schedule an appointment where we will assess your home and give you a better estimate for the cost of a furnace for your home.

What size furnace do I need?

The furnace size your home will need largely depends on the square footage of the area it will be heating and the climate in which you live. The U.S. Department of Energy breaks down the country into 7 zones, each requiring a different number of BTUs (British Thermal Units; one BTU is the amount of energy required to heat or cool 1 pound of water by 1-degree Fahrenheit). There are a number of other important criteria to consider as well, such as the age and condition of your home, so contact us for a further analysis of the right furnace size for your needs.

What type of furnace service maintenance is required?

Furnaces require regular maintenance to ensure efficiency and longevity, but there are a number of things you can do in between visits from your HVAC professional.

  • Replace the filter every other month
  • Keep grass, leaves and debris a few feet away from outdoor units
  • Keep vent and registers in home unblocked
  • Inspect flame burners to make sure they’re blue

Our HVAC Specialists will schedule an inspection appointment every year. This checkup will help promote system efficiency and prevent the need for major repairs down the road.
