What Is a Furnace?

Furnaces produce hot air, which is distributed throughout the house by ductwork, a series of ducts that reach each living area and end in vents or registers.

Types of Furnace?

Gas furnaces may run on Natural Gas or Propane, as each of our brands also carries a propane conversion kit that makes conversion simple and easy to achieve. A Boiler works on the principle of heating water for steam or hot water. Some Eastern and Northern homeowners may use Oil Fueled systems as well. We concentrate on gas furnaces and electric heaters, known as Heat Pumps, as well as PTAC’s, a type of unit heater often seen in Hotels or Hospitals.

Gas Furnace

Gas furnaces are powered by either natural gas or liquid propane at varying efficiencies. The lowest available efficiency on the market is 80% AFUE (Annual Fuel Utilization Efficiency), meaning that 20% of the fuel used for heat is lost to the combustion process. The heat output is measured in BTUs (British Thermal Units) and it correlates to the size of house being heated – A 40,000 BTU furnace would be suited for a small house while a 150,000 BTU furnace would be better for a large, multi-level house. Gas furnaces are the most common type to find in any house in the US.

Clean operation, energy efficient, and totally reliable, a new generation electric home furnace provides comfort for the family and savings for the budget

What to look for when buying a furnace


BTU is the heat output of a furnace. It is recommended that a furnace has 30-60 BTUs per square foot. The larger the space, the larger the BTU needed. Please note that a home’s geographic location may affect the BTUs needed from a furnace. 

AFUE determines how efficiently a furnace converts energy into heat. The higher AFUE ratings = higher energy efficiency.

Furnaces are built with single-stage, two-stage, or modulating burners. Having a unit with more than one burner stage allows for the unit to operate at different capacities, which helps reduce energy consumption.

How Much Does It Cost to Install a Furnace In Your House?

The purchase price and costs of HVAC installation have continued to rise. The cost of installing a Furnace/ AC system in Ohio has increased each year. HVAC systems in general have become more expensive, and installation quotes can be unnerving. Our Furnace and AC systems are always priced at wholesale, and our team will arrange your furnace and AC installation too. Our expert staff at HVACDIRECT.COM typically save our customers over 5 thousand dollars on a furnace/AC & coil package! We urge you to call and get started on selecting the best HVAC at wholesale prices, at HVACDIRECT.COM HVAC.

Sizing a furnace takes into account several factors: square footage, basement (finished or unfinished), insulation and other issues. Our staff will listen to the details, ask the right questions, and take all the factors into account. Then we can show you your best options, look at costs and help you select the perfect furnace fit for your home!

Our trained staff advises hundreds of customers each week on selection of the right furnace or HVAC system for their home or project. Once you know all the facts, and examine your options, you will find it simple to make the choice that is best for you. 

Before breakdown happens is always the right time to replace a furnace, but it often takes a failure to alert homeowners to problems! Most homeowners try to replace furnaces before winter sets in. If your furnace is over 15 years old, it is a good time to have a pro take a look at it, and see what may need attention. 

Any sign of faltering or struggle to run, noise, difficulty in starting, unexpectedly high utility bills, soot in the air: all are signs of trouble, along with advanced age. Most often it is wise to replace the coil at the same time as your furnace: they are a team! 

Because we are dealing with gas or other fuels, and because the manufacturers’ warranty requires a licensed installation to be registered, it is essential to use an HVAC professional in installation. 

Installation of a furnace usually requires less than a complete days’ work to install. Naturally the removal of the old unit and any adjustments or rerouting may require several hours. 

HVACDIRECT.COM maintains a complete staff of expert technical assistants and are available to our customers online and on the phone! 

Our trained expert sales staff is ready and able to advise you on all your HVAC options, including comparing and contrasting fuel type, sizing and efficiency. They are a call or click away!

We expect our systems to run beyond warranty, normally in excess of 15 years. It is not unusual for a furnace to run well for 20 years.

Warranties vary by brand. Our brand partners offer warranties from 10 Years, to 10 Years parts & Lifetime Heat Exchanger guarantees! 

The regular changing of filters is the number one maintenance tip. Clean vents or registers is important, along with listening to your system. Keep the area around your furnace clean and clear. Finally, it Is best to schedule yearly exams after the first 5 years as well.
