 A furnace is a permanently installed appliance that provides heat to an interior space through fluid movement, which could be air, hot water, or steam. For modern combustion furnaces, the most common fuel source is natural gas. Other common fuel sources include coal, wood, propane or fuel oil. in other cases, in places where the electricity costs are low, electric resistance heating is used as a source of heat. Traditionally, combustion furnaces, which always need to be vented outside, expels heat along with the exhaust through a flue.

 Lets go over the different types of units.

  1. A central warm-air furnace is a type of space-heating equipment in which a central combustor or resistance unit provides warm air that circulates through ducts leading to the various rooms. This type of furnace generally uses natural gas, fuel oil or electricity.
  2. A forced-air furnace uses a fan to force the air through the ducts
  3. A gravity furnace circulates the air by gravity and relies on the natural flow of warm air rising up through ducts while cold air falls through ducts that return to the furnace to be reheated.
Home heating systems generally consist of three parts.
  1. The controls and safety devices including a
  • gas valve
  • ignition control
  • igniter
  • heat sensor
  • transformer
  • limit control
  • blower control board and
  • flame rollout switch

A heat sensor, also known as a thermostat, measures the temperature and determines when the temperature needs to be raised in your home. When the air temperature drops, the thermostat signals the blower and the heater to turn on.

  1. Once the blower and the heater turn on. the combustion in the heater creates heat, while the blower creates a negative pressure on the intake side and moves air over the heat exchanger, raising the temperature and distributing it throughout the house by the heating ducts. Cooler room air is returned to the furnace through return ducts where it is warmed. The warm-air-out, cool-air-in-cycle continues until the desired temperature is reached and the thermostat signals the furnace to shut down.
  1. The burner is where the flame originates and is drawn into the heat exchanger by the negative pressure produced by the draft inducer. The hot gases produced by the combustion of the flame pass through the chambers of the heat exchanger. The cooled gases then enter the draft inducer blower and are pushed into the venting pipes and the exhaust gasses are then directed out of the house through the vent pipes.

We also offer energy-efficient boilers to help you save money on your monthly utility bills and have technicians that have the expertise required to accurately assess the state of your equipment and make recommendations to suit your needs.

Most homes are heated with a furnace or a boiler. Boilers are a natural gas, oil, propane or solid fuel burning appliance that produces hot water or steam.  This water is circulated through pipes to heat radiating tubes throughout the home. Most homes are heated with a furnace or a boiler.

Boilers provide either hot water or steam.  Steam is distributed through pipes to steam radiators.  Hot water can be disbursed through a baseboard system or through pipes for in floor heating.

Steam boilers operate at a higher temperature than hot water boilers and are less efficient. High efficiency boilers are offered for homeowners today and may qualify for energy rebates.

Boilers that are old and inefficient should be replaced.  They are costing you money.  Replacement boilers will save you energy and costs on repair bills. Old boilers may be over or under sized which can cost you money.

How a Heat Pump Works – ACE HI PLUMBING, HEATING & AIR

How a Heat Pump Works


  • Using electricity as its energy source, heat pumps are used for either the heating or cooling of your home by transferring heat between two reservoirs.
  • In the warmer months, the heat pump acts like an air conditioner, removing heat from the air inside your home and transferring it outside
  • During colder months, heat from outdoor air is extracted and transferred to the interior of you home. Believe it or not, even a 32° Fahrenheit day produces enough heat to warm a home via a heat pump.


  • Year-round, energy-efficient indoor comfort for moderate climates – A central heat pump helps maintain comfortable temperatures inside your home and reduces humidity levels year-round. Homes located in regions with severely cold temperatures may either require supplemental heating or be better served with an air conditioner/furnace combination.
  • Cleaner air – As your heat pump system draws air out of various rooms in the house through the return air ducts, the air is pulled through an air filter, which removes airborne particles such as dust and lint. Sophisticated filters may remove microscopic pollutants as well. The filtered air is then routed to air supply duct work that carries it back to rooms. Whenever the air conditioner is running, this cycle repeats continually, constantly filtering and cleaning the air in your home.
  • Quieter operation – Because the compressor bearing unit of the typical central heat pump system is located outside the home, the indoor noise level from its operation is much lower that that of a free-standing air conditioning unit.

The Dangers of Gas Furnace Flame Roll Out – ACE HI PLUMBING, HEATING & AIR

What is Furnace Flame Roll Out

Gas furnaces are among the safest appliances any home can have. However, it is recommended that all furnaces have routine maintenance and repairs done. Parts that do not move still degrade from corrosion and soot damage which can lead to burners and exchangers to develop a very dangerous flame roll out condition.

A gas furnace works by mixing air and natural gas traveling through a burner that heats up a metal heat exchanger. The combustion chamber is separate from the heat exchanger that gets forced air blown over it, and is heated by the heat exchanger and then exits through the heat ducts.

The burners of the gas furnace are located at the bottom of the heat exchanger. All the parts of the gas furnace from the burners to the heat exchanger are made of metal. Over the years, corrosion and soot products start to interfere in the travel of hot gases from the flames up and out of the flue. Flames that were once confined to the immediate area of the burner spread out as a flame roll out when the air and gas exchange is impeded.

Damaged Heat Exchanger

Forced air units create air pressure outside of the heat exchanger that is greater than the pressure on the inside of the unit where the combustion process occurs. Even the smallest of holes and cracks can cause an eddy, which is a rotational movement of gases disrupting the flow of byproducts and has the same effect as restrictions in a heat exchanger passage, causing a flame rollout. Heat exchangers with cracks or hoes that have rusted through also cause flame roll out which increases the danger of carbon monoxide gas to enter into the home. CO is deadly in small concentrations, and it is also odorless and tasteless so it cannot be detected by a person’s natural senses when present.

Signs of Flame Roll Out

Flame roll out is a serious and potentially deadly safety concern. There may not be any exterior indication of a problem in the early changes but can usually be seen on some furnaces as  a discoloration of the exterior painted surfaces around the combustion chamber.

Why Furnace Flame Roll Out is Dangerous

Any gas combustion that is not properly confined to the appropriate area could obviously have consequences.  This condition is serious and requires immediate attention because it can cause damage to the insulation on electrical wiring, gas valves, and combustible materials nearby. Many surfaces have a flame roll out switch that cuts off gas to the burners when flame roll out is detected through temperature sensors. However, there have been many instances of the safety switch being circumvented by homeowners and even repair personnel.

Regular furnace maintenance is recommended to help prevent furnace flame rollout. A professional heating technician will check for malfunctions, giving you the peace of mind knowing your furnace is operating safely and efficiently all winter long.

The Fundamentals of Carbon Monoxide- ACE HI PLUMBING, HEATING, & AIR

Safe and efficient combustion in a furnace requires a proper air-to-gas ratio. This is dependent on the availability of air(combustion inlet) and the ability to discharge oxygen-depleted air (flue gas venting). There is a potential for incomplete combustion whenever there is a malfunction of either the inlet or outlet system. This can result in carbon monoxide (CO) gases.

Residential gas heating systems with non-dedicated combustion air inlets are inside the living space without direct communication to the outside air. Many of the older homes have furnaces that draw air from the occupies space. As the air is pulled from the space, it is replenished by air infiltrating the house through the window, doors, and other obvious opening. This can create a potentially dangerous situation.

Modification done to a structure can inadvertently inhibit this flow of combustion air, causing the furnace or any other gas appliance to malfunction. Other problems in the house can turn an improperly vented furnace into a CO-generating machine.


Most residential furnaces use natural draft to drive the combustion process. Even 80%-AFUE furnaces with combustion blowers are natural-draft furnaces.The combustion blower assists the combustion gases, but the flue still operates like a natural-draft furnace. The natural pressure differential created by heating the combustion gases in the furnace is what pushes the flue gases up and out of the flue.

Combustion gases expand as they are heated which makes them less dense than the colder air entering the furnace, so they weigh less. They also exist at a lower pressure than that of the colder inlet air.

Since the combustion gases are at a lower pressure, the higher-pressure inlet gases displace them, pushing them up and out of the flue. The inlet air must always be at a higher pressure than the combustion gases so that this pressure differential can be maintained in order for the flue to operate properly. Air stops drafting through the furnace when this pressure differential is diminished by the flue pressure becoming too positive or the combustion air inlet becoming too negative. This is when CO is created and if the furnace is not drafting, the CO ends up staying in the residence.

The pressure differential needed to drive the flue gases up and out of the furnace is somewhere between 1 and 5 Pascals depending on the outdoor temperature. This means as the flue gases leave the furnace, they must be at -1 to -5 Pascals relative to atmospheric pressure. The pressure differential needed to be maintained between the inlet and outlet of the furnace’s combustion air inlet system is very delicate and can be easily disturbed. Anything that will raise the pressure in the flue or lower the pressure in the combustion air inlet system can interrupt the flow of air through the furnace and create carbon monoxide.


To make sure your home and family get through this coming winter both safe and sound, you should take the time to do your own home safety audit. Follow these steps to perform your winter safety audit.


Start with the obvious and have a professional inspect and service your furnace. Everyone is going to be spending more time indoors during the winter. You should make sure that your furnace is working properly, the pilot light and the thermostat are both working properly and the filter is clean. You should also make sure that there are no leaks or openings in your supply lines or furnace ducts.

Experts recommend changing regular furnace filters once a month during the heating season and changing high-efficiency filters at least every three months. Make sure to get a supply of filters that fit your unit. Having clean furnace filters is extremely important. A blocked furnace filter can cause the “limit switch” on your furnace to activate, turning it off and leaving you without heat until the switch is replaced by a professional.

Be sure to remove any flammable items from around your furnace including paints, paint thinners, and paper products. If you have a fireplace, be sure to have the chimney cleaned to get rid of any creosote buildup and eliminate the possibility of chimney fire.


Seal any openings in your walls including the tiny ones and move any piles of wood or firewood away from your foundation. A mouse can get through a 1/4-inch opening. This will keep the mice and voles out of your home. These animals are not dangerous but could be carrying diseases. No one wants to share their home with dirty rodents.

People need handrails and solid steps in icy conditions so be sure your steps and handrails are sound. Repair them now while the weather is still warm. Doing so can prevent accidents from happening this winter


Shut off the water supply to your outside taps and drain the supply lines as it gets colder in the fall. Doing so guarantees that there will be no water left in the pipes to freeze and burst them.


Be sure to have fresh batteries for your Carbon Monoxide and smoke detectors if you have these installed in your home. If you do not have these installed, now is the time to do so. They are easy to install and inexpensive. Most importantly, they could save a life. Also, be sure to have your fire extinguisher checked. Consider buying a new one if the extinguisher is more than 10 years old.


Prepare your emergency kit. You will need candle and a lighter or matches, a flashlight and batteries, a portable radio, blankets, and warm clothes for everyone. Be sure to stock bottled water and nonperishable foods for your family and pets, a first aid kit, And finally, be sure to have a camp cooking stove in order to have warm meals even if it’s only canned soup.
