Gas Furnaces


The average life of a furnace is 15-20 years. The average furnace older than 10 years is only operating at 50% efficiency. New furnaces on the market today reach between 80%-98% efficiency, offering immediate cost savings on your heating bill.

Many midwest homeowners unnecessarily pay higher energy costs and increase their stress levels by waiting until their old, inefficient furnaces give out on the coldest night of the year. The savvy homeowner, on the other hand, currently has every incentive to be proactive in reducing their energy costs and securing their family’s comfort and safety, by investing in a reliable, energy-efficient furnace today.

With all the applicable rebates offered through your local utility company and the various manufacturers, it is a great time to upgrade your energy efficiency, safety, and comfort right away! Call today, we have the experts to help you in the best, most economical way for your needs!

How to Choose a Gas Furnace?



  • Size - Size your system properly by insisting that contractors calculate the peak-hour heat loss for your home, or the amount of energy needed to replace the heat lost by your home at the coldest hour of the day. Do not rely on a "rule of thumb," which usually results in an oversized and more expensive system. The system should supply from 125 to 150 percent of your peak-hour heat loss; any larger will create reduced efficiency and other problems.
  • Efficiency - The efficiency of a gas furnace is indicated by its annual fuel utilization efficiency or AFUE rating. An 80% AFUE (today’s minimum required efficiency) means that a furnace utilizes 80% of the BTU (or BTUH) in the gas to heat your home and the remaining 20% goes up your chimney. A 98% AFUE means that a furnace utilizes 98% of the BTU (or BTUH) in the gas to heat your home and the remaining 2% vents out your chimney. The more efficient the furnace the lower the heating bill and this means less gas WASTED!
  • Venting - a TMI specialist will look at your current venting system and tell you if any changes are needed to accommodate your new furnace. This will include installing a proper "combustion air" or "fresh air intake."
  • Cost - Choose the most efficient furnace you can afford based on the system's AFUE (annual fuel-utilization efficiency) rating. It may be more expensive initially, but it will more than pay for the difference in the long run. Some state and local municipalities, as well as some utilities, offer tax credits or rebates when you trade up to a more fuel efficient system.
  • Contractor - Buy your gas furnace from a reputable company like TMI. Purchasing even a top-of-the-line furnace means nothing if the company makes mistakes during installation.
  • Warranty - Most furnace and AC's come with a basic manufacturer warranty. The warranty is divided into two categories: PARTS & LABOR. The Length of time for the coverage of each depends on the system that you purchase and the contractor you choose. Our comfort specialist will design a warranty based on your needs and wants.

Gravity Furnace Removal and Replacement


Gravity furnaces have been gradually replaced by high-efficiency furnaces. Gravity furnaces or Octopus furnaces date back to the late 1800's and early 1900's. The large, round furnaces were designed to burn coal. Even though a gravity furnace can burn natural gas, it was not designed for high efficiency. TMI has replaced over 200 gravity furnaces over the years. We have the skills and experience to make your retrofit seamless, any time of year.

5 Reasons Why You Should Replace Your Gravity or Octopus Furnace


  • To save money on monthly fuel costs! All existing gravity furnaces operate at less than 50% efficiency, sending your hard-earned dollars right up the chimney.
  • All gravity furnaces contain asbestos! Most of these out-of-date units contain unsafe fire retardants. Removing these potentially hazardous materials from your home will contribute to a healthier environment for you and your family.
  • Central air is not available! It is impossible to have whole-house central air conditioning installed with your old gravity furnace.
  • You cannot filter or humidify air with a gravity furnace.
  • Increase the value of your home! Updating to modern heating and cooling equipment increases the value and salability of your home

Heat Pumps


A heat pump is an air conditioner that contains a valve that lets it switch between cooling and heating. When the valve is switched one way the heat pump acts as an air conditioner. When it is switched the other way, it reverses the flow of refrigerant and acts like a heater. Heat Pumps can be efficient in the use of energy because it uses less to complete this task. The most common type of heat pump is the air source heat pump, which transfers heat between your house and the outside air.

A heat pump is actually an air conditioner in reverse. Imagine that you took an air conditioner and flipped it around so that the hot coils were on the interior of your home and the cold coils were on the exterior of your home. Then you would have a heater that works extremely well using electricity. Rather than burning fuel, what it is doing is moving heat.

Air Duct Cleaning


Most people are now aware that indoor air pollution is an issue of growing concern and increased visibility. If you decide to have your heating and cooling system cleaned, TMI will make sure to clean all components of the system to insure that the system is not recontaminated by lack of proper cleaning.

Duct cleaning generally refers to the cleaning of various heating and cooling system components of forced air systems, including the supply and return air ducts and registers, grilles and diffusers, heat exchangers heating and cooling coils, condensate drain pans (drip pans), fan motor and fan housing, and the air handling unit housing.

If not properly installed, maintained, and operated, these components may become contaminated with particles of dust, pollen or other debris. If moisture is present, the potential for microbiological growth (e.g., mold) is increased and spores from such growth may be released into the home's living space. Some of these contaminants may cause allergic reactions or other symptoms in people if they are exposed to them. TMI will find and seal and air duct leaks that you may have. Sealing duct air leaks can help save energy on heating and cooling bills.

A boiler is the heating plant used to create hot water or steam for hydronic baseboard, radiant heat or steam radiator heating systems. Boilers can use a variety of fuels including natural gas, propane, oil or electricity.

Steam boilers are more complex than hot water boilers and have special gauge glass, pressure gauges, blow off valves and automatic feeds.

Hot water boilers can be small, compact, energy efficient and low maintenance.

Gas Boiler - Gas boilers tend to be very reliable and very rarely experience problems.

Electric Boiler - Electric home heating boilers are amongst the most efficient around and are generally slimmer in design.

Oil Boiler - Oil home heating boilers are extremely efficient. They do not rely on conventional power and so are not affected by power outages and that makes them extremely reliable.

High Efficiency Condensing Boiler - This home heating boiler has a life expectancy of fifteen years, which is slightly longer than some of the other options available to you. It uses a larger heating exchanger and so recycles as much lost heat as it can. As a result, it may significantly reduce your heating bills and emits less CO2 into the atmosphere.

Geo Thermal


How Geothermal Works

Basically, geothermal heating/cooling systems operate via sub-surface conductive heat transfer, using the naturally renewable temperature of the earth's crust as a heat source in the winter, and as a heat sink in the summer.

Cooling Mode Operation

In the cooling mode, the hot refrigerant compressor is sent directly into the approximate 50 to 60 degree F range deep earth, which now absorbs and takes the heat away. The cooled refrigerant fluid is then circulated through the air handler where it absorbs and removes unwanted heat from the interior air. The heated refrigerant travels to the system's compressor unit where the process is repeated. Thus, in the cooling mode, the ground removes your heat for free.

Heating Mode Operation

In the heating mode, approximate 50 to 60 degree F range naturally occurring heat from deep within the earth travels to, and is absorbed by, a much colder refrigerant fluid that is circulated within the copper tubing inside a deep well/borehole. Such naturally occurring heat is transported by the refrigerant fluid to the system's compressor where the fluid is compressed, thereby raising its pressure and temperature, transforming the 55 degree F temperature into a temperature well over 100 degrees F. The hot refrigerant is then circulated through the finned tubing within an air handler, where the cold return interior air absorbs the heat. The heated air is supplied, via a fan, to the interior air space. With the heat now removed from the refrigerant fluid, it becomes very cold and is re-circulated into the ground to absorb more naturally occurring and renewable heat. Thus, the ground supplies your heat for free.

An eco-friendly alternative to pipe replacement saves Home Owners Association time and money.

      SAN DIEGO, CA, June 26, 2009 – The largest epoxy pipe lining project involving domestic drinking water systems in Southern California was completed in only 15 months by Nu Flow.
      Over five hundred condominiums were completely relined while residents stayed in their homes with little disruption. The lining technology used permanently stops pinhole leaks and prevents lead from leaching into drinking water, a common problem many residents faced. Homeowners no longer worry about leaks, floods, or consuming contaminated water since the completion of the epoxy pipe lining.
      Epoxy pipe lining is a non-invasive process that uses an epoxy barrier coating to line the inside walls of pipes. The lining restores pipes in host piping systems such as water, gas, petroleum and electrical service lines. This process can be used to restore pipes consisting of metal, iron, steel, plastic, concrete and fiberglass.
      “Pinholes are so tiny that water leaks often go undetected for months or years,” advises Cameron Manners, Nu Flow CEO. “Frequently, a leak is discovered only after some event such as a flood or diagnosis of illness caused by mold exposure in the home. The longer a pipe leaks, the more damage water can do to a structures walls, ceilings, floors, and electrical and mechanical systems.” Water treatment has escalated the leak problem and now homeowners are forced to consider pipe
replacement in as few as 10 years from when a pipe system is put in place. Pipe lining is a costefficient and eco-friendly alternative to pipe replacement that is available to consumers.

About Nu Flow

Nu Flow manufactures, distributes and installs innovative green technologies for the restoration of drinking water pipes, sewer drain and sanitary lines, lead service piping, HVAC, mechanical systems such as chiller and heating lines, fire suppression systems and pool lines and offers multiple water filtration products from a single source. Pipe rehabilitation applications domestically and internationally include commercial and domestic multi-story structures, industrial and government facilities, hospitality and medical facilities, oilrigs, maritime vessels and underground utilities.
