Furnace Replacement

Sometimes a repair is not sufficient to fix your furnace. Sometimes a new furnace is the most cost effective and energy efficient way to go. We will always be honest with you about a possible furnace replacement. We value our time and your money, we don’t want to perform repairs or service on an appliance that is need of replacement.

If you do need a furnace replacement, we know how overwhelming it can be. Here are some of the frequently asked questions about furnaces that we get from some of our Michigan residents:

What Are the Different Types of Furnaces?

Single Stage

This type of furnace has only one stage of operation. It can either be turned on or turned off.

Two Stage

This type of furnace has two settings, full and half speed. This is a more efficient way to heat and provides for better comfort because it can move the air at a slower pace.

Variable Stage or Modulating

This kind of furnace modulates the speed and heat output based on the temperature outside and the desired comfort level. This furnace only works as much as you need it, this makes it the most energy efficient type of furnaces.

What Is AFUE?

AFUE is the acronym for Annualized Fuel Utilization Efficiency, a measure of furnace heating efficiency. The higher the AFUE, the more efficient the furnace.

What Size Furnace Do I Need?

We can calculate the correct size furnace for your home. The number of BTUs or British Thermal Units, needed to heat your home is dependent on a number of variables. Contrary to what you might think, a bigger furnace may not necessarily mean more heating power for your home. Call us and we can set up an appointment to calculate the size furnace you might need.

Heat Pump Service, Repair and Replacement

We don’t just service furnaces. Many of our Michigan customers and the surrounding communities have heat pumps. Heat pumps are an energy efficient and environmentally friendly way to heat your home. If you want a heat pump installed or serviced or need repairs for your current one Eller Services is here for you.

What Kind of Heat Pump Do You Have?

A heat pump is a device that transfers heat from one place to another, from in to out or from out to in. It collects energy from a source and then transfers that energy into heat for your home. There are 3 basic forms of heat pump available.

Air Source

An air source heat pump collects energy from the air through a series of coils and transfers it into heat.

Water Source

A water source heat pump collects energy from water by running a series of pipes underwater and then transfers that into heat for your home.


A geothermal heat pump, also known as a ground source heat pump collects energy from the earth through a series of coils and transfers that energy into heat.

Gas Fireplaces

Eller Services also installs and maintains gas fireplaces. Gas fireplaces are an energy efficient, cozy addition to your Michigan home. If you are looking to install a new one, or maintain your existing one, we are the company for you.

Gas fireplace repairs and maintenance are potentially dangerous if you are unqualified to handle it. A gas fireplace has a gas line, pilot light, thermocouple and thermopile. When dealing with gas lines it is best to have a trained professional do the work to avoid any unnecessary danger. We recommend calling us for any problems you might be having.


Many of our Michigan customers have boilers in their homes and workplaces. Boilers are a complex appliance with a fairly basic purpose, to heat water and distribute it through your home. But just because it seems simple doesn’t mean its easy to fix.

The key components in your boiler are a burner, combustion chamber, heat exchanger and controls. The controls regulate ignitions, burner firing rate, fuel supply, air supply, exhaust draft, water temperature, steam pressure and boiler pressure. The water is heated inside the boiler and is pumped through pipes and delivered to the radiators around your home or building.

There are a number of places where things can go wrong in a boiler, it is best to have a certified professional diagnose the problem for you.

“Within 2 hours of my initial phone call, Matt, my technician, was at my house.
It took him 20 minutes to find the problem with my furnace, that my previous company, Thermal Pros, could not find in 4 days. He fixed the problem, and reinstalled my Nest (which Thermal Pros had removed), all in under an hour.
I am VERY pleased with Eller Services, and especially with my technician, Carl Stephens. They are now my heating/cooling/plumbing “go to” guys!”

“Ari went above and beyond installing my furnace. The others guys were
nice, but Ari stood out with his exceptional customer service skills. He made
sure I was happy with the installation and even had to come back to install the thermostat that I wanted. I would recommend this company and ask for
Ari if I needed anything done again.”
