Replace your furnace with Great Rebates

ACT BEFORE March 31st

There currently is an Xcel rebate of $750 towards 95% or higher furnaces. If you upgrade the blower to a high efficiency ECM blower you get an additional $100 for a max of $850 total. The $750 for 95% or higher is good until March 31, 2018. After that it will go back down to $300. The $100 ECM blower rebate is good on any furnace that utilizes an ECM even standard 80% efficient models, and does not currently have a deadline.

Also the $1150 rebate for high efficiency AC’s is still available with no current deadline. To get this rebate the furnace has have a ECM motor. This makes it a good time to replace your entire heating/cooling system with a total of $2000 in available rebates.

Your Benefits

Rebates help with the initial cost of equipment

Buying a 95% efficient furnace with EC Motor protects you from the potential of future rising energy costs

EC Motors are less expensive to run than conventional furnace fans

Quieter operation thanks to a lower fan speed

Improved comfort with less temperature fluctuation, maintaining a more even temperature

Your Average Savings

These upfront rebates help you save on the cost of more efficient equipment. You are also expected to save energy and money every year for about 18 years – the average life of a furnace.

Average sized 95% efficient furnace savings are shown here, compared to the baseline 80% efficient new furnaces. Here’s a breakdown of the savings:

$5.24 per dekatherms (unit measure for natural gas)
x $19.73 dekatherms per year for an average sized 95% efficient furnace
$ 103.39 per year
x 18 years
$1,861 in savings if energy prices remain the same

In addition, a new EC Motor in a new furnace could provide savings for about 18 years. If you put a new EC Motor into an existing furnace, the savings last for an average of seven years. That’s an estimated total of $585 if energy prices remain the same.

$0.103 per kilowatt-hour (unit of measurement for electricity)
x 812 kilowatt per year for an average sized furnace and AC system
$83.63 per year

Fancy Furnace with two stage gas system and ECM motor

We are servicing many “fancy furnaces” with 2 stage gas system and/or ECM motors and we are finding many installed by competitors that are failing to utilize and set up the furnace features, in particular the dip switches to advantage of all these features.
An ECM (electronic commutated motor) is a brushless DC motor with a permanent magnet rotor and a built in inverter.
DC motors are more efficient than AC motors.

The ability to move air rapidly and efficiently in HVAC systems is essential to achieving a cost-efficient comfort system. The electrical motors that were traditionally used in HVAC applications were AC induction style motors that were either single-or multi-speed — they’d run at one speed for heating, another for cooling, and sometimes a third speed for two-stage systems.

The problem with these types of motors is that they use a lot of energy because they run at full amp draw at all times. Also, since the motors run on high speed all the time, the noise levels are also high.

To address these two concerns — efficiency and noise — the electronically commutated motor (ECM) was developed. According to GE, an innovator in ECM technology, the wide range of the ECM motor, high efficiency, and programmability gives it a virtually unlimited range of performance characteristics.

ECMs (Electronically Commutated Motors) manufactured today are the best they’ve ever been, and can provide unprecedented airflow delivery to match the required BTUH of a heating and/or cooling system.

There are, however, some serious downsides associated with improper application of these motors in new and existing HVAC systems.

The Good:
When a furnace or air handler with an ECM is installed on a good duct system, coil, and filtration system with static pressures within proper design parameters, it can perform flawlessly. These systems can deliver precise airflow to match two-speed condenser designs and multi-stage gas furnace firing rates to deliver quiet, draft-free comfort in virtually any configuration.

These issues can be avoided with good pressure and airflow testing, both before and after equipment is replaced, and on every system you service. When you measure, you know. When you don’t measure, you’re just guessing that it will turn out OK.

Additional benefits of these brushless DC motors include low electrical consumption when operating within design TESP (Total External Static Pressure). When installed properly, systems with ECMs can improve dehumidification, reduce register noise, save energy, and provide trouble-free operation.

The Bad:
In marginal systems with higher-than-design static pressures — for example a .5–in. TESP rated furnace with ECM on a .8–in. TESP system — the motor still may be able to maintain airflow close to design. The tradeoff is higher velocities often cause a noisy system and some coil blow-off. The extra torque often required to overcome the higher statics results in higher electrical consumption. This reduces actual equipment EER, which means your customer won’t get the savings of the higher efficiency matchup.

High velocities and pressures created by ECMs on systems with dirty evaporator coils can also blow moisture off the coil surfaces into the supply ductwork. This can reduce the system’s dehumidification capability and cause numerous moisture-related indoor air quality issues.

The Answer:
These issues can be avoided with good pressure and airflow testing, both before and after equipment is replaced, and on every system you service. When you measure, you know. When you don’t measure, you’re just guessing that it will turn out OK.

Of course, there is more to this in terms of troubleshooting and solving these issues. The bottom line is that while the ECM is a great motor, as the servicing or installing contractor it’s your responsibility to make sure its application does not cause unintended consequences detrimental to the health and well-being of your customers’ homes and HVAC systems.



Make sure your furnace is working properly for fall

A cold front is coming and you do not want to be left out in the cold.  Now is the time to start the furnace and make sure it is running properly and kicking on when the temperature drops to the temperature where you have set the thermostat.  Furnaces need routine maintenance.  Over time the igniter can go bad, the flame sensor can get corroded, and the induced draft motor can fail to kick on the furnace.  Make sure you turn on the furnace and let it kick itself on by setting the temperature above what the thermostat is currently reading.  Let it run for awhile to make sure it is heating the house properly and that it is turning on and off correctly.  If  you have not had a furnace inspection or tune up in a while then now is the time to get one before something happens when winter really hits.

You should also check and or change your furnace filter at this time.  The typical life of a furnace filter is 3 months. The best way to gauge how often the furnace filter needs to be changed is to check it often and see how dirty it gets.

Do not let the furnace filter get to the point when you hold it up to the light and only 50% of the light is visible looking through the filter.

A good rule of thumb if you live in Denver, CO is to replace the filter in the fall when you start running the furnace. Replace it again at the end of January and if you forget to check it again at least you are changing it twice a year and this should be good enough to make sure it is pretty clean.  If you have central air conditioning, then it’s a good idea to check the filter monthly in the summer  to make sure it is clean as well.  Changing every 2-3 months is usually sufficient.

My air conditioner is not cooling the house down like it used to.

If your house is not cooling down like it used to then maybe your A/C has a refrigerant leak.

Air conditioner install

You may be running low on refrigerant due to a leak.

Refrigerant takes on the heat from your home and sends it outdoors. So without enough of it, the system can’t perform as well. An AC works like a refrigerator. In the summer the system extracts the heat from the home and sends it outside. That is how the house gets cooled down.

Signs your air conditioner needs more refrigerant.

  • Your ducts are blowing warm air even when your A/C is running and your thermostat is set to cool.
  • Water is on the floor in places it should not be.
  • Your home takes a long time cool down.
  • Ice is present on the indoor evaporator coil, the copper lines running from the furnace/coil area to the outdoor condenser.
  • Higher electric bills due to your air conditioner running longer to cool the home.
  • Refrigerant systems are supposed to be permanently sealed, so none should escape. In very few cases, systems with a leak makes a distinct hissing/gurgling sound, but otherwise everything will sound normal.  If you do hear any sound around the refrigerant line, you should turn off the a/c and call for service.

The safest approach when you think there’s a leak is to call for an air conditioner service technician. A trained technician knows how to seal leaks, and can recharge the refrigerant safely.

If your home is not cooling down, then an air conditioner service call and a refrigerant recharge could solve the problem.

Do you need your central air conditioner serviced or replaced?

Servicing or installing your central air conditioner: 

We are currently coming into air conditioning season.  Having an efficient cooling system will provide you the proper cooling output without having to pay extra when running the a/c.   You should turn on your a/c before it gets real hot to avoid having to wait to get service once it does get hot if it turns out you need service. 

How do you know if you need air conditioner service?

Do not turn the a/c on if the temperature outside is below 70 degrees. You could turn it on briefly if the temperature is above 55 to see if it is working.  Check to see if the air coming out of the vents is cool.

Set the thermostat to 72 if your home is currently at 75 and you are expecting for the temperature to go up into the 80’s. You may have to wait for 24 to 48 hours after starting  your a/c to dry out the humidity in the home and get a true feel for how the unit is operating.  If the home does not seem to be cooling down properly you are most likely in need of service.

Once the temperature outside really starts warming up you may want to cool your home down earlier in the day.  For example, If you are going to run your oven and cook, because of the heat gain from the oven you may want to turn on the a/c earlier in the day.  If you have the saver switch from Xcel they can start cycling your a/c power during high peak demands from 2 to 9 as needed.

Be sure to pull the shades on the windows and make sure you do not leave your door open so that the cool air does not escape.

Installing central air conditioning:

If you currently use a window air conditioning unit or a portable air conditioner to cool your home, you’re missing out on an opportunity for both comfort and efficiency. Central air conditioning systems are designed to operate with a much higher efficiency than window units.

Window units are not usually the right size for the room they’re in. That alone can cut efficiency by quite a bit. These portable a/c units are not held to the same efficiency standards as central air conditioners.

The correct sized air conditioner is important:

A new central air conditioner should be the right size for your home if you want it to cool the space efficiently. That means that it shouldn’t be too small, as it won’t be strong enough to cool the area and may run nonstop in an attempt to do so.

It also shouldn’t be too large. An air conditioner that is too large may start and stop repeatedly, which wears down the components and is not as efficient.  Our technicians can make sure you get the right sized unit for your home.

Check the SEER rating:

A/C units that have a higher SEER (seasonal energy efficiency ratio) are better.  These units will cost more upfront, but it’s worth it over the long term.  Choose a SEER rating of 16 or higher for the best results if you are planning on staying in the home.

Replace your thermostat batteries or you might be in for big problems.

Programmable Thermostat

Your thermostat should give you a warning when the batteries are low and make sure you replace them.

A friend of ours went on vacation and when we went to check on their home a few days later it felt like an oven.  It was 120 degrees inside.  It turns out that with some furnaces if they are running when the batteries die then the furnace just keeps running as it does not know to turn off.

If this happened to your house  it can cause all kinds of problems.  The toilet is likely to leak as the wax rings that provide the seals will melt.  There can be other issues and even the possibility of an explosion so make sure you change your batteries.

How Often should I change my furnace filter?

The typical life of a furnace filter is 3 months. This can vary based on how much the fan is running, how dirty the ducts are, and the lifestyle of the tenant/homeowners. Pet hair and dander can be a significant factor as well. The best way to gauge how often the furnace filter needs to be changed is to check it often and see how dirty it gets.

You should never let the filter get to the point when you hold it up to the light and only 50% of the light is visible looking through the filter.

Furnace Filter

A good rule of thumb if you live in Denver, CO is to replace the filter in the fall when the furnace first starts running  a fair amount.  Replace it again at the end of January and if you forget to check it again at least you are changing it twice a year and this should be good enough to make sure it is pretty clean.  If you have a two stage high efficiency furnace the fan will tend to run more often so you may want to change it January first and again in Mid March.
If you have central air conditioning, then it’s a good idea to check the filter monthly in the summer  to make sure it is clean.  Changing every 2-3 months is usually sufficient.

It is more important to check and replace the filter than to pay extra for an expensive filter you only change once a year. Having a clean filter will extend the life of your furnace and can save you a significant amount of money by following a maintenance schedule.




Draft Inducer Motor for your furnace

Is your furnace not starting up and maybe making a funny sound like it is trying to start up?  Perhaps you have shut it off and then turned back on. Maybe you just turned the fan on and it works.  You may be in need of a new induced draft motor or draft inducer motor. This motor is what creates a draft through the heat exchanger. Air and gas are drawn through the front of the furnace and conveyed to the flue connector. What you have is a whole assembly. In most cases the entire assembly is what gets replaced. In some rare cases you can replace just the motor which is cheaper but takes longer to do. When replacing the assembly it is important to replace the gasket that goes between the assembly and the heat exchanger manifold. The gasket is usually fiberglass or fire rated foam. Modern furnaces have this motor as well the circulating or blower motor. Out of the 2 motors, the inducer motor typically is the one that fails first. The bearings start to wear out making the operation noisier and eventually they fail and the motor stops turning. I have seen motors with noisy bearings run for a long time (years) and in other cases no increased noise is noticed before the motor fails.

The induced draft assembly is typically made of steel or metals such as the one in the picture.

They often  develop rust and wear out. Replacing the draft inducer motor assembly is the only way your furnace will operate.


How much should I expect to pay to replace my draft inducer motor assembly?

Depending on the make and model expect to pay between $500 and $800 for residential gas furnaces.  At Tobin you can count on us to tell you what the problem is and give you a fair reasonable price ti install a new draft induced motor.
