Heating & Cooling Frequently Asked Questions
-
What should I look for in a good
Michigan contractor?
- Make sure the contractor is licensed and insured in the state of Michigan.
- The contractor should use name brands.
- Technicians should be certified.
- Contractor must file city permits for all installation work.
- Contractor should make you feel comfortable.
- Contractor should have excellent references.

What is an energy-efficient
furnace?
Simply, if you have an 80% efficient furnace, it basically means for every
dollar spent on fuel, 80 cents is used to heat the home and 20 cents is lost up
the chimney.
Furnaces are rated with efficiency levels. What does this mean?
Furnaces are rated with Annual Fuel Utilization Efficiency (AFUE). The
minimum AFUE number is 80. The efficiency improves with a higher AFUE
number.
-
What is the difference between an
80% efficient furnace and a 90% efficient furnace?
Both furnaces will heat the home equally well, but the 90% furnace is more
efficient, saving you approximately 10% in operating costs.
- 80% furnaces typically vent up a chimney because they have high exhaust
temperatures that remove products of combustion.
- 90% furnaces have such a low exhaust temperature that they have to be
power-vented directly outside in PVC pipe.
-
What is a chimney liner and why is
it needed?
A chimney liner is made of metal and it is placed in an existing brick
chimney so everything vents properly. If you are replacing an old, inefficient
furnace with an 80% or 90% efficient furnace, you will need to have the chimney
liner replaced as the old chimney flue is too large for new vent requirements.
If the chimney is metal, it usually does not need a liner.
-
Do all chimneys need a chimney
liner?
Almost all brick chimneys need a liner because the flues are generally too
large. Metal chimneys usually do not need a liner.
-
How often should I change my
furnace filter?
If your furnace has a standard (replaceable) filter, change it once a month.
If you have an electronic cleaner, clean it every three months. If you have a
whole house HEPA cleaner, you need to replace it once a year.
-
Another company installed our
furnace. Now, they won’t come out and service it. Will you?
Of course. We charge a diagnostic fee; if we discover a problem that needs
correcting, we'll explain it to you and quote a flat fee to do the work. That
fee will include a one-year parts and labor guarantee. We'll do the same with
air conditioning and other products installed by companies that won't follow up
with maintenance service.
-
My furnace won't start - and we're
getting cold.
Reset the furnace - the reset switch looks like a light switch that's on your
furnace. To do this, turn the switch "off" for 20 seconds, then back on. Even if
this works, be sure to call us to check your furnace. The fact that it did not
start on its own indicates a problem.
-
I'm sure we need a new furnace,
and our air conditioner is about the same age. Is it worth getting both at the
same time?
Definitely. We can save time - which saves you money by sending our
installers only once.
Furnaces are rated with efficiency levels. How are air conditioners
rated?
Air conditioners use a Seasonal Energy Efficiency Ratio (SEER). The minimum
is 10 SEER, but should be 13 SEER. The efficiency improves with a higher SEER
number. Every time the rating increases by one point, the efficiency increases
by approximately 10%. Beginning January 22nd 2006, all newly manufactured
equipment will require a minimum SEER of 13.
-
Is it true that the government is
phasing out Freon (R-22) for central air conditioners like it did for Freon
(R-12) that was used in window units, refrigerators and automobiles?
Freon (R-22) central air conditioners cannot be manufactured after the year
2010. The Freon (R-22) refrigerant cannot be manufactured after 2020. Since
Freon (R-22) will be made on a limited basis, it will become very expensive,
just like Freon (R-12).
-
What is replacing Freon (R-22)?
410A is the refrigerant of choice to replace Freon (R-22). It is
environmentally friendly and cools equally to R-22. You may have heard it called
PURON–the brand name from Bryant.
-
What's the best way to get my air
conditioning running in the spring?
- Remove the air filter on the furnace and clean it.
- Turn the damper on the furnace to "Summer."
- If you have a humidistat, turn it from 35% to 0%.
- Twenty-four hours before starting your air conditioning, turn the disconnect
back on.
- Wash the condenser unit (that's the unit outside your house). Set your hose
nozzle for a fine spray of water and spray from the top down.
- Turn on your air conditioning and enjoy the cool comfort inside.
-
How often should I have my air
conditioner checked?
Both Furnaces and Air Conditioners should be checked yearly to ensure
warranty and guarantee highest efficiency.
-
How do I clean an electronic air
cleaner?
Spray it with Fantastic or 409 cleaner, let it dry and reinstall it. Or put
it in your dishwasher. Use a soap that leaves no film and be sure to protect the
thin "piano" type of wires in the cleaner from the spikes in the dishwasher
tray. One way is to set the cleaner on top of glasses that are placed over these
spikes in the dishwasher.
-
What can I do to improve my
indoor air quality?
- Keep windows and doors closed during prime ragweed season.
- Ventilate your home. Use exhaust fans when you cook or shower.
- Filter the air with an air cleaner and make sure you clean the filter
regularly.
- Treat the air with an ultraviolet air treatment system.
- Maintain the right relative humidity between 45%-65% as recommended by the
EPA.
