Frequently Asked Questions


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’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.

What’s important about having the right size heating and cooling system?

When heating is required in your home, an oversized heating system will cycle frequently which can lead to drafts and inconsistent control of the room temperature. Additionally, when a central humidifier is installed in the heating system, an oversized furnace will not allow the humidifier to run enough to create the right amount of humidity in your home. Conversely, an undersized heating system will run constantly, not reaching the desired room temperature and wasting energy.

When cooling is required in your home, an oversized air conditioner will reduce the room temperature, and not adequately remove humidity. This causes you to feel cold and clammy. When the air conditioner is too small, it will it will run near constantly, not reaching the desired room temperature

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. 410A is the refrigerant of choice to replace Freon (R-22). It is environmentally friendly and cools equally to R-22.

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.

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.

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 should I look for in a good contractor?

Make sure the contractor is licensed and insured in the state of Michigan. Technicians should be certified. Contractor must file city permits for all installation work.

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.

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 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.

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. View our Gold Maintenance Plan
