Frequently Asked Questions


Can I make one room cooler than another?

A zoning system can divide your house into separate comfort zones. Ideal for 2 story homes with one system, a zone control system utilizes zone dampers to adjust air flow in different zones based on how the thermostats are programmed. Another energy saver since you don't cool or heat rooms that are not being used.

How can I get better efficiency from my current equipment?

Adding a Comfort Control Center will lower humidity levels by utilizing probes located in the evaporator coil and return air stream to sense the temperature differential and slowing the blower speed. By slowing the blower, a colder evaporator coil condenses water vapor quicker, which lowers humidity in the structure. This also allows the blower to use less energy since it isn't at full speed unless needed.

How can I make my air conditioning system "green"?

Whether it's high efficiency compressors and heat exchangers that consume less energy, refrigerants like 410A that don't deplete the ozone, or dehumidifiers and filters that improve a home's air quality, we can recommend a wide range of options to help save energy and money that are environmentally friendly.

Is it true that a thermostat can save me money?

Definitely. A programmable thermostat can maintain accurate temperatures and be programmed to adjust temperature settings for times when no one is home. This is an inexpensive and quick addition that can make a big difference.

My attic insulation and ducts are wet - what causes this?

Duct sweating could be a problem if duct work is not insulated properly. Over time insulation on the ducts breaks down or is damaged by rodents. This will also cause the system to operate below its potential. Inspection of the duct work is part of our maintenance program; go to our maintenance contracts page for more info.

Using pleated filters improves air quality, right?

Pleated filters restrict the intake air flow and cause your system to perform below its capability. We recommend AprilAire cleaners to keep dust and dirt from reaching your heating and cooling equipment allowing it to perform at peak efficiency for the entire life of the filtering media, reducing your maintenance costs while improving air quality.

Water is dripping from a drain outside my house - is that normal?

This could be a sign that your main drain is clogged. Over time, mineral deposits and slim builds up and the water will be directed into the emergency drain pan and out this emergency drain. If left unattended, it could cause many problems such as sheet rock damage and rust damage to the emergency drain pan.

What does R-value mean?

Insulating performance is measured by a common standard referred to as the R-value. R-value measure resistance to heat flow and is usually determined by the thickness of the insulation. The higher the R-value, the greater the insulating power. The US Department of Energy recommends a minimum of R-30 in the attic. Call today for an evaluation of attic insulation and more info on Owens Corning blown-in insulation.

What is 410A refrigerant and why does it matter?

Like a heart, your home comfort system must circulate a fluid - called a refrigerant - to function properly. Refrigerants are formulated to circulate in a system for years. That's great for ensuring air conditioners and heat pumps last a long time. But it's a concern if the refrigerant escapes into the atmosphere where it can cause problems.

In January 2010, the U.S. Clean Air Act requires all new residential air conditioners and heat pumps to use refrigerants that do not affect the atmosphere's ozone layer. R-410A is a proven refrigerant that has been approved since it's more environmentally friendly and doesn't harm the ozone layer. R-22 refrigerant, which is still available in limited quantities for servicing existing R-22 equipment, will be phased out and R-22 equipment will no longer be sold after January 2010.

What is SEER and why is it important?

The efficiency of air conditioners and heat pumps is determined by the Seasonal Energy Efficiency Ratio (SEER) rating. The higher the SEER rating, the more energy-efficient the product is and the greater the potential for savings on energy costs. If your equipment is more than 10 years old it most likely has a SEER rating of 10 or less. This is regulated by the EPA and the current minimum allowable SEER rating is 14.

What kind of warranty comes with new equipment?

Warranties vary depending on the manufacturer and the model of equipment installed. They range from 5 year to lifetime warranty so we recommend you do some research and choose the equipment with the warranty and SEER rating that best suits your needs. Details are usually available on their websites so check out our home page for links.
