Q: Should I be concerned about carbon monoxide in my home?

A: Carbon monoxide can be an invisible threat to your family's health and safety. Though more commonly associated with fires and automobile emissions, carbon monoxide poisoning can accumulate in any home unless certain precautions are taken. Though we cannot recommend any particular brand, it is our opinion that installing a good carbon monoxide detector in your home is a wise decision. Certainly you should have your heating equipment checked periodically to insure it is running at optimum efficiency. At
A&M Mechanical Systems, Inc. we have over thirty years of experience in providing such maintenance. Please call us with all your heating system needs at (203) 674-0609 in Stamford, CT – or head to our simple, user-friendly Contact Form and tell us how we can best serve you.

Q: Why is my throat so dry?

A: Dry air in your home can make your throat feel dry, and cause or aggravate respiratory ailments. The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) recommends that your home maintain a humidity level between 30-60%. During extremely cold weather, your home loses humidity to the outdoors and may drop to as low as 10%. A humidifier adds moisture to your indoor air, and can help relieve ailments related to dry respiratory membranes.

Q: What are furnace ratings?

A: Furnaces are rated by their Annual Fuel Utilization Efficiency (AFUE). The AFUE is a calculation of the percent of heat produced for every dollar of fuel consumed. The higher the AFUE rating, the lower your fuel costs. All furnaces manufactured now must have at least a 78% AFUE.

If your furnace is 20 years old or more, it probably has an AFUE of just 50 to 60%. By 1990, the typical efficiency had risen to 80%. Some models today have an efficiencies of 95% or higher!

If your furnace is old and you are thinking of replacing it, going for the highest efficiency can be a good financial decision. The ENERGY STAR logo will help you quickly find furnaces with an AFUE of at least 90%. The highest efficiency models can cost a little more up front, but you'll save on fuel bills.

Example: Let's say you are currently spending $500 per year on gas, heating with a 65% furnace. Replacing it with a 95% efficient model instead of a less efficient 78% efficient model will save you around $75 / year in gas costs. The higher installation cost can often be paid off in just a few years as a result of the fuel savings. Furthermore, over the next 20 years, the high-efficiency model will result in 30,000 pounds less carbon dioxide (CO 2) getting dumped in our atmosphere.

Q: Why is it important to have regular maintenance on my home heating equipment?

A: Just as your car requires routine maintenance, so does your home heating equipment. The benefits of preventive maintenance extend the life of your equipment by keeping it running efficiently and smoothly. (Heating systems that run inefficiently can cost significantly more to operate.) Another benefit of preventive maintenance is the savings homeowners realize as they eliminate the costs associated with repairs - (repairs that were avoided because their equipment was properly maintained).

Regular service protects your warranty. A&M Mechanical Systems, Inc. takes time to thoroughly examine and adjust your system to ensure it runs smooth, clean and efficient – all year long.

Q: What are the benefits of indoor air quality systems?

A: It is estimated that 50% or more of all respiratory illnesses are either caused by, or aggravated by, poor indoor air quality. Air purification products use a variety of methods to help contribute to a healthier living environment.
