Frequently Asked Questions
How long does it take to install and new heating or air conditioning unit?
We are asked this question a lot. Typically, we can have a new replacement in your home between 4 to 8 hours.
I need to replace my air conditioner, but my furnace works just fine. Is it true they need to be replaced at the same time?
Think of your air conditioner and furnace as part of a total system. That system will work better, longer and more efficiently if all of its components are matched in capacity and efficiency. For example, your new air conditioner will be rated with a specific SEER efficiency rating. Your existing furnace and indoor coil can significantly impact this efficiency because of technology differences and an imbalance in capacity. Your indoor coil may even be dirty and blocked with particles, which further hinders its performance. A mismatched system mixes old technology with new, decreasing your overall comfort and diminishing performance.
Why are rating numbers important?
Rating numbers indicate the efficiency of heating and air conditioning equipment and are directly related to the amount of energy a specific model uses. The higher the rating, the more efficient the product, and the lower your energy bills can be. The federal government establishes rating guidelines and sets minimum efficiency levels. For cooling, the rating is SEER (Seasonal Energy Efficiency Ratio). For heat pumps, the rating is HSPF (Heating Seasonal Performance Factor). Gas furnaces are rated with AFUE (Annual Fuel Utilization Efficiency).
What’s the difference between a manufacturer’s limited warranty and an extended warranty?
A manufacturer’s limited warranty is the warranty that a product leaves the factory with. Typically, it covers specific parts for a limited period of time. Extended warranties are optional and are generally purchased at the same time as the equipment. Optional extended warranties cover all parts and may even include labor. There are a variety of optional extended warranties to choose from, but all are designed to offer long-term peace of mind.
My children have allergies. Is there a way to improve the indoor air quality in my home?
An electronic air cleaner is 40 times more effective than a standard throwaway filter in removing unwanted particles from your home. Particles such as pollen, dust, bacteria, tobacco smoke, cooking smoke, animal hair and dander prevent your indoor air from being as healthy as it could be. An electronic air cleaner with a washable electronic cell is up to 99% effective at removing these airborne particles. An electronic air cleaner also protects the operating efficiency of your heating and air conditioning system and keeps your furniture, drapes, carpet and walls cleaner, as well.
How can I control my energy costs?
If you’re shopping for a new heating and air conditioning system, the best way to control your energy costs is to purchase a high efficiency variable speed system. Variable speed means your system varies its speed depending on your home’s heating and cooling requirements. Because of this, variable speed systems are more efficient than single-stage systems. Efficiency ratings also matter. When you match a 14, 16 or 18 SEER air conditioner or heat pump with a variable speed furnace or air handler, you can rest assured that you’ve selected a home comfort system that is one of the quietest and most energy efficient available today.
How do I know what size system I need for my home?
One of the first things a Lennox dealer will do is conduct a complete energy analysis of your home. By measuring windows, checking insulation, ductwork and building materials, as well as a variety of other factors, he can determine the right size system and equipment for your home. He’ll even ask you questions about your existing comfort challenges. For example: Are there rooms in your home that are always too hot or too cold? If this is the case, you may need ductwork modifications in addition to a new system.
