We like our clients to be informed and make informed choices, because these choices will last for an average of 8 to 10 years. We encourage questions! Here are some frequently asked questions. If you have other questions, give us a call (630) 279-4822 or Email us! Is RPM licensed? We are licensed in the state of Illinois - Feel free to ask us for a copy of our business license. Is RPM insured? RPM carries liability insurance and workman's compensation to protect our company and our clients if something happens. We highly recommend clients to ask all their contractors for a copy of their insurance. Did you know that if a contractor gets injured in your home without insurance, you can be held responsible? Are proper permits included? RPM can pull permits for you or the client or client's architect can pull them from the village/city - call for details. Do we offer 24 Hour Emergency Service? YES! No exceptions! Call us 24 Hours a day - 7 Days a week! Someone is always on call to help our customers. You will reach a service technician after hours - NOT an answering service/receptionist. Who answers the telephone? On weekdays, during normal business hours, our office staff answers the phones. They attend continuing education classes just like our installers and technicians. They are knowledgeable to answer all your questions. After hours, our full time service technicians are on call and answer the phones. We believe that if you are calling us with a problem to have serviced, you would like to talk to someone who can answer your questions, not just take a message or schedule an appointment. Do we provide references? YES! We believe our best advertisements are our satisfied customers. Read what they are saying or call/email us for a list of references We at RPM realize that indoor comfort systems are a big expense as well as an investment - we want our clients to make educated choices when purchasing new indoor comfort systems and in choosing the right contractor. Here are some things to consider when comparing hvac contractors, comfort systems and cost. Please feel free to call us (630) 279-4822 or email us if you have questions regarding any comparison you are doing on systems you are considering. There are basically three ways you can compare the performance of different models and brands: · EFFICIENCY: How much energy they use to heat or cool your home?  · SOUND LEVELS: How much you notice their presence? · COMFORT: How they make you feel?  EFFICIENCY: Furnace: The efficiency of a furnace is measured in a rating known as AFUE (Annual Fuel Utilization Efficiency). A lot like your car’s miles per gallon rating, AFUE tells you how efficiently the furnace converts fuel (gas or oil) into heat. An AFUE of 80% means that 80% of the fuel is used to heat your home, while the other 20% basically goes up the chimney. In 1992, the government established a minimum AFUE rating for furnaces installed in new homes at 78%. (In contrast, many furnaces manufactured before 1992 had AFUE ratings as low as 60% — so nearly half the fuel was being wasted.) Furnaces with AFUE ratings of 78% to 80% are considered “mid-efficiency”; those with ratings of 90% or higher are known as “high efficiency.” The maximum furnace efficiency available is around 96.6%. In general, the higher the efficiency of the furnace, the more it will cost but the less fuel it will use to heat your home. If you have an older furnace (with an AFUE of about 60%), you could save up to 60% on your heating bills by replacing it with a new high-efficiency furnace. So the cost to replace your old, inefficient furnace is paid back through lower utility bills. If you live in a cold climate, you could see a payback in a few short years. If you live in a moderate climate, it might make more sense to purchase a mid- efficiency furnace. Your dealer can use heating data from your area to help you determine about how long it would take you to recover the additional cost of a high-efficiency model in energy savings. (Of course, after the payback, you continue to save on your energy bills for the life of the system.) Heat pumps and air conditioners: Cooling efficiency for air conditioners and heat pumps is indicated by a SEER (Seasonal Energy Efficiency Ratio) rating, which tells you how efficiently a unit uses electricity. The higher the number, the greater the efficiency. The typical SEER rating of units manufactured prior to 1992 is about 6.0. In 1992, the government established the minimum cooling efficiency standard for units installed in new homes at 10.0 SEER. High-efficiency units have a SEER of at least 12.0; the maximum available is about 17. Heat pumps also have heating efficiency ratings, indicated as an HSPF (Heating Seasonal Performance Factor). In general, the higher the HSPF rating, the less electricity the unit will use to heat your home. The 1992 government minimum heating efficiency standards for new heat pumps is 6.8 HSPF. Most heat pumps manufactured before 1992 have HSPF ratings below 5.0. Today, an HSPF of 7.5 or higher is considered “high-efficiency”; the maximum available is 10.0. (If you want to get real technical, the actual heating efficiency of air-source heat pumps is well over 100%, because they “steal” heat energy from the outside air — instead of using just electricity — to heat your home. So you get much more out of them than you put in.) As with furnaces, higher efficiency in heat pumps and air conditioners usually means higher cost but lower utility bills. If you live in a warm and/or humid climate, you will probably see the higher cost of a high-efficiency air conditioner or heat pump paid back (through lower utility bills) in a few short years. Ask your dealer to help you determine about how long it would take you to recover the additional cost in energy savings. Of course, after the payback, you continue to save on your energy bills. There’s one other factor that affects the efficiency of your air conditioning or heat pump system: the indoor coil. (Your heat pump or air conditioner is a “split system,” which means that there is an outdoor unit, or condenser, and an indoor unit, or evaporator coil.) If your condensing unit is not matched with the proper indoor coil, it may not give you the stated SEER and/or HSPF ratings and could even develop performance problems. (It’s kind of like putting two new tires on one side of your car and leaving the old, worn-out ones on the other side. You’d probably be disappointed with both the performance and the miles per gallon you get.) When you’re replacing an existing system, make sure you replace both units so your new condensing unit will give you optimal performance, efficiency and comfort. SOUND LEVELS  Air Conditioners and Heat Pumps: There’s a good chance you won’t ever think about the sound level of your air conditioner or heat pump ... until, that is, you try to enjoy a quiet conversation with some friends in your back yard. Sometimes noise from condensing (outdoor) units even interferes with your peace and quiet indoors, so it’s a factor you should at least look at when you’re comparing different models. The sound level of outdoor units is measured in bels (similar to decibels), on a scale from 0 (barely perceptible sound) to 13 (the threshold of pain). Most air conditioners and heat pumps operate at 8 to 9 bels; some units’ ratings are as low as 6.8. That may not sound like a wide range, but consider this: 9 bels sounds 10 times louder than 8 bels. That means one 9-bel air conditioner is as loud as 10 units rated at 8 bels. So we think taking the time to compare bel ratings is pretty sound advice. Furnaces: There isn’t a standard sound rating system for furnaces like the bel system for condensing units, so it’s difficult to compare models. However, models that have two-speed or variable-speed operation typically also offer lower operating sound levels, because there is less noise from the blower motor and from air turbulence at lower speeds. Carrier’s variable-capacity models even have a “ramp-up” feature that gradually introduces warm air into your ducts, helping prevent the “creaking” noises that come from ducts expanding and contracting. Since two-speed and variable-capacity models normally run on “low” speed up to 90% of the time, you’ll find they’re a sound solution when you want to enjoy peace and quiet. COMFORT  Furnaces: For furnaces, the same features of multi-capacity models that provide lower sound levels also enhance your comfort. By operating on low speed up to 90% of the time, two-speed furnaces run for longer periods of time than single-speed furnaces. That means fewer on/off cycles, fewer drafts (from the blower kicking on) and much smaller temperature swings -- only one or two degrees instead of the four-degree swings common with single-speed furnaces. Plus, better air circulation helps prevent air “stratification” — warm air rising to the ceiling and cold air settling on the floor. In short, you get consistent, even heat throughout your home. Variable-capacity furnaces also offer “smart” motors than can monitor your home’s comfort needs and automatically adjust the volume and speed of air to provide the greatest comfort and the most efficient heating or cooling. They provide the ultimate combination of comfort, efficiency and quiet performance. Air Conditioners and Heat Pumps: Some air conditioners and heat pumps offer additional features that provide greater comfort. Two-speed units can run on low speed (using 50% of the energy) up to 80% of the time, so they offer the same benefits as multi-capacity furnaces — fewer on/off cycles, fewer drafts and much smaller temperature swings. You also get better air circulation, for even, consistent cooling and/or heating throughout your home. Plus, if you purchase a multi-speed or variable-capacity furnace or fan coil with your unit, you will enhance both the comfort and the efficiency of your air conditioning or heat pump system even further.
