Q. Can you tell me exactly how much this job will cost me?

A. In our years of experience we have found that our customers prefer an accurate price based on their exact problem. While other companies may quote you an hourly rate that sounds cheap, the workers they send will come out intent on staying at your location as long as they can in order to make more money.


Why? Because they are getting paid by the hour. So what's the rush? And while other companies may give you a quote over the phone, you must understand that the quote will very likely change once the service technician is at your home. We don't think that either is fair to you. By allowing us to send a plumber to your home for an absolute "free estimate" he can then diagnose your problem in person. Only then will  he and you know exactly what it will take to get the job done and the price to do it.


At Aaron's Heating Services, you approve the price before any work is performed. We make sure you have all the information necessary to make the best decision possible with the options we give. You will always have a choice and never have to deal with getting an unapproved invoice after the work is completed. We are very upfront with our costs to avoid the customer any surprises. Our trained technicians will walk you through each step of the way to ensure your complete satisfaction.


Q. Why is my bill so big?

A. This is what happens when you get charged for "time and material" as the technician gets paid more the longer it takes him. Only at Aaron's Heating Services do you get straight-forward pricing. This shows you the EXACT amount it will cost so that you can decide before the work even begins.


Q. Are your employees licensed?

A. Yes, with over 20 years of experience we have amongst our employees, we are licensed by the State of Illinois. We also are bonded and insured. Our technicians attend a continuing education class each year required by the State of Illinois.


Q. I have never had to call a heating specialist before, what should I expect?

A. Plumbing Services is serious about customer service and safety. We background check and drug screen every employee to ensure we have the best personnel in your home. Your first interaction with our company will be a friendly voice of one of our professional customer service people eager to assist you in setting up an appointment.


Our technicians will call you before heading to your home to ensure you are home and to let you know who is coming. Our technician will arrive in a truck within the time frame we have agreed to in your schedule. You will be greeted with a clean, friendly representative from our company who will not only respect you and your home but listen to you so we can come up with the best solutions for you. We guarantee your satisfaction so in the event we don't meet you expectations simply lets us know and we will make it right.


Q. My husband and I work during the week and cannot stay home to wait  for a heating specialist, do you have any options for us?

A. We operate 7 days a week with a full office staff and technicians ready to exceed your expectations of service. We do not charge additional for Saturday or Sunday appointments so please call now to set one up today.


Q. What if my job turns into a larger project, do you have any payment options?

A. We offer easy to apply for financing with approval on the spot. Our customers often have multiple jobs for us to take care of and love the option to spread out the cost with financing. We also accept all major credit cards, cash and checks.


Q. I am a busy person and in the past I have had contractors who make multiple trips to fix the problem, do you operate that way?

A. We arrive at your home in a fully stocked super truck with all the equipment we will need for most home repairs. If we don't have it with us, one of our delivery vehicles will bring it to your home in minutes so we can be efficient with your time. On the other hand, many of our customers have us do while you're here work and we are happy to stay and take care of anything they want in one trip. This saves you money because we are able to group the jobs together and discount the overall cost.


Q. What kind of warranty or guarantee do you offer?

A. Other heating specialists have a "Concrete Guarantee"- when their truck leaves your concrete driveway their guarantee expires! Not with Aaron's Heating Services! With us you have a 100% SATISFACTION 2-YEAR GUARANTEE.


Q. Do you offer 24 hour emergency service?

A. We are available 24 hours a day/7 days a week to help with all your heating issues. Call us anytime to be connected to a live person that can help resolve your heating problem.

Q. Why should I replace my existing furnace or air conditioner?
A. You may wish to consider replacing your furnace or air conditioner if it is old, inefficient or in need of repair. Today's systems are as much as 60% more efficient than those systems manufactured as little as ten years ago. In addition, if not properly maintained, wear and tear on a furnace or air conditioner can reduce the actual or realized efficiency of the system. If you are concerned about utility bills or are faced with an expensive repair, you may want to consider replacing your heating or cooling equipment rather than enduring another costly season or paying to replace an expensive component. The utility cost savings of a new unit may provide an attractive return on your investment. If you plan on financing the purchase, the monthly savings on your utility bill should be considered when determining the actual monthly cost of replacing a system. The offsetting savings may permit you to purchase a more efficient system.

Q. How expensive are air conditioners and heat pumps?
A. Many factors affect the cost of a heating or air conditioning system, including the size of your home, the type and condition of the ductwork installed and accessories you might need such as a thermostat or an electronic air cleaner. We have a complete range of systems and accessories available to meet all your needs, including your financial ones! We will be happy to assist you in finding the right system to meet not only your comfort needs but also your household budget.

Q. How do I select the right heating and cooling products?
A. First, make sure the unit is properly sized. Your comfort consultant will provide a load calculation for your home. Next, consider any comfort issues in the home. Some products can reduce air stratification and uneven temperatures from room to room. If you have allergies, an indoor unit with an ECM motor will allow you to circulate the air in your home continuously while filtering the air for about the same cost as operating a standard light bulb. Finally, know your budget parameters and the efficiency of the system being proposed. Does the system offer a payback? In other words, will the monthly savings over time offset the cost of the new unit or efficiency option being considered?

Q. What is involved in replacing an old furnace or air conditioner?
A. Aside from the placement of the new equipment, we will inspect several items and make a determination of whether or not these items need to be supplied or replaced. Some of the items include: ductwork, insulation, refrigerant piping, electrical service, wiring, thermostat, condensate piping, flue piping, flue terminations, chimney liner, slabs, filter, driers, registers, grills, drain pans and evaporator coil.

Q. What is involved in installing a new heating or air conditioning system?
A. If a forced air system is being added to the home for the first time, most of the items noted in the previous Q. and A. may be required to install the new system. Besides the equipment, the most significant component is ductwork. The ductwork can be either metal or fiberglass ductwork. The ductwork needs to be properly sized to deliver the right amount of air to each room. The ductwork consists of supply and return ductwork. The supply duct is attached to the outlet of the furnace or air handler and delivers air to individual zones in your home. We will determine the size of the ductwork going into a space by the amount of air that needs to be delivered to the space.

Q. How long can I expect a new furnace or air conditioner to last?
A. If you have a qualified technician perform regular preventative maintenance and service suggested for your unit, industry averages suggest that an air conditioner should last 12-15 years (sea coast applications may be less) and a gas furnace should last as many as 20-25 years.

Q. What are some preventative maintenance things I should be aware of?
A. With the proper attention, heating and cooling systems can keep you comfortable year-round. Heat pumps and oil-fired furnaces and boilers need a yearly professional tune-up. Gas-fired equipment, on the other hand, burns cleaner and can be serviced every other year. A close inspection will uncover leaks, soot, rust, rot, corroded electrical contacts and frayed wires. In furnace (forced-air) and boiler (hot-water) systems, the inspection should also cover the chimney, ductwork or pipes, dampers or valves, blower or pump, registers or radiators, the fuel line and the gas meter or oil tank — as well as every part of the furnace or boiler itself.

Next, the system should be run through a full heating cycle to ensure that it has plenty of combustion air and chimney draft. Finally, cleaning the burner and heat exchanger to remove soot and other gunk will prevent such buildup from impeding smooth operation. For the burner, efficiency hinges on adjusting the flame to the right size and color, adjusting the flow of gas or changing the fuel filter in an oil-fired system. A check of the heat pump should include an inspection of the compressor, fan, indoor and outdoor coils and refrigerant lines. Indoor and outdoor coils should be cleaned, and the refrigerant pressure should be checked.


Q. How important is adding humidity to my home?

A. As we heat our homes, the air has a tendency to dry out. This dry air can damage the woodwork and furniture you have in your home as well as zap the moisture from your skin. Dry air even makes you feel cooler because your body senses heat as a combination of temperature and humidity. Adding humidity to offset this drying process will improve your comfort as well as preserve the woodwork in your home. As an added benefit, you may actually be able to lower your thermostat a couple of degrees. You will not only feel warmer but you may actually lower your heating bill!


Adding this much needed moisture will make your home a healthier and more comfortable place to spend your time. Contact us and we will be happy to discuss your choices and provide you with pricing for adding a humidifier to your home.


Q. How important is an air filter in my heating and cooling system?

A. It's a fact: the trapped air we breathe in our homes can be loaded with dust, pollen, plant spores, and other pollutant particles. In many cases, it's worse than the air outside.


Q. After my air conditioner runs for a while, ice forms on the big pipe outside and it stops cooling. What could be the problem?

A. More than likely, it's either low on refrigerant or low on airflow. As a homeowner, replace your filter and allow the unit to thaw out. If the problem reoccurs, call us to schedule service on your system. We recommend having annual maintenance performed to keep your systems in peak operating conditions.


Q. How big of a furnace or air conditioner do I need for my home?

A. The only way to size a furnace or air conditioner for your home is to do a heat load calculation. The capacity needed is based upon how quickly your home gains or loses heat, not by square footage alone. ACCA's Manual J is an industry-approved method that we use to insure the proper system is selected for you.


Q. What does SEER and AFUE mean?

A. SEER stands for “Seasonal Energy Efficiency Ratio”. Basically it tells you how efficiently it converts electricity to cooling comfort. The higher the SEER rating, the more efficient the system. By federal law all units must be a 10 SEER or higher. We recommend having a representative come to your home and perform a heat load calculation to insure the proper size unit is installed. This is a free service to our customers that may help you save money and increase your indoor comfort.


AFUE stands for “Annual Fuel Utilization Efficiency”. This rating tells you how much of your heating dollars are converted to heat energy put into your home and how much is lost up the flue pipe. Most older furnaces are 50% to 60% efficient. That means that for every dollar you spend for gas from your utility company, $.40 to $.50 are being sent up the flue pipe to the outdoors. Federal law mandates that all furnaces being produced today be at least 80% efficient. We offer several different sizes of furnaces up to 96% efficient. That means that for every dollar you spend on gas from the utility company $.96 is converted to heat your home and only $.04 is sent out the flue pipe.


We can visit your home, perform a heat load calculation and recommend the proper system to keep you comfortable and save you money. In many cases, homeowners have saved enough on their utility bills to more than cover the investment of a new comfort system.


Q. Why is the upstairs of my house always hotter in summer and cooler in the winter when I only have one unit? What should I do?

A. Heat rises, thus the reason it's hotter in the summer. Assuming the system was sized and installed correctly, you should consider installing a zone system if possible. Sometimes the addition of return air ductwork will help improve air movement and help make upper levels more comfortable.


Q. Should I get my ducts cleaned?

A. Cleaning your ducts may be beneficial in improving your indoor air quality. A premium whole-house duct cleaning will help decrease the spread of contaminates in your ductwork and home. New construction homes can benefit from having the ductwork cleaned to remove drywall dust, sawdust and other debris from the construction process.


Q. What's that black stuff on my ceilings and vents?

A. Burning candles can be the culprit for the black on your walls and ceilings as well as polluting the air your family breathes. Keep wicks trimmed to no longer than 1/4th of an inch to help reduce soot from the candles.


Q. Should I be concerned about carbon monoxide?

A. Carbon monoxide, also known as the silent killer, can pose a serious threat in some instances and is yet another reason to have your furnace and water heater inspected by us. A carbon monoxide detector is a wise investment. We offer a high quality carbon monoxide detector that has a 5-year warranty.


Q. During the winter the fan occasionally shuts off on my heat pump outside unit, then restarts with a big puff of smoke. What is wrong with it?

A. Nothing is wrong with your unit. What appears to be smoke is steam from the outdoor coil after it completes a defrost cycle. After extended run times the outdoor unit will start to build frost or ice on the coil. The system is designed to go in a defrost mode when needed to clear the ice away and keep the efficiency level up.


Q. I have friends and relatives that have installed UV lights on their furnace. What are they for and why do I need one?

A. UV is the abbreviation for ultraviolet. Located in the return air ductwork and by the indoor cooling coil, the ultraviolet air treatment system continuously emits high – intensity ultraviolet (UV) energy. The energy eliminates (kills) a very high percentage of airborne bacteria and germs passing over the UV light field inside the ductwork. The UV light mounted next to the indoor cooling coil will help eliminate the growth of mold, mildew and other contaminates from the drain pan and coil surface. We recommend installing non-ozone-producing UV products.


Q. My furnace and air conditioner are both new. Do I really need to have it cleaned?

A. Yes! Even though your system is new, it still needs to have annual maintenance performed. This will help keep the warranty in effect. Most all equipment manufactures state in the terms of their warranty that annual maintenance must be performed by a qualified technician. Keeping your system maintained will give you assurance that it is operating at peak efficiency and safety.


Q. In the world of plumbing, what is a vent and what does it do?

A. Vents are the pipes (about 12" high) that stick out of your roof. Vents are necessary to vent sewer gasses outside of the home. You can think of a vent pipe like a straw. When you put your thumb over the end of a straw, you can pull liquid up from the cup. What happens when you remove your thumb? The liquid drains out and the straw fills with air. Similarly, when liquid goes down a pipe, air needs to follow it. This air is pulled from the vent pipe. Without a vent pipe, the liquid will try to pull air through the P-traps on plumbing fixtures such as your tub and sink! If this happens, you'll know from the smell! Likewise, without a vent, draining one fixture may cause another fixture in the house to back up!


Q. Why do I have hot water in my toilet?

A. You may have hot water in your toilet because of a bad flapper in the toilet tank or a bad fill valve. When a toilet has a mixing valve (to prevent condensation), a little hot water is added to bring the temperature up. When this system is not functioning correctly, you can get a bowl full of hot water!


Q. What should I do in case of a plumbing emergency like water dripping from my ceiling?

A. The first thing you should remember is that safety comes first. If there are any electrical appliances nearby, turn the electricity off at the main breaker. Then, turn off your main water shut off valve. It's a must to know where this is! (Did you know that a broken pipe or washing machine hose could flood your home with more than ten gallons of water a minute?) If you have a water meter, that is where your main valve should be located. Once the immediate water flow is stopped, call Dial One Hour to have a plumbing technician promptly sent to your home.
