FAQ

Most systems have a lifetime of 10 to 20 years. As your equipment gets older, it's efficiency can decrease dramatically. You may notice that it gets noisier and needs repairs more often. When a unit begins to show it's age, you have two choices. You can overhaul the system or replace it. Because heating and cooling technologies improve over time, a new system designed with newer, more energy-efficient equipment makes sense, especially if your system is 10 or more years old. We can estimate the cost of a new system as well as a payback schedule that will show you how newer technology will pay you back in lower energy usage.

No. Replacing only the outdoor unit will lower the efficiency of the unit. In fact, you can lose up to 15% of the unit's efficiency! Even worse, your system may fail sooner than normal and most manufacturers' warranties will be voided. You should always replace the indoor cooling coil with the outdoor unit.

No, you don't want your air conditioner to be too big. Air conditioners control the comfort level in your home by cooling the air and by removing humidity. An oversized air conditioner will cool your home faster, but it will use more energy and will not remove humidity adequately.

A unit that is too big for your home will have short-run cycles. It may take only a short time to cool the air, but the unit shuts off before enough air blows across the indoor coil, where moisture condenses into water and drains from your system. Too much moisture left in the air can lead to mold and mildew problems.

These short-run cycles also mean your system starts and stops more often, which uses more energy and causes a lot of wear and tear. An air conditioner operates more efficiently during long-run cycles.

The same holds true with heating systems. An oversized furnace will warm the house quicker, but it uses more fuel and causes greater temperature swings in the home.

A matched system is important for a variety of reasons. One is comfort. When all your components are properly sized for your home, you can control exactly how much heating or cooling you need so you can relax. Also, a properly sized matched system enables every component to perform as designed, meaning proper cycle times are maintained, humidity is controlled, and system sound is minimized.

Another reason matched systems are important is efficiency. Most systems people buy are too large for their homes, which uses more energy than is needed for your home. A matched system outlined by a dealer who has completed a load calculation for your home provides just the right amount of heating and cooling you need, so you get the most value for your utility dollar.

At the risk of telling you something you're tired of hearing, replace the air filter in your furnace on a regular basis. Dirty air filters reduce the amount of air flowing through a system and make the furnace work harder to maintain the temperature. How often you change the filter depends on the type of filter you use, if you have pets and the size of your equipment. Please give us a call, and we can give you proper guidance.

Proper air filtration is just as important to your heating and cooling system's health as it is to your family's health. Without proper filtration, dust and dirt can build up on your system, impacting operation and efficiency. A high-efficiency filter will remove more dust, dirt, pollen, mold, and other particles from the air. If you suffer from allergies or other respiratory problems, you should strongly consider a high-efficiency filter. No matter what type of filter you have, make sure you change it regularly.

Yes. Maintaining your system will lower energy and repair costs, prevent breakdowns, and prolong the life of your equipment. Neglecting necessary maintenance ensures a steady decline in air conditioning performance while energy use steadily increases.

Without warranty coverage, a breakdown can mean significant expenses in parts, labor, or both. However, with one of our service agreements, you avoid that unexpected significant expense. While no warranty can guard against every possible problem, we can explain the broad range of protection our service agreements afford.

With a high-efficiency air cleaner, you can remove up to 99% of the pollen and spores that find their way into the home. There is also a great reduction in household dust, dirt, smoke, and other air pollutants. Your indoor air will become cleaner and fresher while reducing the allergens and dust circulating throughout the house. With a whole-house humidifier, you can relieve the irritating discomfort of dry indoor air. The humidifier reduces itchy skin, scratchy throats, static electricity, and damage to your furnishings and woodwork. Since humid air feels warmer than dry air, you do not have to set the thermostat as high to feel the comfort you want. A lower thermostat setting will reduce the costs of your energy bill.

Molds are part of the natural environment. Outdoors and molds play a part in nature by breaking down dead organic matter, such as fallen leaves and dead trees, but mold growth should be avoided indoors. Molds reproduce by means of tiny spores; the spores are invisible to the naked eye and float through outdoor and indoor air. Mold may begin growing indoors when mold spores land on wet surfaces. There are many mold types, and none will grow without water or moisture. Click here to learn more about mold prevention in your home from the EPA.

When humid air passes over chilled cooling coils, water condenses and drips through the coils into a collection pan, from which it continuously drains. Problems with these systems may occur when this water collects and becomes stagnant when it becomes blocked, either on the coils or in the drip pan. The pan will quickly grow mold that can infect your home with dangerous mold spores. Problems also exist when the HVAC ducting contains microscopic mold spores that stay continually present and blow contaminants around the home or office, often caused by mold in other parts of your home.

You can do 3 things to prevent mold growth in your system:

1. Preventative maintenance will ensure that the collection pan under the indoor coil stays clean and clog-free.
2. Install ultraviolet lights next to the cooling coils to kill any mold or bacteria growing on the coils or collection pan.
3. Keep your ductwork clean, and use a high-efficiency filtration system to keep your entire HVAC system clean.

Duct cleaning refers to the cleaning of the various heating and cooling system components of forced air systems, including the supply and returns air ducts and registers, grilles and diffusers, heat exchangers heating and cooling coils, fan motor and fan housing, and the air handling unit housing.

SEER, AFUE, and HSPF are all measures of energy efficiency. Air conditioners may look similar, but their Seasonal Energy Efficiency Rating (SEER) can vary widely. Higher SEER numbers save more money spent on electricity. A 13 SEER air conditioner, the EPA "current minimum standard", uses 23% less energy than a 10 SEER unit (EPA standard up until Jan. 2006). Even though 13 SEER is the minimum efficiency available, we currently offer a line of air conditioners that start at 13 SEER and go all the way up to 21 SEER. Higher SEER air conditioners can significantly reduce your electric bill depending on your average usage.

Heat pumps have SEER ratings like air conditioners and Heating Seasonal Performance Factor (HSPF) ratings for measuring heating efficiency. Higher HSPF ratings mean greater energy savings. The HSPF scale range is 7.5 to 13.0.

Today's new high-efficiency furnaces can save up to 50% in operating costs over a ten-year-old furnace. Many 1990 and earlier model furnaces have Annual Fuel Utilization Efficiency (AFUE) ratings of 65% or less. The minimum AFUE-rated furnace that can be sold in the United States as of May 1, 2013, is 80% in southern states and 90% in northern states.

Our current product offering starts at this minimum AFUE rating and goes all the way to a very efficient 98.3% AFUE rating. Higher AFUE-rated furnaces can significantly reduce your gas bill depending on your average usage.

Cooling

• Upgrade to a high-efficiency air conditioner - Swapping your old, inefficient air conditioning system for a high-efficient one can cut electricity bills by one-third. Consult one of our professional technicians to ensure your system is the right size for your home and you aren't over or under-cooling for your space needs.
• Turn up the temperature - To save electricity during the summer, set the temperature above 75° as every degree below this will add an extra three to five percent to your energy bill.
• Install ceiling fans - Change the direction of airflow on your ceiling fans. In the summer, the blades should operate in a counter-clockwise direction to create a nice, gentle wind.
• Have annual maintenance performed - Having annual maintenance performed on your air conditioner by a licensed technician will help ensure it operates at its peak efficiency. It catches any potential breakdowns before they occur.
• Don't block vents in well-used rooms - Keep your supply and return air vents free of objects like blinds, carpets, or furniture so your air conditioner can operate efficiently and there is even cool air distribution.

Heating

• Upgrade to a high-efficiency furnace - New high-efficiency furnaces use up to 50% less fuel than an older system. It can save you up to 25 percent of your home-heating costs in one year, and within a few years, you'll have recovered the initial cost of replacing/upgrading your furnace. Choosing a model with an energy-efficient motor can save 20 to 50 percent of the energy needed to operate a fan motor continuously. Let us show you the advantages of replacing your old furnace today.
• Have annual maintenance performed - Having annual maintenance performed on your furnace by a licensed technician will help ensure it operates at its peak efficiency. It catches any potential breakdowns before they occur.
• Install a programmable thermostat - A programmable thermostat lets you control your home's temperature when you're away or asleep. For every 1° you lower your thermostat for seven hours per day, you save one percent on your heating bill.
• Don't block vents in well-used rooms - Keep your supply and return air vents free of objects like blinds, carpets, or furniture so your furnace can operate efficiently and there is even heat distribution.
• Install ceiling fans - Change the direction of airflow on your ceiling fans. In the winter, the blades should operate in a clockwise direction, helping to push the warm air from the ceiling down into the room.

The average home spends about $1,900 annually on energy bills. Heating and cooling accounts for as much as half of a home's energy use. The EPA provides important recommendations for energy-efficient equipment, including proper sizing, quality installation and maintenance, and other home improvement considerations to help you get the most out of the heating and cooling products you purchase, save energy, and save as much as 20% annually on your total energy costs.

ENERGY STAR-qualified products prevent greenhouse gas emissions by meeting strict energy efficiency guidelines set by the U.S. Environmental Protection Agency (EPA) and the U.S. Department of Energy (DOE).

Heat pumps are a great solution for your home comfort system because they work to provide both heating and cooling. Heat pumps have SEER ratings like air conditioners and Heating Seasonal Performance Factor (HSPF) ratings for measuring heating efficiency. Higher SEER and HSPF ratings mean greater energy savings.

Heat pumps are a very efficient alternative to electric heat. A heat pump works the same as an air conditioner in the summer, but it runs in reverse in the winter to heat your home. The system will be matched with a backup heating source, most often electric heat, for those cold winter days.

The Earth absorbs almost 50% of all solar energy and remains at a constant temperature of 50°F to 70°F, depending on geographical location. A geothermal unit utilizes this constant temperature for heating and cooling your home. You can save up to 60% on your power bills compared to a traditional system. There is no flame, flue, odors, or loud outdoor equipment. Heating, air conditioning, and hot water can all be attained from a single compact unit.

Variable-speed fans operate on a simple principle: they can spin at different speeds depending on your home's heating and cooling needs. Usually, they operate at lower speeds, delivering a steady, reliable stream of warm or cool air to your home. This helps control humidity levels, utility costs, and system noise. When conditions become more extreme, the fan speed increases so that the system can meet increased demand, guaranteeing that your comfort needs will be met on the hottest days or coldest nights.

2-stage cooling is a method that can better manage your home's cooling while outdoor temperatures are changing. It can also better maximize indoor comfort and energy efficiency. 2-stage cooling systems are typically the most energy-efficient systems out there.

2-stage cooling can be done by having one unit with two compressors, one small and one large. The small one is typically capable of putting out about 50% of the capacity of the larger one. The second way to have 2-stage cooling is to have a single scroll unloading compressor. This compressor can unload its capacity down to about 66% of maximum capacity. Both these methods of getting 2-stage cooling allow the unit to run at a lower stage when the high stage is not needed. By doing this, energy is saved.

2-stage heating has the same principle as 2-stage cooling. It allows the unit to adjust itself based on the amount of heating that is necessary. 2-stage heating is a good way to save on heating costs.

A heat pump system would have two different-sized compressors, a small and a large one. The compressor that is used at a given time would depend upon the need. If only a small amount of heating is necessary, the smaller compressor would be used to save energy. The large compressor would only be used when a large amount of heating was needed.

A 2-stage gas furnace has a modulating gas valve that regulates gas flow depending upon the need.

Normal cooling settings are 75 degrees - 80 degrees. Normal heating settings are 68 degrees - 72 degrees. You should always set your thermostat to the highest possible setting that is comfortable for you in the summer and the lowest comfortable setting in the winter. Setting your thermostat in this way will maximize your energy savings. On average, every 1 degree of temperature change equals about 1% energy savings. For example, changing your thermostat setting from 75 degrees to 76 degrees in the summer could save your cooling costs.

This can occur for many reasons; uneven solar heat load through windows, an undersized system, an improperly balanced or clogged system, or a single system serving a two-story home with no zoning control. Each situation is different, usually requiring an onsite analysis with problem-specific recommendations. Please call to arrange for us to see your home.

Yes. As of January 2010, the refrigerant R-22 (what consumers call Freon®) is no longer allowed to be used in manufacturing new equipment. R-22 has been used as the "standard" refrigerant for many years but has been found to be harmful to our planet by our government. All new air conditioners and heat pumps use R-410A, the more "environmentally sound" refrigerant.

R-22 is still the most commonly used refrigerant in existing air conditioning equipment in residential homes today. However, per the Montreal Protocol, caps have been established to eliminate the production of R-22. In 2004, there was a 35% reduction; in 2010, there was a 65% reduction; in 2015, a 90% reduction; and finally, in 2020 a 99.5% reduction in the production of R-22. This means that during the time of these reductions with high demand, the price of each pound of R-22 refrigerant could potentially skyrocket.

If you are considering replacing your existing air conditioning equipment, most higher efficiency products have already switched to R-410A, the more "environmentally sound" refrigerant.

A difference of 6 decibels (such as between 72 dB and 78 dB) is technically a four-fold increase in compressor sound when rating air conditioners or heat pump units. However, it takes a difference of 10 decibels to double the loudness. It is also noted that it takes approximately 3 decibels for the average human ear to discern any loudness difference.

Great strides have been made in reducing the operating sound level of equipment. We will be happy to show you the difference in sound ratings with our product line.

Yes. Each year, carbon monoxide kills more than 200 Americans and sends nearly 5,000 more to emergency rooms for treatment, reports the U.S. Consumer Product Safety Commission (CPSC). Where does it come from? When carbon-based fuels such as gas, oil, kerosene, or wood burn, they produce gases. Carbon monoxide enters the air when fuel combustion or burning isn't complete. The CPSC advises that carbon monoxide detectors are the only way to alert yourself to the presence of toxic gas in your home. If you wake in the night with a headache, especially if another family member complains of a headache or is difficult to arouse, get out of the house fast and seek medical help. We recommend carbon monoxide detectors be installed in your home!

Propane (LP) gas: You have this type if your gas comes from a tank located outside close to your house. Propane is stored as a liquid under pressure in tanks and cylinders. In most residential applications, propane is used as a vapor. When liquid propane changes into a gas vapor, it expands in volume. This means that even a small leak of liquid propane can result in a much larger quantity of propane vapor, which can be especially dangerous in a confined space. A chemical odorant has been added to propane to give it a distinct smell. Learn to identify this odor. Propane gas is heavier than air, so it will sink to the floor and spread. To check for the presence of propane, carefully smell all over a room, especially in low spots.
If you smell propane (LP) gas:

• Exit your home immediately.
• Propane gas can ignite easily. Do not light a match, start an engine, use a cell phone, or do anything that may create a spark.
• From a safe area, contact your propane supplier and call 911.
• If you can, shut the propane gas supply off at the tank.
• Stay away from your home until you've been told that it is safe to return.

Natural gas: You have this type if you have a gas meter and pay a natural gas supplier or utility. A chemical odorant has been added to natural gas to give it a distinct smell. Learn to identify this odor.
If you smell natural gas:

• Exit your home immediately.
• Do not light a match, start an engine, use a cell phone, or do anything that may create a spark.
• From a safe area, contact your gas company or call 911.
• If you are able, turn the gas off at the meter.
• Stay away from your home until you've been told that it is safe to return
