Frequently Asked Questions

Frequently Asked Questions

How do I know if I have an existing warranty on my furnace, air conditioner or HVAC system?

Look atthe label on the outside of the equipment for a manufacture date. If the equipment is less than five years old it may have a warranty, but also may not depending on the manufacturer. Warranty terms and conditions vary by manufacturer and the installing company. Service Experts Heating & Air Conditioning can determine the warranty status of your heating and cooling system via System Inspection. We also offer a Platinum PLUSTM Protection Plan for residential heating and air conditioning systems, regardless of the equipment age or manufacturer warranty status.



Is sound an issue for heating and air conditioning?

Yes. Loud heating and cooling equipment contribute to sound pollution. Although no financial savings are tied to lower sound levels, the sound rating of a cooling system can have a considerable effect on comfort and enjoyment of your home. The sound level of an air conditioner or heat pump depends on a variety of factors, such as the age and make of the unit, and whether the compressor is insulated or not can contribute to the amount of noise it makes.

Although most heating and cooling systems manufactured today are quieter than ever before, it's a goodidea to compare sound ratings when shopping for a new air conditioner or heat pump, particularly if the equipment location is near bedrooms or living rooms.



What is a Precision Tune-up and how much does it cost?

As well as the visual check provided with our System Inspection, a Precision Tune-up also includes a complete maintenance cleaning and lubrication of the heating or air conditioning equipment components. Find out more here about Service Experts Heating & Air Conditioning’s Precision Tune-up steps . The cost of a tune-up varies by season, and may generally range from $69 to $159. Printable coupons with seasonal discounts on tune-ups are also usually available on our Coupons page.



What's causing my duct work to pop when the furnace starts or stops?

A popping sound is a typically sign of an under-sized duct design. It may be caused by greater air flow than the duct work is able to manage. Have a qualified company analyze your home’s ventilation system for proper design and recommend adjustments. Improper duct work layout can cause a number of ventilation and air quality problems, including excessive noise.



When replacing the outdoor equipment, should the indoor unit also be replaced?

The answer is, most likely yes. Here's why.

Matched System Design: All air conditioner and heat pump outdoor units are specificallycreated to work with a matched indoor unit for peak efficiency and performance. The result of this matched equipment is a coordinated, top-performance team that ensures dependability and efficiency. Air conditioner and heat pump outdoor units may "work" with indoor units other than those for which they have been specificallyconstructed; however, the consequence would be a definite compromise in system performance.

Design Advances: Through the years, indoor blower coil units have undergone numerous design advances — especially in the areas of air handling performance, filtering efficiency and operating sound levels. A new outdoor unit will also include the latest design advances.

Higher Cooling And Heating Efficiency: The cooling and/or heating efficiency ratings that are advertised for an air conditioner or heat pump are based on their performance as matched systems. While changing only the outdoor unit may effect in improved efficiency compared to the old system, it will not be as efficient as it was designed to be, and your savings will be lower than with a matched system.

Equipment Age: If an air conditioner or heat pump is 10 years old or more and needs to be replaced, the indoor unit is likely just as old and has been subjected to the same amount of wear and tear. Replacing both units means you won't have to replacethe indoor unit in a short time period… you'll have more years of efficient service out of both units.

New Warranty: A new unit also gives you a new product warranty. Replacing the indoor unit at the same time as the outdoor unit results in peace of mind, knowing that the new warranty covers the entire system for the same period of time.

A Bargain: At first glance, replacing only the outdoor air conditioner or heat pump may appear to be a bargain. But, when you consider the lower cooling and heating efficiencies, decreased reliability and high cost of ownership that results, it's not such a bargain. Replacing an entire system may cost more, but you benefit from efficiency, reliability and comfort for years into the future.



Why don't you charge by the hour?

Similar to a value menu at a local restaurant, charging a flat rate cost instead of an hourly costprovides more value for our customers because everything is included, the pricing is up-front, and it does not adjust. Regardless of the cost of parts or amount of time it takes to make the repairs, the price will not change. This is just one reason why Service Experts Heating & Air Conditioning is the most trusted name around.



Why is it important to have regular maintenance on my home comfort system?

You probably wouldn't buy a brand-new car and expect to never have to put air in the tires, change the oil and check out any abnormal noises. Your home comfort system is like your car’s engine, it’s a mechanical device with a motor, electrical components... and even fuel. So it is important to have routine maintenance of your home comfort system by a qualified technician. If not maintained properly and routinely, even the best heating and air conditioning equipment could cause problems and become less 'fuel' efficient over time.



Why is my AC system freezing up?

There are severalthings that can cause your HVAC system to freeze up; most of them usually need to be corrected by a professional technician. Making sure the air filter is clean or replaced and confirming the airflow is not restricted are about the only things a homeowner should safely check or handle themself.

Low refrigerant: In some cases, freezing up is caused by a leak in the refrigerant lines. Weak solder joints, friction from piping rubbing or vibrating against an object, leaking valves or loose fittings can cause leaks. The age of the system and the nature and location of the leak are the determining factors on whether to have the system repaired or replaced.

Dirty evaporator coil: Over time, the evaporator coil will become dirty. When this happens, the results are similar to those of having a dirty filter. Gradually you will lose airflow, slowly enough that you probably would not realize it until it freezes up or is not cooling adequately. You will need to contact your local Service Experts sales and service center to correct the problem.

Defective blower motor or relay: A blower motor not running at the proper speed or not running at all can cause freezing. It can also be intermittent, starting at full speed and slowing down after it heats up. Or a relay could cause it to start one time and not the next. In either case, you will need to contact your local Service Experts sales and service center to correct the problem.

Should you find that your system was freezing due to a dirty air filter, after replacing or cleaning the filter, you can speed up the thawing process by turning the system off and then turning on only the fan. If you have a heat pump system, you can try turning the system to heating mode until the ice has melted. After the ice has melted, switch the system settings back to normal. If the system refreezes, contact Service Experts Heating & Air Conditioning in to correct the problem.



What is a Zoning System for a heating and air conditioning system?

Zoning Systems divide your home’s duct work into separate comfort areas, allowing for independent temperature control in distinct areas that need specific temperature conditioning.

For example, a large living room with large bay windows may stay too hot in the summer and feel too cold in the winter. A Zoning System will send more conditioned air to this large, sun-drenched area to help make up for the heat gained or lost through the windows. Another example of areas that might benefit from Zoning might be a nursery, home theater or music studio, where different temperatures may be needed in each room for the comfort and enjoyment of the people occupying these rooms. Today's families have different lifestyles and comfort needs. Maybe you have a home office that needs extra conditioning during the day and none at night. Or you only use the upstairs or back bedrooms when guests visit. Whatever your needs, a zoning system can maintain each area of your house at the perfect temperature for you and each family member.

Service Experts Heating & Air Conditioning provides free estimates and a complimentary consultation on Zoning Systems, call 866-397-3787 today if you think a new Zoning System might be right for you.



When should I install a Zoning System?

If you are replacing your area home air conditioner, furnace or heat pump, it is an excellent time to also install a new zoning system to address hot and cold spots or special temperature needs in the home. When your new comfort equipment is matched with a zoning system, you will gainprecise temperature control in each zone.

Zoning is also excellent for new homes since the system can be installed during construction. If you are buying a new home, check with your builder about a zoning system. It could make the difference between just enjoying your new house and being truly comfortable in it.

Can indoor air be hazardous to your health?

Yes, with a capital Y.E.S. Exposure to air pollutants can be up to 100 times higher indoors than outdoors. The American Lung Association estimates that most people spend 90 percent of their time indoors, making indoor air quality (IAQ) extremely important. Many common household items contribute to poor indoor air quality. Compounds found in carpeting, furniture, upholstery and drapery fabric constantly emit fumes. Other sources of pollutants can include cleaning agents, paints and personal care products. The tight construction of today's homes also contributes significantly to poor IAQ. Things like weather stripping and storm doors are designed to save on energy costs. However, they also prevent proper ventilation by keeping indoor air in and outdoor air out. The result can be a buildup of contaminants within the home.

Poor IAQ can be a direct or indirect cause of several health problems. Medical groups report that as many as half of all illnesses are caused or aggravated by indoor air pollution. Pollutants within the home can cause homeowners to suffer from flu-like symptoms such as headaches, nausea and respiratory irritation. Additionally, two existing health problems that can be helped by improving indoor air quality are allergies and asthma. By removing airborne dust particles, the amount of exposure the respiratory system has to them is reduced. Proper ventilation also plays an important role in improving indoor air quality, helping to reduce the concentration of pollutants inside the home.



How can I detect carbon monoxide in my home?

The best method of detection is to use a carbon monoxide detector in your home. A carbon monoxide detector is a device very similar to a smoke alarm. It monitors the air for carbon monoxide and sounds an alarm if a specific level is detected. Ideally, you should have one detector adjacent to every living area, centrally located, or on each floor in your home. Carbon monoxide detectors are most effective when used in combination with preventive maintenance. Call 866-397-3787 for more information about purchasing a carbon monoxide detector.



How can I eliminate indoor odors?

You may have tried to get rid of indoor odors by spraying air fresheners or lighting candles. Unfortunately, these tactics only mask the odors, they don't get rid of them. These remedies may in fact negatively affect indoor air quality from chemicals that cause allergic reactions or eye irritation for homeowners.

Bacteria, dust mites, animal dander, cat saliva and mold may also be roots of your home's odor problem. One method to purify the air is using germicidal (UV) lights in your home, which helps kill odors and inhibit the growth of biological contaminants, sterilizing surfaces in the HVAC system. They also purify the air, preventing the growth of contaminants. The UV lights are installed to work with your home comfort system.

Sometimes poor ventilation contributes to unpleasant odors. Moisture condensation on walls windows and stuffy air are signs of poor ventilation. A qualified Service Experts technician can inspect your home comfort system to determine if this is indeed the problem. The technician can also inform you how you could increase the ventilation system’s ability to properly circulate and ventilate indoor air.



How do I choose the right humidifier?

The best way to choose the correct humidifier is by having a home health report performed by Service Experts. Every home is different, and every family is different. So, every humidification need is also different. There are a couple factors you should take into consideration when purchasing a humidifier for your home, Service Experts can help you understand and consider these criteria.

Consider size. A humidifier's capacity, or the amount of moisture it can dispense in a given time, should match your particular household's needs. The capacity is measured as gallons per day of operation. One method that is used to determine the correct-sized humidifier for your home is by multiplying the total floor area in by the ceiling height. We can provide you with this information and additional ways you can determine which type of humidifier will best suit you and your family’s comfort needs.

Consider cost. Consider not only the purchase price of the humidifier, but also operating and maintenance costs. Some models consume more energy than others, so choosing a model that is right for your home and budget is extremely important.



How do I know which indoor air quality product is right for me?

Every person and every home entails a different comfort need. The threshold of irritancy and triggers that affect people’s health and comfort combine to determine the proper solutions. High threshold levels may require simple solutions like a better air filter. Low threshold levels may require an air purification system for the reduction of triggers and irritants. With a Home Health Report Card, Service Experts can help you decide which indoor air improvement products are right for you.



How healthy is my indoor air?

According to studies conducted by the U.S. Environmental Protection Agency, exposure to air pollutants indoors can be 100 times higher than outdoors. Frequent dusting and vacuuming can help reduce the amount of dust and dust mites present in your home. However, not all airborne particles can be eliminated. Filtration devices can help eliminate particles that are too small to be captured by a vacuum. Some filtration devices include UV light units, air filters, energy recovery ventilators (ERVs), heat recovery ventilators (HRVs) and electronic air cleaners. A Home Health Report Card from Service Experts can help you decide which indoor air improvement products are right for you. To receive a Home Health Report Card and personal air quality consultation Service Experts at 866-397-3787.



How much water does a humidifier use?

Depending on the model you choose and the size of your indoor area, a humidifier may use from 1.5 to 12 gallons per day when the furnace is operating. The amount of water used is enough to raise the humidity to your desired level, but not enough to notice a difference on your water bill.
