Frequently Asked Questions

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

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

Is sound an issue for heating and air conditioning?

Yes. Loud heating and cooling equipment contribute to sound pollution.While no cost savings are tied to less sound in your home, the sound rating of a cooling system can have a serious effect on comfort and enjoyment of your Jackson home. The sound level of an air conditioner or heat pump depends on a number of things, such as how old and who manufactured the equipment, and the insulation of the compressor can increase the amount of noise it makes.

Although most heating and cooling systems made today are quieter now more than ever, it's a good  thought to compare sound ratings when evaluating a new air conditioner or heat pump, particularly if the equipment location is near bedrooms or living rooms.

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 built for. Have a qualified company analyze your home's ventilation system for proper design and recommend adjustments. Improper duct work layout can be attributed to a variety of ventilation and air quality problems, including: 

  1. excessive noise
  2. higher energy usage
  3. lowered life expectancy of the system
  4. uneven heating & cooling throughout your home
  5. damaged compressor in cooling season
  6. overheated unit in the cooler months
In addition, if your ductwork is incorrectly sized you may have other problems, such as leaky ducts and poor layout that impacts airflow. In humid states this can encourage mold growth within your ductwork.

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

The answer is, probably so. Here's why.

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

Design Advances: Over time, indoor blower coil units have undergone numerous design advances — especially in the areas of air handling performance, filtering efficiency and operating sound levels. An up-to-date outdoor unit will also incorporate 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 give you improved efficiency compared to the old system, but efficiency will suffer from what 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. Substituting both units means you won't have to replace the indoor unit in just a short time… you'll have many years of efficient service with both units.

New Warranty: A new system also provides you a new product warranty. Substituting 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, changing only the outdoor air conditioner or heat pump may appear to be a savings. 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 charge makes available more value for our customers because nothing is excluded, the pricing is up-front, and it does not get modified. Regardless of the cost of parts or how much time it takes to complete the repairs, the price will not change. This reason is one of many why Comfortech Service Experts Heating & Air Conditioning is the most trusted name in Jackson.

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 not ever have to inflate the tires, change the oil and examine any atypical noises. Your home comfort system is similar to your car’s engine; it’s a mechanical device with a motor, electrical components... and even fuel. So it is critical to have routine maintenance of your home comfort system by a qualified technician. If not properly and routinely maintained, even the best heating and air conditioning equipment could have difficulties and become less 'fuel' efficient over time.

Why is my AC system freezing up?

There are several things that can trigger your HVAC system to freeze up; almost all of them usually need to be corrected by a professional technician. Determining the air filter is clean or replaced and making sure the airflow is not restricted are about the only tasks a homeowner should safely investigate or handle themself.

Low refrigerant: Sometimes, freezing up originates with 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 length of time your system has been installed and the nature and location of the leak govern the decision whether to have the system repaired or replaced.

Dirty evaporator coil: As time passes, the evaporator coil will become dirty. When this happens, the results are similar to those of having a dirty filter. Progressively 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 fix 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 sporadic, 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 learn 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 Comfortech Service Experts Heating & Air Conditioning in Jackson 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, providing for independent temperature control in distinct areas that require specific temperature conditioning.

For example, a cathedral-style room with large bay windows may retain too much heat in the summer and feel too cold in the winter. A Zoning System will deliver more conditioned air to this large, sun-drenched area to help compensate for the heat gained or lost through the windows. An additional example of areas that could 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. Families today have different lifestyles and comfort needs. You could 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 keep each area of your house at the perfect temperature for you and each family member.

Comfortech Service Experts Heating & Air Conditioning provides free estimates and a complimentary consultation on Zoning Systems, call 601-852-3105 today if you think a new Zoning System is what your family needs.

When should I install a Zoning System?

If you are replacing your Jackson area home air conditioner, furnace or heat pump, it is an excellent time to also install a new zoning system to fix hot and cold spots or special temperature preferences in the home. When your new comfort equipment is coordinated by a zoning system, your family benefits from precision temperature control in each zone.

Zoning is also a great idea for new homes since the system can be installed during construction. If you are purchasing 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.

Are all HVAC air filters the same?

No, HVAC air filters vary in quality and size, and some have features that others don't. Usually we recommend installing the filter your HVAC manufacturer recommends pairing up with your installed system, though you might be tempted to try a different filter type for convenience or to remove extra contaminants from your residence.

All filters have MERV ratings, which range from 1-20. MERV means "minimum efficiency reporting value". A higher MERV rating equates to fewer contaiminants pass through, and it blocks finer particulates. This seems obviously good, and it can be, but a filter that catches finer dust and dirt will also clog up more often, and pressure on your system will increase. If your system has not been engineered to operate with this kind of filter, it can actually reduce your airflow within your residence, impacting your comfort and energy expenses. So what should you know before you buy? Unless you're a hospital, you simply don't need a MERV rating above 13. Fun fact, most residential units are specifically designed to work with a filter with a MERV rating below 13, and most often you will discover that quality systems have been made to work with a MERV rating of 8 or 11. All filters with a MERV rating of five should eliminate most of the everyday nuisances people care about such as pollen, pet dander, and dust. While some filters claim to be able to capture mold spores, we recommend having a professional remove any mold from your home you find, instead of trying to hide the issue with a finer filter.

Frequently the packaging shows how often your filter ought to be replaced. There are one-month filters and there are 3-month filters. There are also filters that are two dimensional, flat screens, and you have some that are built accordian style with supporting wire. In our experience, the accordian style filters hold up better, and are worth the extra pennies.

You could also consider washable filters, also known as reusable filters. Some homeowners like the environmentally friendly aspect of it, because they don't want to add to a wasteyard, and others consider it more convenient to simply slide out the filter and wash it off rather than making a run to the local hardware store for a filter of the proper size. These filters are often designed to endure several years and will save you cash over those years, though they cost more initially. However, washable filters do need to be dried out all the way before inserting it back to stop mold growth in your ductwork. In addition, most washable filters usually have a MERV rating between 1 and 4, and they lose their efficiency over the years. Some washable filters have been built with updated technology, such as electrostatic air filters, that are meant to basically improve the MERV rating.

And lastly, filters are built with different materials. Fiberglass filters are what is bought most often, and are the disposable type. Polyester and pleated filters are known to catch more debris, but also lessen the airflow in your home. And there are high efficiency particulate arrestance filters, or you might recognize the acronym HEPA. While you may be tempted to use a HEPA filter, keep in mind that's like putting a MERV 16 filter in your HVAC system and it's very unlikely that your system was constructed to handle that kind of resistance.

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 contribute to 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. As well, 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 like a smoke alarm. It monitors the air for carbon monoxide and emits an alarm if a specific level is detected. Ideally, you should have at least one detector adjacent to every living area, centrally located, or on each floor in your home. Carbon monoxide detectors are best when used in combination with a maintenance plan. Call 601-852-3105 for additional details 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 is also a cause of unpleasant odors. Moisture condensation on walls windows and stagnate air are signs of poor ventilation. A qualified Comfortech Service Experts technician can inspect your home comfort system to determine if this is an issue that should be addressed. The technician can also inform you how to solve the ventilation system’s ability to correctly 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 Comfortech Service Experts. Every home is different, and every family is different. So, every humidification need is also different. There are a few factors to evaluate when purchasing a humidifier for your home, Comfortech Service Experts can help you understand and consider these issues.

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 suggestions for knowing which type of humidifier will best suit you and your family’s comfort needs.

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

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 vacuuming. 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 Comfortech Service Experts will provide the information about which indoor air improvement devices are right for you.

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 liquid used is enough to raise the humidity to the proper level, but not enough to notice a difference on your water bill.
