Is sound an issue for heating and air conditioning?

Yes. Noisy heating and cooling equipmentincrease 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 San Antonio home. The sound level of an air conditioner or heat pump depends on a number of things, such as the , and the degree to which the compressor is insulated can increase the amount of noise it makes.

Although most heating and cooling systems built today are quieter than ever before, it's a good idea to compare sound ratings when assessing 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 noise is a typically sign of an under-sized duct design. It may have to do with 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 be attributed to a number of ventilation and air quality problems, including excessive noise.

When changing the outdoor system, 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 speciallycreated to work with a matched indoor unit for ideal efficiency and performance. The effect of this matched equipment is a synchronized, top-performance team that ensures dependability and efficiency. Air conditioner and heat pump outdoor units may ”run” with indoor units other than those for which they have been speciallyintended; 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 comprise the latest design advances.

Higher Cooling And Heating Efficiency: The cooling and/or heating efficiency ratings that are presented 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, efficiency will be lacking from what it was designed to be, and your savings will be not as much as with a matched system.

Equipment Age: If an air conditioner or heat pump is 10 years old or more and is ready for replacement, the indoor unit is likely just as old and has been subjected to the same amount of degradation. Changing 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. Substituting the indoor unit together with 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 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 is it important to have regular maintenance on my home comfort system?

You probably wouldn't purchase a brand-new car and assume to not ever have to inflate the tires, change the oil and examine any abnormal 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 essential to have routine maintenance of your home comfort system by a qualified technician. If not maintained properly on a routine basis, even the best heating and air conditioning equipment could experience complications and become less 'fuel' efficient over time.

Why is my AC system freezing up?

There are manypossibilities 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 identify or handle themself.

Low refrigerant: On occasion, freezing up is initiated 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 length of time your system has been installed and the nature and location of the leak will determine 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 remedy the problem.

Defective blower motor or relay: A blower motor operating at the wrong 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 discover that your system was freezing due to a dirty air filter, after replacing or cleaning the filter, you can hasten 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, turn the system settings back to normal. If the system refreezes, contact San Antonio Air Service Experts Heating & Air Conditioning in San Antonio to solve the problem.

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

Zoning Systems split your home’s duct work into different 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. A different example of areas that may 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. Contemporary families 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 maintain each area of your house at the perfect temperature for you and each family member.

San Antonio Air Service Experts Heating & Air Conditioning provides free estimates and a complimentary consultation on Zoning Systems, call 210-570-9705 today if you think a new Zoning System might be right for you.

Can indoor air be hazardous to your health?

No doubt about it. 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) important for homeowners to know about. 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 know that I have carbon monoxide in my home?

The best method of detection is to use a carbon monoxide detector in a central location. 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 210-570-9705 for a complimentary consultation about purchasing a carbon monoxide detector.

How can I eliminate indoor odors?

You may have tried to eliminate 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 integrating 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 San Antonio Air 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?

A great way to choose the correct humidifier is by having a home health report performed by San Antonio Air Service Experts. Every house 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, San Antonio Air 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 brands 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 commissioned 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 caught 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 San Antonio Air 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 type you choose and the size of your house, 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.
