Frequently Asked Questions

The most important part of HVAC maintenance aspect is maintaining unrestricted air flows. Dust, dirt, and debris are an HVAC system’s worst enemies. Whether it’s an indoor or outdoor unit, you must keep all filters clean and heat exchangers and coils free of restrictions.

We recommend that your heating and cooling system be checked and serviced twice a year; ideally a spring and autumn tune-up. Also we recommend that you change your filter regularly, depending on the type of filter you have. This alone can eliminate many of the most common problems that need fixing and can significantly reduce the likelihood of a serious breakdown.

Locate the label on the outer surface 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 based on the model. Warranty terms and conditions change by manufacturer and the installing company.

Regular filter replacement helps your heating and cooling system operate at peak levels and improves indoor air quality. It is important to change filters regularly to ensure proper air flow and to keep your home free from dust, allergens and germs. Depending on the type of filter you have, you may require weekly or monthly filter replacements. Your service or installation technician will recommend the ideal filters and replacement schedules for your unit(s).

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.

Is it making strange noises? Is it cooling or heating all areas of your home sufficiently? Has it been taking longer to cool down or heat up? Have your utility bills been rising for no apparent reason? Any of these are signs that you may have a problem that needs service. In most cases, the longer you delay, the worse any underlying problems will get. So be sure to contact Smittys to check out your system whenever you notice anything out of the ordinary.

There are several things that can cause your system to ice up.

Making sure the filter is clean or replaced and making sure the airflow is not restricted are about the only things you can check or handle yourself.

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. Contact Smittys 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 icing. 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 can contact Smittys to correct the problem.

Should you find that your system was icing due to a dirty filter, after replacing or cleaning the filter, you can speed up the thawing process by turning the system off and turning on 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 re-ices, contact Smittys to diagnose and correct the problem.

A few quick tips:

• Clean and replace your filters frequently.
• Your system will heat and cool more evenly when the fan is in the ‘Auto’ position.

You may have tried to cover up 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 contributes to unpleasant odors. Moisture condensation on walls windows and stagnate air are signs of poor ventilation. A qualified Smittys Air 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.

Every person and every home entails a different comfort need. The threshold of irritants 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. Smittys Air can help you decide which indoor air improvement products are right for you.

According to studies created 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 a vacuum. Some filtration devices include UV light units, air filters, energy recovery ventilators (ERVs), heat recovery ventilators (HRVs) and electronic air cleaners. Smittys Air can provide information about which indoor air improvement devices are right for you.

Temperature settings depend on the time of year and your personal preferences. In the summer, the average temperature setting is 75°-80°. In the winter 68°-72° is the norm. Remember, when leaving your house; try to avoid drastic temperature changes. Do not set your temperature back more than 5°; this will cause your unit to work harder to achieve the desired temperature setting.

With energy costs soaring, there are a variety of steps you can take to cut the expenses of cooling your home.

Cooling and heating equipment use more energy than any other appliance. This inevitably shows up every month on the energy bill, but it’s important to remember that energy costs can be controlled.

High Efficiency:
If you are in the market for a new home comfort system, consider purchasing a high-efficiency system. They can help reduce your energy costs as well as conserve our natural resources. When selecting a new home comfort system, pay close attention to the SEER rating of the air conditioner. The higher the SEER, the higher the savings.

Maintenance:
One step to control energy costs is to schedule annual maintenance checks to make sure your unit is running properly and efficiently. Most home comfort systems require very little owner maintenance. However, operating dirty heating or cooling equipment can result in unnecessary loss of efficiency and can damage the unit. You play a vital role in making sure your system continues to operate at peak performance.

Smittys Air can help you select the best solutions for conserving energy dollars in your home.
