  • Why should I have regular maintenance?

    Your heating and cooling systems work hard to perform their functions for your home or office everyday. Without consistent care and maintenance, the constant stopping, starting and continual operation can wear down any machine. This problem can be prevented by performing regular maintenance, which can maximize the lifecycle of your heating or cooling unit and safeguard against many common appliance failures. Preventive maintenance checkups performed routinely can uncover leaks, rust, rot, soot, frayed wires and corroded electrical contacts that may not initially be noticed. You should have maintenance done regularly to ensure maximum efficiency and prevent possible problems that may occur in the near future.

  • What type of filter should I use?

    Standard filters work to keep your system and its ductwork clean, but they don't fully improve indoor air quality. To improve the indoor air quality, a media filter is recommended. A media filter rests between the main return duct and the blower cabinet and will improve dust and particle removal up to seven times that of a standard filter. Upgrading to a pleated media filter will remove everything from pesticide dust to airborne viruses from the filtered air. When choosing a filter, make sure that you chose one that matches your blower's capacity and power. Houston Smart Air Cooling & Heating Inc. recommends that disposable filters should be replaced at least once a month for optimum efficiency and filtration. Washable filters should also be cleaned once a month.

  • What does HVAC stand for?

    HVAC (pronounced h-vack or spelled out) stands for Heating, Ventilating and Air Conditioning. The three functions of heating, ventilating, and air-conditioning are closely interrelated. They all provide thermal comfort, clean indoor air quality, and reasonable installation, operation, and maintenance costs. HVAC systems can improve ventilation, reduce air infiltration, and maintain pressure relationships between spaces. Your Smart Air HVAC contractor will provide you with exceptional HVAC service in regards to HVAC repair and HVAC replacement.

  • What are SEER and EER?

    Since 2006, all residential air conditioners sold in the United States are required to have at least a 13 SEER. SEER is the abbreviation for Seasonal Energy Efficiency Ratio, which is a U.S. government standard energy rating that reflects the overall system efficiency of your cooling system. It measures the cooling output during a typical cooling-season divided by the total electric energy input during the same period. An EER is the abbreviation for Energy Efficiency Ratio. It doesn’t consider the time of year, but rather the system's energy efficiency at the peak operating use. Both ratings should be considered in choosing cooling products since they measure different objectives. The rating is a ratio of the cooling output divided by the power consumption and measures the cooling performance of the system. The Federal government developed an ENERGY STAR program for high efficiency central air conditioning systems that must have a SEER of at least 14 in order to qualify.

  • What is the average life expectancy of a system?

    Most systems can last anywhere between 10 and 20 years. As your system gets older, it loses its efficiency and requires more repairs. Once your system gets to the point where repairs can only help so much, it may be time to replace it. Since heating and cooling systems improve yearly, it makes the most sense to replace your old system with a new one that will be more efficient and can save you more money.

    How should I know what system best fits my needs? Some people may think that the larger the heating or cooling system the better, but this is not true in a lot of circumstances. A large system may cool your home quicker, but it will use more energy and will cause you to spend more money. The ductwork in your home also needs to be able to support the system that you chose for your home. Systems too large for your home can create problems. To avoid these problems, a proper system should be chosen to fit your home.

  • How does the Clean Air Act impact HVAC?

    The Clean Air Act encourages the development of ozone-friendly substitutes for chemicals in the HVAC industry that contain ozone destroying chlorine, which are called hydrochlorofluorocarbons (HCFCs). The law is designed to control and decrease air pollution. Refrigerants are what make air conditioning possible. They are liquid agents that cool and humidify the air indoors. For many years, a refrigerant called R-22 was the most commonly used refrigerant in heat pumps and AC condensing units to heat and cool homes. The R-22 chemical refrigerant was prohibited in 2010 because of the new policy. R-22 was then replaced by a refrigerant called R-410A because of its ozone-friendly properties. Nowadays, the highest efficiency cooling systems use the R-410A refrigerant to abide by the recent policy.

  • What is a heat-pump?

    A heat-pump is a HVAC compressor that cools outside and heats inside. It provides heat energy from a source of heat to a certain destination. They are designed to move thermal energy in the opposite direction of heat flow by applying heat from cold spaces and delivering it to warmer ones. It is cheaper to operate than a resistive heating circuit alone. It will work efficiently until the temperature significantly drops, then the restive heat is more effective. The heat-pump will still work at colder temperatures, but the heat produced is very little.
