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.

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 monthly filter replacements. Your Air Texas Experts service or installation technician will recommend the ideal filters and replacement schedules for your unit(s).

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 Horizon Services to check out your system whenever you notice anything out of the ordinary.

Chiller systems, which are a part of an HVAC system, help regulate temperatures in buildings by removing heat. They use liquid refrigerant to generate cold water for air conditioning. Here’s a breakdown of the basic cooling cycle of a chiller system:

During the cooling cycle, the refrigerant will change to a gas within the evaporator, which absorbs heat. Next, the gas refrigerant will be compressed by either a compressor or generator. After that, it will go through the condenser, which will remove unwanted heat energy. As it loses heat, the refrigerant will return to a liquid. However, it’ll be much cooler than it was at the beginning of the cycle. The refrigerant will then go back through the system again, continuing the cooling cycle.

ike any other component in your HVAC system, the chiller requires regular maintenance to continue operating at peak performance. For instance, on a weekly or monthly basis, the temperature, pressure, fluid levels, and flow rates should be checked. Every few years, the tubes will should also be cleared of possible contaminants, like mineral buildup, lime scale, and algae. Over time, you may also need to replace pump systems, seal water leaks, and repair the compressor.
