Frequently Asked HVAC Questions in St. Louis, MO and Surrounding Areas

Each split system cooling unit has a nominal SEER rating. This rating can be increased with the upgrade of the same series indoor unit. The SEER rating of a system is based on the combination of equipment installed in the home. The outdoor equipment (heat pump or air conditioner), as well as the indoor equipment (evaporator coil and furnace, or air handler), play a vital role in the total rating.

Your heating and cooling systems work incredibly hard to perform their functions for your home everyday. The constant stopping, starting and continual operation can wear down any machine if the proper care and maintenance is delayed. However, by performing regular maintenance, you can maximize the lifecycle of your heating or cooling unit and guard against many common equipment failures. Preventive maintenance inspections performed on a regular basis can uncover leaks, rust, rot, soot, frayed wires and corroded electrical contacts. You should have maintenance completed on your system regularly to ensure maximum efficiency and prevent possible problems that may occur in the near future.

Heat pumps and air conditioners require a professional tune-up twice a year; in the spring and fall. Inspections on boiler and furnace systems should include ductwork, pipes, dampers, valves, the chimney, registers, radiators, pumps, blowers, fuel lines, oil tank and every part of the actual furnace and boiler. Meanwhile, heat pump and air conditioning unit inspections should also include inspections of the fan, compressor, indoor coils, outdoor coils, and refrigerant lines.

Since they are electronic, programmable thermostats are more accurate and efficient than thermostats that contain mercury. With programmable thermostats you can control the temperature in your home at different times of day without ever touching your thermostat. Because everything is automatic, you will never forget to change the setting on your own.

Standard filters work to keep your system and its ductwork clean, but they don’t really improve indoor air quality. To do that you need a media air cleaner. The 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. However, upgrading to a pleated media filter will remove everything from dust to airborne viruses from the filtered air. Always choose a filter that matches your blower’s capacity. For optimal efficiency and filtration, we recommend that you replace your disposable filters at least once a month. If you have washable filters, they should be cleaned once a month.

Filters for your Trane unit are made from higher-quality materials than those of the disposable filters found in retail stores. For that reason, replacement Trane filters can only be purchased through a Trane dealer. However, keep in mind that some Trane filters are reusable, and can be washed by hand in cold water.

As a Trane dealer, Indoor Comfort Team is the best resource for identifying and supplying the correct, current parts for your system, as well as pricing and availability.

There are many factors that affect the sizing and specifications of your system, including square footage, insulation, window surface and configuration, geographic location of your home, duct sizing and arrangement, and many others. Indoor Comfort Team can perform an in-home load analysis to determine which equipment combinations will perfectly suit your home and your family’s needs. Depending upon the construction of your home, one (1) ton of air conditioning can cool anywhere from 300 to 800 square feet of home. The only way to ensure the size of the system you purchase will be large enough to heat or cool your home, but not any larger than you need, is to have your home’s individual heating and cooling needs evaluated by a licensed professional.

Under the standard factory warranty, Trane covers parts that fail during the warranty period due to defect in the part. The warranty does not cover labor. A warranty certificate was included with your homeowner information packet, and is specific to the model numbers, serial numbers and installation dates of your products.  All Trane equipment that we install is registered with Trane Corporation to ensure your 10 year parts warranty.  If you cannot find your warranty certificate, Indoor Comfort Team will also be able to provide you with that information. With an Indoor Comfort Team Total Comfort Plan, you’ll have a ten year parts and labor warranty on your Trane equipment.

Dependable Trane products are among the longest lasting heating and cooling products available. For your specific equipment, there are many variables that affect life expectancy, including, of course, the regularity of routine maintenance.
