Here are some of the most common questions we hear from our customers.

The SEER (seasonal energy efficiency ratio) is how the efficiency of your heating and cooling equipment is measured. The SEER is the amount of cooling your system will deliver per dollar spent on electricity, as compared to other systems. For example, a 3-ton unit may have a SEER efficiency rating of 13, 14, or 15. The higher the SEER the more efficient the system will be. The SEER rating of any given unit can range anywhere from 13 to 21.

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.

We install and repair all makes and models of HVAC equipment. You can call any qualified company to warranty your equipment.

A traditional tank water heater stores and heats water continuously. A tankless heater works on demand. It gives you hot water when you turn on the tap but stops working when you don’t need it.

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, we are 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. Lorenz Plumbing Heating & Air Conditioning 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.

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.
