If your heating and air conditioning unit malfunctions on a regular basis or has other issues, such as not providing enough heat or cool air, it may be time to purchase a new unit. However, it is possible that your heating and air conditioning system has not been properly installed.

When a unit is improperly installed, your costs will tend to be up to 30% higher. The contractors from an air conditioning and heating repair service will be able to check your unit to determine whether or not it was installed properly. At this time, they may also check your gas pipe installation as part of determining what repairs might be needed.

Your heating and air conditioning repair service will let you know if you need a new system. They will likely recommend a high-efficiency heating and air conditioning unit that can be operated with a programmable thermostat. Best brand heating and cooling systems like these will last between 12-to-15 years when they are properly maintained.

In addition to saving an estimated $180 a year on energy costs, units with programmable thermostats can also make a difference with regulating the amount of heat you have in your home. If you’re planning to take a winter vacation or tend to be away from home during the day, you can keep it set at 60 degrees and adjust the temperature once you return home.

A major part of properly maintaining your system is to change the filters regularly. When a heating and air conditioning system isn’t functioning optimally, it’s possible the filters aren’t being changed often enough. These filters should be replaced at least once every three months. Some contractors, however, may recommended replacing them once a month.

When you change your filters regularly, it also makes a difference in your home’s air quality. These filters trap allergens, dust, and dirt that can build up and then circulate throughout your home.

Other steps that you can take include having contractors evaluate your attic to make sure that it has sufficient ventilation and insulation. In addition to improving overall energy efficiency, it can also make a 10%-to-12% difference on your monthly bills. By taking care of home renovations and repairs, along with purchasing a high-efficiency heating and cooling system, you will improve your home’s air quality and environment.
