Frontenac, MO

If the AC was off and you just turned it on, it would take about three hours to chill a four-bedroom home by 10 degrees Fahrenheit. If the air conditioner was already on and you’ve adjusted it to a colder temperature, cooling your Frontenac home will likely take less than an hour. Although the cooling power of your air conditioner is dependent on its size, age and wattage, your home should feel noticeably cooler pretty quickly.

In general, most HVAC systems will last 15 to 25 years, however this estimate can be extremely varied depending on the kind of system and other contributing factors. Even with routine maintenance and repairs, even the most advanced boilers, furnaces, heat pumps and air conditioners will ultimately need repairs and eventual replacement.

There are a number of factors that might shorten the life of HVAC equipment, including:

• Inadequate maintenance.
• Defective components or poor initial quality.
• Improper installation techniques, such as oversizing or undersizing the system.
• Unreasonably high use or loads.

The quickest and easiest way is to keep up with air filter replacement. Dust and particles accumulate on air filters. The caked dirt will restrict airflow if you don't change them on a regular basis. As a result, your air conditioner will work harder (and your energy cost will rise) without really cooling your home. The frequency with which you should change your air filters is determined by the number of people who reside in your house, if you have pets, whether you have allergies and the type of air filters you have. Once a month, have a look at them. Replace them if they appear to be filthy.
