How do I know whether my heating and cooling equipment needs replacement or just repair?

Not an easy question to answer, but here are some factors to consider:

  • The age of the current system. Today, any system that is more than ten years old is probably behind the times in terms of efficiency
  • Does the current system provide the level of comfort that you want? There is a growing difference between “builder grade” and consumer choice in what a system can offer in terms of comfort and convenience.
  • How much will the repairs cost…and how many more repairs will you need in the future? Is keeping an older system operational worth the time, the money and the inconvenience? Sometimes you need to know when to cut bait and say goodbye to your old heater or air conditioner.
When should I replace my existing heating and/or air conditioning unit system?

All systems and units are different. Here are some rough lifespan guidelines to help you decide whether fixing or replacing is the right decision:

  • Average Lifetime of an Air Conditioner: 12-15 years
  • Average Lifetime of a Furnace: 15-20 years
  • Average Lifetime of a Boiler: 15-20 years
What regular maintenance do heating and air conditioning systems need?

The most important part of HVAC maintenance 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.

Should I close the registers and doors to areas of the home that I do not use on a regular basis?

No. Every system is designed to cool a certain number of square feet. By closing registers and doors in certain rooms, you disrupt and decrease the systems’ airflow and efficiency. Your system will have to work harder to cool less space, making it cycle more and become less efficient.

At what temperature should I set my thermostat?

Temperature settings depend on the time of year and your personal preferences. In the summer, the average temperature setting is 75°-80°. In the winter 68°-72° is the norm. Remember, when leaving your house; try to avoid drastic temperature changes. Do not set your temperature back more than 5°; this will cause your unit to work harder to achieve the desired temperature setting.

Is variable speed equipment superior and /or necessary?

Variable speed refers to a furnace’s or air handler’s indoor blower motor. Different speeds control the flow of air throughout your home. Variable speed blowers automatically change speeds to meet the different airflow needs of the heating and cooling cycles. Variable speed motors can use 1/7th the energy and are excellent for customizing comfort levels in different zones of your home. A variable speed motor can also help clean the air and control the humidity.
