Frequently Asked Questions

Do I need a new HVAC system?
How do you know if it's time to replace your old cooling and heating equipment or improve the performance of your overall system? If you have any of the following problems, It may be time to call a professional contractor to help you make a change if?

1. Your equipment needs frequent repairs and your energy bills are going up. Nothing lasts forever, and if you're paying hundreds of dollars each year to maintain and repair your existing equipment, then it is time for a change. The cost savings will go beyond the repairs and will include decreased fuel/power costs.

2. Your heat pump or air conditioner is more than 10 years old, or your furnace or boiler is more than 15 years old. Older heat pumps and air conditioners are often about 60% efficient, but newer equipment can be over 90% efficient. What does this mean? If you have a monthly fuel or power bill of $100, you could see your energy cost drop to as little as $65/month. Ask your contractor to explain the energy rating for each system.

3. No one is home for long periods of the day and you don't have a programmable thermostat. There is no sense heating or cooling an empty house. Have a professional contractor install a programmable thermostat and instruct you on its use, to start saving energy and money while you're away or even sleeping.

4. Some of your rooms are too hot or too cold. Improper equipment operation, duct problems, or inadequate insulation could be the cause. A good HVAC contractor can analyze your zoning needs and help solve the problem.

5. Your equipment has humidity problems. Poor equipment operation, inadequate equipment, and leaky ductwork can cause the air to be too dry in the winter or too humid in the summer, breeding disease and causing health and comfort problems in your home.

6. Your home has excessive dust. Leaky ducts can pull dust in from attics, crawlspaces, and basements and distribute them through the house. Having your ducts sealed may be a simple solution.

7. Your cooling system is noisy. Undersized duct systems or problems with the indoor coil of your cooling equipment can often cause your system to overwork, producing noise and inefficient power usage.

8. Someone in your home has severe allergies. Allergies are a part of life, but some systems are more prone to growing molds and attracting dust. An inspection of your system will help you understand how to improve or replace your current system with one that is more healthful.
