Frequently Asked Questions

Q: How can I increase the efficiency and life of my home’s heating and cooling systems?

 

A: The most important thing you can do is clean and replace your filters frequently and have a professional tune it up twice annually, one for heating and one for cooling.

 

Q: Is a system with a larger capacity better?

 

A: Not necessarily, a larger system with more capacity can deliver less comfort and cost more to operate. An AC unit is at its least efficient when it’s initially cycling on. A system with an excessive capacity will run in multiple short cycles, causing it to turn on and off numerous times, which leads to less efficiency. Additionally a system only removes humidity when it is running, and having short run cycles causes the system to not remove humidity as well, and could also lead to mold building up within the home.

Q: How long should my system run?

 

A: This typically depends on the needs of the home as well as taking changing weather into account. The hotter or colder the weather is, the more the equipment may run.

Q: What air temperature should my air conditioner produce?

 

A: The air temperature that your unit creates is based on several factors. The temperature outside going into the system will affect your temperature indoors. Typically, the air generated will be around 20 degrees below what enters the unit. However this formula mainly works on units that have been running for at least 15 minutes on a warm day. On a mild or humid day the air produced may be 15 degrees cooler than what enters your unit. Another factor to take into consideration is how well your duct system is sealed, if there are any tears or breaks you could potentially be losing several degrees in your home.

Q: What temperature should I set my thermostat?

 

A: Depending on the season and time of year you should have different settings. During the summer months it is typical to set your thermostat to 76-78 degrees and 68-70 degrees in the winter. When leaving your home do not set the temperature more than 5 degrees back from its usual setting, this will place stress on your system and could lead to potential problems.

Q: How often should I replace my filters?

 

A: To achieve maximum efficiency and filtration, we suggest that you replace your disposable filters once a month. We do not recommend washable filters unless they are utilized for electronic filtration systems.

Q: How often should I have maintenance performed on my air conditioning system?

 

A: We recommend having a professional inspect and perform a preventative maintenance on your air conditioner twice a year to ensure maximum efficiency. This helps us plan ahead for any issues you may run into in the future and gives us an opportunity to remedy any situations before they become problems. We offer a Total Care program that is specifically designed to keep your system running at its highest efficiency year round.

Q: Is there anything I should look for before calling for service?

 

A: Absolutely! Initially check that the air handler or furnace is turned on, check that all breakers and disconnects are turned on, and inspect your thermostat to ensure that it is at the correct setting.

Q: Why are humidifiers used more in heating than cooling?

 

A: When cool outdoor air enters your home it tends to dry out as it warms up, this causes an increase in static electricity inside, and could lead to sinus issues. By placing a humidifier in your home, you add moisture back into the air and limit any sinus problems that may arise. During the summer, air conditioners use the system to remove humidity.
