Additional HVAC Services and Features

Indoor Air Quality

Health problems like allergies and asthma can be aggravated by poor indoor air quality. There are solutions to cleaning and improving the air in your home. Identify the sources of air pollutants and eliminate or reduce them. Although, it is almost impossible to remove every source that may emit pollutants, reducing them will contribute to a healthier environment. Frequent dusting and vacuuming can reduce the amount of dust particles in the air. Bacteria and volatile organic compounds are more difficult to remove. A Lennox Healthy Climate PureAir air purification system can help to remove irritants and purify your home’s air. To find out more about how a PureAir system can improve the quality of your indoor air call Carlisle Petroleum for a no cost in-home estimate and start breathing easier.

Ductless Heating and Cooling

Ductless HVAC systems can be a solution to heat and cool areas that are not easily accessible for duct installation. This application can be perfect for additions and older homes where the integrity of the structure needs to be maintained. Ductless heating and cooling systems offer higher efficiency and several indoor units can be installed with just one outdoor unit. Please call to schedule a free in-home estimate.


In the winter humidity is low and heating systems can make indoor air dry. Dry air can cause static electricity, dry itchy skin, nose bleeds and aggravates respiratory ailments like asthma, colds and sinus infections. When we humidify air it feels warmer and more comfortable and can save on heating costs. Portable units only humidify one room and are inconvenient to maintain. A Lennox Healthy Climate humidifier can release moisture and circulate it through your entire home when the heating system is in operation. To find out more about the best solution to improve your home’s indoor air quality call Carlisle Petroleum and speak to a Home Comfort Advisor.
