Lennox System Maintenance and Installation in Houston & Surrounding Cities

Davis Truck Side

Greater Houston homeowners need and rely on their heating and cooling systems for year-round comfort. Lennox systems, whether air conditioning, heat pump, or furnace, provide energy-efficient, reliable comfort whether the temperatures are in the 20’s or 90’s. Home and business owners can also count on our NATE-certified technicians and management team to provide an excellent service experience for any maintenance, repair, or installation service appointment throughout the lifespan of the Lennox equipment.


Lennox Installations for Areas Including Houston, Ft. Bend, Galveston & Brazoria Counties

Installing a new Lennox furnace or heat pump begins with a load calculation that defines the capacity requirements for the home or business. A load calculation includes information about the structure orientation, number of windows, insulation, and more. The importance of this assessment is critical. A system that is too large will short-cycle, causing the system to turn on and off frequently without cooling or heating the rooms at the end of the ductwork line. A system that is too small will run continuously, trying unsuccessfully to reach the thermostat temperature.

This will create high energy bills, put undue stress on the system, shorten its lifespan, and cause uncomfortable temperatures inside for families or employees. At Davis Air Conditioning & Heating, Inc., we perform an energy assessment and complete a Manual J load calculation to ensure that your Lennox installation will be as energy-efficient as possible. Our factory-trained and NATE-certified technicians will complete the installation to Lennox specifications. You can be assured that your Lennox air conditioning system will keep you cool all summer and reduce humidity along with the temperature. Your Lennox heating system will keep everyone warm and comfortable during the cooler months.
