Furnaces

FurnaceCullen Heating & Air Conditioning is a proud retailer for Comfortmaker furnaces. Let us help you select your next home heating solution!

Two Stages, More Comfort

The sturdy steel cabinet is thermal-lined and insulated to reduce the amount of heat and operating noise that escapes. A sealed-blower compartment, soft-mount components, and variable-speed blower motor also reduce operating sounds. When matched with select Comfortmaker air conditioners and evaporator coils, the ECM variable-speed blower motor can also boost cooling efficiency for increased SEER rating.

Warranties That Work for You

Comfortmaker units are backed by exceptional warranties, including the No Hassle Replacement™ limited warranty, which gives the original purchaser a replacement unit if the stainless-steel heat exchanger should fail due to defect within the first 10 years. Upon timely registration, you also get a 10-year parts limited warranty and a lifetime limited warranty on the heat exchanger.

Seal Your Home Against Winter

The heart of every furnace is the heat exchanger. The proven RPJ® (Rigid Press Joint) stainless steel heat exchanger is designed to move more heat to the outside surface for increased heat transfer. The weld-free interlocking clamshell design reduces cracking or separating over the life of the gas furnace. Stainless steel construction adds durability and resists corrosion. The RPJ heat exchanger plays a significant role in boosting this model’s efficiency to a 96% AFUE rating. So, you can count on energy savings – especially compared to an older, less-efficient furnace.

What You Should Know About Indoor Air Quality

What you don’t see can hurt you! Visible dust makes up only 1% of all the particles in the air. Many more unseen particles float in the air currents inside your home. Particles sized less than 1 micron can gain the easiest entry to your body and place the biggest burden on its defense system.

How a Honeywell Electronic Air Cleaner Works

Two-stage electrostatic precipitation electrically charges air particles to create an effective method for capturing airborne contaminants.

Stage 1 – Charging Section

  • Most large particles are caught on the pre-filter screen.

  • Smaller particles flow through the screen to the first section of the air cleaner cell, where they pass through a series of high-voltage ionizing wires – more than 8,000 volts – and become electrically charged.

Stage 2: Collector Section

  • Charged particles advance through the cell to the collecting section.

  • The charged particles are attracted like magnets to a series of oppositely charged collector plates.

  • Electronically filtered air is circulated back into your home
