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

Cullen Heating & Air Conditioning is an expert at converting your home heating from electric baseboard to natural gas heating. If there is gas on your street, we will apply for a gas meter for you. Once the meter has been ordered and installed, you are ready to convert your home to natural gas.

Our technicians are professionals in custom ductwork for your home. The cost associated with this conversion used to be high. Call for pricing.

The money saved on converting from electric to gas will be tremendous. If you require financing to help pay for the conversion, the savings from what you were paying for hydro to what you will now pay for the loan for the conversion will put you further ahead at the end of the day.

Financing is available upon request! 

Let us help you decide. A free in-home estimate will determine if a conversion is right for you.
