When installation is the job
Five houses that need a furnace chosen for them.
Installing is a design job before it is a labor job, and the choosing matters more than the badge on the box. These are the five situations where a furnace needs specifying rather than simply swapping.
There is no furnace there yet.
New construction, a whole-house remodel, or a converted space the heating never reached. The size comes off the house plan rather than off an old nameplate.
You are changing fuel or system type.
Gas going in where there was electric strip heat, or a heat pump covering both seasons. That is a design decision before it is an installation.
The house has grown since the last one went in.
An addition, a converted garage or a wall of new glass moves the heating load, and the old size stops matching the house it is in.
The ductwork was never right.
A furnace can only push what the duct system will carry. An install is the one chance to correct an undersized return and a starved plenum while everything is open.
You want the efficiency you are paying for.
A condensing furnace only delivers its rating if the venting, the combustion air and the condensate drain are done properly. That is an install-quality question, not an equipment one.
Gas, electric or heat pump
Choosing the right furnace for a Texas house.
Texas winters are short and sharp. The right answer depends on your fuel, your ductwork and your bills, so we walk the options with numbers rather than a script.

Install day, in the order it happens.
Sizing before buying
Square footage, insulation, glass and duct capacity, worked out before anybody talks about equipment. The furnace is sized from the house, never from the badge on the old one.
Two or three real choices
Gas, high-efficiency gas, electric or a heat pump, each with the price, the running cost and the catch spelled out. Nothing goes on the list that we would not fit in our own house.
Clear the space and set the base
Floors and walkways covered, the old unit out where there is one, then venting, gas line and electrical checked before a new cabinet goes anywhere near the space.
Connected and commissioned
Set, vented, gassed and wired, then combustion analyzed, gas pressure set and temperature rise measured under load. The thermostat is configured with you standing there.
Hauled away and registered
Old equipment gone, the area swept, the manufacturer warranty registered in your name, and a call after the first genuinely cold night.
What the install costs
Three specifications, and what separates them.
A new system installed runs $8,500 to $20,000, depending on tonnage, efficiency and ductwork, because two houses on the same street can need different furnaces. We show you the tiers and tell you exactly what moved yours.
Standard gas or electric
The simplest specification: the right size, fitted cleanly, nothing gold-plated.
High-efficiency, done properly
The usual choice. A condensing furnace only pays back when the venting and drain are right, so that work is inside the price.
Heating and cooling in one install
Best value when the cooling side is the same age, or when a heat pump can cover both seasons.
Surprises after the estimate. Written, itemized price before a wrench is turned. Free second opinion on any other company’s quote. Financing available. Manufacturer warranty registered for you.
Upfront furnace installation pricing
Three things are fixed before anything is ordered: the in-home estimate is free, the written quote is itemized line by line, and the number on it is the number you pay. Nothing gets added on install day without you approving it first.
New system installed
$8,500 to $20,000
AC, furnace, matched system or heat pump, sized for the house and quoted in writing after a visit.
Most repairs
$150 to $4,500
The other half of the repair-versus-replace comparison, from a capacitor to a compressor.
Diagnostic visit
$45
Per visit. You hear the fault and the repair price before any work starts.
What sets the number
The in-home estimate is free and covers the load calculation, two or three written options, removal and disposal of any old equipment, the permit where the city requires one, and the manufacturer warranty registered in your name. Financing is available.
Does the BTU per square foot rule size a furnace?
Only roughly. The old rule puts a North Texas house somewhere around 30 to 40 BTU of heating per square foot, which is a sanity check rather than a specification. It takes no account of insulation, ceiling height, glass or how leaky the house is, and used on its own it usually oversizes. An oversized furnace short-cycles, heats unevenly and wears its igniter out early, so the rule costs you money in the end. We run the load calculation and show you the number the furnace was actually sized from.
“Called to have full gas heating/cooling system replaced and they had it done the next day.”

Aftercare
Living with the new furnace.
The filter size, written down
We leave the correct size on the cabinet, because the wrong filter forced into the slot is how a brand new furnace earns its first limit trip. Kaufman County dust and construction along US-80 load a filter faster than the box promises.
The first fall tune-up
Burners, flame sensor, igniter and venting checked before the first cold snap. Annual service is what the manufacturer warranty terms assume, and maintenance plan members save up to $300 a year.
What the new furnace should not do
A click with no light, a burning smell once the first few runs are behind it, or short cycling all mean call us. A smell of gas means leave the house and call the gas company first.

What customers say about their installs
Install customers on how the day actually went
“Cyclone replaced my AC unit and furnace in fall of 2018 and did a great job. About a year later, my thermostat stopped working. Mario responded immediately to my call, replaced the unit the next day … He is always responsive, on time, and professional.”
Austin M. · 5-star Google review, Forney listing
“Very responsible and very knowledgable regarding our Central Air needs – and very honest! … replaced our traditional furnace and A/C with an electric heat pump and the unit is working beautifully.”
Mike M. · 5-star Google review, Forney listing
“Contacted Cyclone back in January after going back in forth with a previous company that installed our new unit incorrectly and that was not heating. Mario came right out the next day advised me of what needed to be done and completed the work the following day.”
