Why is professional heating installation necessary?
You might be a DIY enthusiast, but heating installation is one area where professional expertise is non-negotiable. Modern heating systems are complex machines that involve high-voltage electricity, combustible gas lines, and intricate ventilation requirements.
A professional installation by One Way Heating and Cooling ensures:
Safety: We test for gas leaks and carbon monoxide to keep your family safe.
Warranty Protection: Most manufacturers require professional installation to keep your warranty valid.
Peak Efficiency: A system that isn't calibrated correctly will work harder, cost more to run, and die sooner.
Local Compliance: We ensure every connection meets El Paso building codes and safety standards.
How should you prepare your home for the big day?
Preparation is the best way to ensure the installation starts on time and finishes efficiently. While our technicians do the heavy lifting, a little bit of legwork from you goes a long way.
Clear the Path: Move any furniture, boxes, or storage items away from the furnace area. Our team needs at least three feet of clearance to work safely.
Secure Pets and Kids: Installation can be noisy, and doors may be left open as we move equipment. Keeping pets and children in a safe, separate area or out of the house for the day is highly recommended.
Check Your Utilities: Ensure our team has easy access to your electrical panel and gas shut-off valves.
Clear the Exterior: If we are installing a heat pump or outdoor component, make sure shrubs are trimmed and the area is free of debris.
What happens when the One Way team arrives?
Punctuality and respect for your property are our top priorities. When our technicians arrive, the first thing they will do is a brief walkthrough. They will confirm the installation plan with you and answer any last-minute questions.
To protect your home, we use drop cloths and shoe covers to ensure your floors stay clean throughout the process. We treat your house with the same care we would give our own.
What is the process for removing the old system?
Before the new unit can go in, the old one has to go out. This isn't as simple as just unplugging a toaster.
Safety Shutdown: We carefully turn off the gas and electricity to the unit.
Disconnection: Our technicians disconnect the old ductwork, gas lines, and electrical wiring.
Eco-Friendly Disposal: We don’t just leave the old unit on your curb. We handle the heavy lifting and ensure the old system is disposed of according to environmental regulations.
How is the new heating system installed?
This is where the magic happens. Once the area is prepped and the old unit is gone, we bring in your new, high-efficiency system.
Precision Placement: We position the new unit to ensure it is level and has proper clearance for future maintenance.
Connecting the "Vitals": We securely connect the system to your home’s gas lines and electrical circuit. These connections are double-checked for safety and stability.
Ductwork Integration: We attach the unit to your existing ductwork, sealing any gaps to prevent "conditioned" air from escaping into your attic or crawlspace.
Why do technicians spend time on testing and calibration?
The physical installation is only half the battle. A furnace that "turns on" isn't necessarily a furnace that's working at its best.
Once the unit is hooked up, we run it through several full cycles. During this time, we are:
Measuring Airflow: Ensuring heat is distributed evenly to every room.
Calibrating the Thermostat: Making sure the "brain" of your system is communicating perfectly with the unit.
Checking Safety Controls: Testing limit switches and sensors to ensure the system shuts down correctly if a problem ever arises.
Will there be a final walkthrough?
Absolutely. We never leave a job until the homeowner feels 100% confident. At the end of the day, our lead technician will walk you through the new setup.
We will show you:
How to operate your new thermostat.
Where your air filters are located and how to change them.
What signs to look for that indicate the system needs service.
How to access your 10-year parts and labor warranty information.
How long does a typical installation take?
Most standard heating installations in El Paso take between 4 and 8 hours. However, if your home requires significant ductwork repairs or if you are switching from one fuel source to another (like moving from electric to gas), it may take a bit longer. We will always provide an estimated timeline during your initial consultation so you can plan your day.
What are the long-term benefits of a new system?
Investing in a new heater from One Way Heating and Cooling pays off for years to come.
Lower Bills: Modern units can be up to 20% more efficient than those from a decade ago.
Cleaner Air: New systems offer better filtration, reducing dust and allergens in your home.
Increased Home Value: A new, warrantied HVAC system is a huge selling point if you ever decide to move.
Peace of Mind: With 24/7 emergency service and our expert backup, you’ll never have to worry about a freezing night in El Paso.

Frequently Asked Questions
Do I need to replace my ductwork when I get a new heater?
Not always. Our technicians will inspect your existing ducts. If they are in good condition and the right size for your new unit, we can reuse them. However, if we find major leaks or if the ducts are too small for the new system’s airflow, we may recommend repairs or upgrades to ensure you get the efficiency you’re paying for.
Is it normal to smell something when the new heater first turns on?
Yes. It is very common to notice a "burning" or "dusty" smell during the first cycle of a new furnace. This is simply the manufacturing oils or dust that settled during shipping burning off the heat exchanger. It should dissipate within an hour. If the smell persists or smells like rotten eggs (gas), call us immediately.
Should I upgrade to a smart thermostat during installation?
We highly recommend it. A smart thermostat allows you to maximize the energy-saving features of your new heater. You can set schedules and control your home's temperature from your phone, ensuring you aren't wasting money heating an empty house.
How often should I maintain my new heating system?
To keep your warranty valid and your system running efficiently, you should have it professionally serviced once a year. We recommend scheduling a "tune-up" in the fall before the first cold snap hits El Paso.
What is the average lifespan of a new furnace?
With proper maintenance, a modern gas furnace typically lasts 15 to 20 years. Heat pumps usually have a lifespan of 10 to 15 years. Regular filter changes and annual inspections are the best ways to reach the upper end of those ranges.
