Gas Furnace Installation for Chandler Homes: What to Know
Typically, gas furnace installation for Chandler homes takes 4-8 hours, although more complex jobs may take longer.
A professional installation will include proper sizing, removal of the old unit, safe gas and electrical hookups, startup testing, and warranty registration.
Working with a licensed and experienced contractor ensures safety, efficiency, and long-term reliability.
According to the Arizona Emergency Information Network, winter weather in Arizona can be harsh and unforgiving.
In fact, there can even be heavy snowfall, which many people don’t expect from the state.
They suggest that homeowners maintain heating equipment by having it cleaned and inspected every year.
But what happens when your current furnace needs to be replaced?
This is where Mark Daniels Air Conditioning & Heating comes in.
Here’s a thorough home furnace installation guide so you know what to expect from our Chandler HVAC contractors.
How Many Hours Does It Take to Install a Furnace?
A typical residential gas-furnace replacement is usually completed within a single workday.
It can take between 4-8 hours if it’s a straightforward “like-for-like” swap, where:
- It’s the same size
- It’s the same location
- There are no major gas, electrical, or duct changes
If the job requires any of the following, then the project can go to a full day or sometimes, multiple days:
- New ductwork
- Gas-line modifications
- Electrical upgrades
- Custom venting
- Structural work
To find how exactly how long it’d take, you should request a free estimate.
We can perform on-site load calculations and pre-installation measurements to narrow down the timeframe.
What Is Included in the Furnace Installation?
Usually, you can expect the following from a furnace installation:
- On-site consultation and sizing (load calculation)
- Written, upfront estimate and options
- Removal and disposal of the old unit
- Mechanical hookups and safety systems
- System startup, balancing, and safety testing
- Manufacturer registration and paperwork
We have financing options and multi-year maintenance programs, so consider those if they’re of interest.
Permits, Inspections, and Code Compliance for Chandler Homes
The Chandler homeowner permit manual is clear about when permits are required.
In particular, like-for-like furnace replacements are exempt from a building permit.
However, anything that changes the following often requires a permit, plus an inspection:
- Gas piping
- Venting
- Electrical service
- Structural openings
A reputable, experienced, and licensed contractor will know which jobs are exempt and which need permits.
They should be the ones to pull the permit and schedule an inspection too, if needed.
But to be sure, you should check with the city before starting work.
Day-of Installation: What Happens
Our technicians will always call 30 minutes before we arrive at your house.
Plus, we have background-checked, EPA-certified technicians who know what they’re doing.
When they get to your house, the techs will first prep the work area by laying down protective coverings.
You may be required to clear the space and provide safe access to the attic or crawlspace if needed.
Then, the techs will shut off the gas and electricity, disconnect your old furnace, and carefully remove it.
Next, they’ll set the new furnace in place, and address:
- Gas line adjustments (if needed)
- Flue/vent connections
- Electrical hookups
- Duct transitions
Should they find any unexpected issues during hookup, they’ll be flagged and quoted.
This may be anything from corroded venting or undersized gas piping, to failed duct connections.
After installation, the technicians will start up the furnace and conduct tests to ensure everything’s working.
They’ll document the readings and teach you how to use the new furnace if needed.
Lastly, they’ll give you the invoices and warranty registration (when applicable).
Post-Installation Care and Maintenance
The steps to the best protection for your furnace after installation are to:
- Change the filters regularly
- Follow the manufacturer/installer maintenance schedule
- Book annual tune-ups
To extend your furnace’s lifespan and keep efficiency high, always schedule annual inspections and cleanings.
Frequently Asked Questions (FAQs)
How to prepare for furnace installation?
If you want the day to go smoothly for your Chandler home heating installation, then first clear a 3-6 foot working area around the furnace.
You should also move breakables and small furniture, and if you have pets and children, they should be secured in another room.
Other things you should do include:
- Note where gas/electrical shutoffs are
- Have your payment or financing documents ready
- Make room for the installers’ ladder and tools
Can I install a gas furnace myself?
No, you should not install a gas furnace by yourself.
Gas-fired appliances involve:
- Combustion
- Precise gas-line work
- Venting and electrical connections
DIYing this job may result in errors, and they can be quite serious.
Possible outcomes include:
- Gas leaks
- Carbon-monoxide poisoning
- Fires
- Code violations
You should always use a licensed, insured, and EPA-certified professional.
Will a new furnace lower my energy bills?
In most cases yes, especially if you replace old, inefficient units with energy-efficient furnaces, such as ones with ENERGY STAR or high-AFUE ratings.
The system has to be properly sized and installed too.
Your exact energy savings will depend on the unit efficiency, as well as the fuel costs and home envelop tightness.
If you want to know more, then ask your installer, as they should be able to provide an estimated annual energy savings for the model you choose.
How long will my furnace last?
If you properly maintain a gas furnace, then it should last 15-20 years, or even longer if you have a high-quality install and diligent upkeep.
Your use pattern will also determine how fast your furnace breaks down.
Generally speaking, annual maintenance will maximize its service life.
