New Heating Installation and Replacement Across the Valley

Day & Night Air Conditioning, Heating, and Plumbing installs and replaces heating systems for homes across the Valley of the Sun.

A new heating system is a long-term investment, so our licensed technicians help you choose between a gas furnace, an electric furnace, and a heat pump before anything is installed. We work on all major heating systems, size each unit to your home, and complete every connection to Arizona code.

With over 40 years of local experience and active Arizona licenses ROC335883 and ROC335884, we know what Valley homes need on the cold nights. You get an estimate before any work starts, next-day installation on most systems, and a clean, code-compliant install.

When your old system is worn out or unsafe, we honestly recommend replacing it rather than pushing another repair.

When to Replace Your Heating System

Replace your heating system when it is more than 10 to 15 years old, needs frequent repairs, or costs more to fix than a new unit. A system leaking carbon monoxide or unable to keep your home warm should be replaced right away. For newer systems with a single fault, repair is usually the better call. Most heating systems in the Valley give plenty of warning before they fail. The following signs usually mean replacement is the better option:
  • Age: A furnace lasts about 15 to 20 years, and a heat pump around 15. Past that, efficiency and reliability drop.
  • Rising energy bills: A less-efficient system works harder to heat the same home, and the cost shows up on your bill.
  • Frequent repairs: When repairs start stacking up, you’re often better off replacing the system.
  • Uneven or weak heat: Rooms that never warm up can mean the system is undersized or wearing out.
  • A safety issue: A cracked heat exchanger or a carbon monoxide risk means the unit should be replaced, not repaired.
Our certified technicians assess your system, explain what they find, and give you an honest recommendation on whether to repair or replace. When a new system is the better investment, we size it to your home and lay out the cost upfront. Call us to find out whether a repair or replacement makes sense for your home.

Choosing the Right Heating System for Your Home

For most Valley homes, a heat pump is the efficient all-in-one choice, while a gas furnace suits homes with an existing gas line that want strong, fast heat. Our certified technicians size either option to your home and help you weigh the cost, your setup, and your heating preferences. We install gas and electric furnaces and heat pumps.

Furnace Installation and Replacement

A furnace installation delivers steady, powerful heat and costs less than a heat pump. A gas furnace burns natural gas and needs a secure gas line and proper venting, while an electric furnace heats through elements and connects to your home's electrical panel. Both push warm air through your existing ducts.

A furnace is a good option for homes that already run gas appliances or recently replaced their air conditioner, since the furnace pairs with the existing AC. Our technicians size the unit to your home's square footage and layout, because an oversized furnace short-cycles and wastes energy while an undersized one never keeps up. We handle the gas or electrical connections, venting, and safety checks that keep the system running.

Heat Pump Installation and Replacement

A heat pump installation provides heating and cooling in one system, ideal for the Valley, where cooling matters far more than heating. Instead of burning fuel, a heat pump moves heat, pulling warmth from the outside air into your home in winter and reversing in summer. That makes it efficient to run and lets a single unit cover the whole Valley year.

Heat pumps suit homes with electric heat and those looking to replace an aging furnace and AC at once. On the handful of Valley nights below about 40 degrees, a heat pump can lean on backup heat, which our technicians factor into the sizing. Modern units add features like variable-speed operation for steadier temperatures and lower energy use. We size the system to your home and set it up for efficient year-round performance.

What a Heating Installation Includes

Our heating installation service includes removing the old unit, installing the new furnace or heat pump to Arizona code, connecting the gas, electric, and venting, setting the thermostat, and testing the system before we leave. We pull any required permit and give you an upfront price before the work starts. Every job ends with a full test and a walkthrough. Here is what a Day & Night heating installation includes:
  • An upfront quote you approve before any work begins, with no hidden costs
  • Removal and haul-away of your old furnace or heat pump
  • Code-compliant connections for gas, electric, and venting, done to Arizona standards
  • A required permit where the local jurisdiction calls for one, handled by our team
  • Thermostat setup and a check that the system cycles correctly
  • A full system test to confirm safe, efficient operation before we leave
  • A walkthrough of your new system, so you know how to run and maintain it
Skipping any of these steps can waste energy, cause early breakdowns, or create safety risks like a gas leak or weak airflow. Our technicians do it right the first time, so your system runs safely and efficiently for years.

Why Choose Day & Night for Heating Installation

Valley homeowners choose Day & Night for clean, code-compliant heating installs from certified technicians who size the system right. We back each heating installation with a strong warranty and quote the full cost before we start.

  • Four Decades of Heating Experience. Our certified technicians bring over 40 years of heating experience to homes across the Valley, so we have installed in nearly every type of home in the metro, from older central neighborhoods to newer master-planned builds.
  • Licensed Arizona Contractor. We hold active Arizona contractor licenses ROC335883 and ROC335884, so every install is permitted, inspected, and completed to current state code, not cut short to save time.
  • Best-in-Class Warranties. Every new installation is backed by a 10-year parts and labor warranty, so the cost of a covered part or repair down the road does not land back on you after our crew leaves.
  • Next-Day Installation. On most new systems, we can install the next day, so a failed heater in a cold snap does not leave your family waiting days for heat while quotes and parts are sorted out.
  • Correct Sizing Every Time. We size each furnace or heat pump to your home’s square footage and layout, because a unit that is too large or too small wastes energy, wears out early, and never holds a steady temperature.
  • Honest Repair-or-Replace Advice. When your current system still has life left, we say so. You get a straight recommendation based on the unit’s age and condition, never a push toward the bigger sale.
  • VIP Club Savings. Members of our VIP Club get priority scheduling and member savings on future service, which keeps your new system tuned and protected year after year.

Heating Installation Financing

A new heating system is a major purchase, so Day & Night offers financing to make it manageable. Instead of paying the full cost at once, you can spread a furnace or heat pump installation into monthly payments that fit your budget. This lets you install the right system now instead of delaying a replacement or settling for a cheaper unit.

With approved credit, our financing keeps a quality installation within reach. Ask about current terms when you schedule your estimate, and we will walk you through the options.

Current Specials

Day & Night runs seasonal specials that can lower the cost of a new heating system.

Frequently Asked Questions

The cost depends on the system type, size, efficiency, and installation complexity. A standard furnace usually costs less upfront than a heat pump, which replaces both your heater and air conditioner in one system. Our technicians give you an upfront price before any work begins, so you approve the full cost first.

Most heating installations are completed in a single day, and we offer next-day installation on most systems. A straight furnace or heat pump replacement is quickest, while adding a gas line, new venting, or ductwork takes longer. We give you a clear timeframe before we start.

It depends on your home and how you heat it. A heat pump suits most Valley homes since it heats and cools in one efficient system, while a gas furnace is a strong fit for homes with an existing gas line that want fast, powerful heat. Our technicians help you weigh both and size the right one for your home.

Removal and disposal are included in every installation. Our technicians disconnect and haul away your old furnace or heat pump, then install the new system. You do not have to deal with the old unit.

Day & Night backs every new installation with a 10-year parts-and-labor warranty. A correct, code-compliant install also keeps the manufacturer’s warranty valid, which is why professional installation matters.

Most Valley jurisdictions require a permit to install or replace a heating system, even for a like-for-like swap. Our team pulls the permit and installs the system to current Arizona code, so the job is done correctly and passes inspection.
