Heating Installation & Replacement in Gilbert, AZ
Furnaces, heat pumps and dual-fuel systems, sized for your home. Free in-home estimates.
Replace it before it quits
The best time to replace a furnace or heat pump is before the cold night it stops working. If yours keeps needing the same repair, or parts are getting hard to find, a free estimate tells you where you stand. You get a written price and your options, and no pressure to decide that day.

Gas furnace, heat pump or both
Many Gilbert homes pair a gas furnace with central AC. Others have a heat pump that heats and cools. A dual-fuel system uses a heat pump most of the time and a gas furnace on the coldest nights. Which one fits depends on the fuel you have at the house, the condition of your ducts and what you want your utility bills to look like. We'll go over the efficiency ratings (AFUE for furnaces, HSPF for heat pumps) and what the higher-efficiency models cost compared with what they save.
Sized and installed to code
We run a load calculation instead of matching the old unit's size. Matching it can repeat a mistake made when the house was built. The installation covers venting, gas line sizing, electrical and condensate drainage, with the manufacturer's clearances and combustion air requirements met. We pull the Town of Gilbert permit and schedule the inspection, which checks the gas, electrical and venting work. That inspection is there to protect your family from carbon monoxide and electrical hazards.
If your AC is getting old too, ask us to price both together at the same visit. We install and service every make, and we're an authorized dealer for Carrier, Goodman, A/C Pro and Ruud. Financing includes 0% promotional plans for qualifying applicants, with approved credit.

Frequently asked questions
Should I repair or replace my furnace?
Compare the repair cost, the equipment's condition and whether parts are available against a replacement price. Age alone doesn't decide it. Replacement estimates are free, so you can see both numbers.
What size heating system do I need?
A load calculation decides it, based on your insulation, windows, square footage and local conditions.
Will my ducts need work?
Maybe. They need to suit the new equipment, and crushed or leaking ducts hold back even a well-chosen system. We check them at the estimate.
Is the estimate free?
Yes. You get a written price before any work starts.

Iron Horse is locally owned and services every make and model of AC, heat pump, furnace, water heater and plumbing fixture. If you got a quote for a specific brand, we can work on it.
