Furnace Installation & Replacement in Menifee, Murrieta & Temecula
When it's time for a new furnace, the install matters as much as the equipment. Left Coast Air replaces and installs gas and electric furnaces across Riverside County — sized and set up correctly so you get reliable, efficient heat.
What a Furnace Installation Involves
Replacing a furnace is a chance to fix problems the old unit may have hidden. We confirm proper sizing for your home, connect the furnace correctly to your gas or electric supply, verify venting and combustion-air requirements, integrate it with your existing air handler and ductwork, and test the full heating cycle and safeties before we sign off. A clean, code-correct install — like the one pictured — is what makes a furnace safe and efficient for years.
Signs It's Time for a New Furnace
- The furnace is 15–20+ years old and needing more frequent repairs.
- A major component has failed — heat exchanger, control board, or blower.
- Heating bills keep rising as efficiency drops.
- Rooms heat unevenly, or the unit is noticeably noisier than it used to be.
- You're already replacing the AC and want a matched, efficient system.

Furnace Installation FAQs
When should I replace my furnace instead of repairing it?
Consider replacement when the furnace is roughly 15–20+ years old, needs a major or repeat repair, has a cracked heat exchanger, or has become noticeably less efficient. If a big repair costs a large share of a new unit, replacement is usually the better long-term value. See furnace repair if you're not sure yet.
Should I choose a gas or electric furnace?
It depends on what your home is already set up for and your local utility costs. Many Riverside County homes have existing gas service that makes a gas furnace straightforward, but electric heat and heat-pump options can make sense too. We'll lay out the trade-offs for your home.
Do you match the furnace to my existing AC?
Yes. When your furnace shares an air handler and ductwork with your cooling system, proper matching and airflow matter for both comfort and efficiency. We make sure the new furnace works correctly with the rest of your system.
Which furnace brands do you install?
We install all major brands, including York, Carrier, Lennox, Daikin and Maytag, and recommend the model that fits your home and budget rather than a single manufacturer.
