Furnace installation in Simi Valley and Ventura County
Replace an aging or failing furnace with one that is sized right, vented right and wired by licensed electricians.

Done by the people who do both the electrical and the HVAC.
A furnace that is too big short-cycles and wears out early. One that is too small never keeps up. We size the replacement to your home, not just to the old unit, then handle the venting, gas connection, electrical and thermostat.
If your furnace is more than 15 years old, needs frequent repairs or is driving up your gas bill, it is worth getting a quote. We will tell you what repair and replacement each look like so you can decide.
What is included
- Home assessment and sizing. We size the furnace to the home, not just to the unit you have.
- Equipment options. Choices at different efficiency levels and budgets, explained plainly.
- Removal of the old furnace. We take out the old equipment as part of the job.
- Gas, venting and electrical. Connections done by licensed professionals and tested.
- Thermostat setup. The thermostat is connected and set up before we leave.
- Permit, testing and walkthrough. Permit where required, a full test and a walkthrough.
Signs it is time to replace
- A furnace older than 15 years
- Repairs that keep adding up
- Uneven heating or climbing gas bills
- Short cycling, loud noises or a pilot or ignition that keeps failing
Safety: If you smell gas, leave the house and call your gas utility or 911 before anything else.
