What do you need installed?

Coverage

Clear expectations and honest pricing

This is a preliminary estimate based on common system configurations. Final design, equipment, and price are confirmed after a free in-home visit with a Manual J load calculation.

How can we reach you?

* Required

We use this to send your estimate and have a comfort advisor follow up. We don't sell or share your information.

Please fill in the highlighted fields so we can send your estimate.

Right-sized for your home

System sizing depends on square footage, age, layout, and El Cajon's climate. We pull county property records to save you typing.

Tell us about your ducts

Does your home have existing ductwork?

Replacing attic ductwork is the most common add-on on our installs.
Ducted systems

We'll show central furnace, A/C, and heat pump options that use your existing ductwork. Our comfort advisor checks duct condition and airflow during the site visit.

What is your current system?

This lets us estimate your energy savings.

A system is one furnace or air handler paired with one outdoor unit. Most homes have one; some larger or two-story homes have two.
Some homes have refrigerant and drain lines roughed in from construction.
Attic installs take longer and cost a bit more.

Optional: thermostat settings

Helps us estimate savings more accurately.

Your estimated options

These are estimates, not final prices. Your exact price is confirmed at a free in-home visit.

These ranges are estimates based on common system configurations and what you told us about your home. A site visit for measurements, sizing confirmation, and installation scope per local code is required before any price is final, and the estimate may change based on what we find.
