Questions, answered.

No. Some houses keep the furnace for the coldest nights and add a heat pump for the rest. We lay out both options in the plan and say what each one needs from the panel. The choice is yours.

It depends on the house. We add up what the panel carries now and what you want to add, using a load calculation, before we choose any equipment. If the panel is full, the plan says whether a new panel or a subpanel is the smaller change.

We look at the panel and meter, the ducts or the places a duct would go, and each room's heating and cooling need. You get a written plan afterward. You can stop there.

Utility and state programs change often, and some depend on household income. We tell you which ones look open for your address when we write the plan. The program, not us, decides who qualifies, and we don't promise any amount.

A ducted system with a panel change is usually several working days, spread over the HVAC and electrical crews, plus the days the city needs for inspection. The plan gives the sequence for your house.

Yes. We pull the mechanical and electrical permits, schedule the inspections and tell you which days someone needs to be home.

We remove them, recover any refrigerant and cap the gas line to the old equipment. Closing the gas service at the meter is done by your gas utility, and we help you ask for it.

Assessments run all year. Many people plan in fall and winter so the system is in before the first hot week. If your furnace fails in January, call during business hours and we'll book the earliest slot.

Leave the house with everyone in it and call 911 before you call us. Don't go back in to find the cause. If you smell gas, do the same and call your gas utility from outside.

They are California contractor license classes. C-20 covers warm-air heating, ventilating and air-conditioning work. C-10 covers electrical work. Holding both lets one firm do the equipment and the wiring. You can look up our license on the state board's site.

Yes, as part of a plan or on their own when we have room in the schedule. We're an install and planning shop first, so repair calls in the middle of a heat wave may wait.

We choose equipment from the load calculation and your ducts, and we name the exact model in your plan. We'll tell you why we chose it and what the next size down would change.
