One room that never cools down needs a different conversation from a whole house with failing heating and AC. Tell us which rooms are uncomfortable, what equipment you have and what you want to change. We check the house before choosing the replacement.
Call (925) 999-4095 for a free installation assessment, or request a visit. We provide a written report of findings the same day. The project estimate follows the measured equipment and installation requirements.
Compare the layouts before the brands
Ducted heat pump
A ducted heat pump heats and cools through an indoor air handler and a duct system. It’s a choice to consider when you want to replace both heating and cooling. We check whether the existing ducts can carry the required airflow, along with the electrical supply and space for the indoor equipment. See heat pump installation.
Dual fuel: a heat pump with a furnace
This configuration pairs a heat pump with a compatible furnace. Controls determine which source provides heat. Keeping a furnace may be worth discussing when it is in good condition, but compatibility and the installation rules need checking first. We assess that option for your home; a generic equipment list cannot settle it.
Ductless, one room or several zones
A single-zone system serves one area with its own indoor unit. Multi-zone equipment connects several indoor units to an outdoor unit, with compatible combinations selected for the rooms. Placement matters: we need space for the indoor units, refrigerant lines and condensate drains. Start with ductless installation and the mini-split sizing calculator.
Gas furnace with central AC
A furnace supplies heat; the AC supplies cooling through the duct system. This can let you replace one failed section while keeping compatible equipment that still works. Compare furnace replacement and AC replacement. We confirm applicable equipment rules before proposing a new gas furnace.
The Department of Energy’s homeowner HVAC guide explains these basic layouts. Our visit applies the choice to your house, including its room loads and existing equipment.
What we measure and inspect
We calculate the heating and cooling load, look at the supply and return ducts, and check space and service access. The electrical supply, refrigerant piping and condensate route affect what can be reused. For gas equipment, venting and the gas connection also need review.
Bring up the room that overheats or the bedroom that never gets enough air. Those details help us investigate distribution problems before they carry over to new equipment. The home load calculator gives a preliminary estimate; it doesn’t replace an on-site load calculation.
Installation prices and what they mean
These are our reference prices with their equipment categories. The written quote follows the site assessment; it identifies the selected system and any ductwork, electrical, access or permit work.
- Furnace replacement: $6,500.
- Mid-tier system: $12,000.
- Top-tier system: $15,000+.
- Full package: $25,000, including a Daikin/Mitsubishi-class system, line set and installation work.
These figures aren’t model-specific offers or a statement of stock availability. The estimate shows what your project includes. Incentives are checked separately for the address, equipment and current program funding; the rebate finder is a starting point.
Brand choice and warranty
We are factory-trained on Daikin and Mitsubishi. You can also review Carrier and Goodman. We compare suitable equipment after establishing what the house needs.
Standard installation coverage is 10 years on manufacturer parts and 2 years on our labor. Labor coverage extends to 10 years with an active maintenance plan, at $290 per visit and two visits per year. Mitsubishi Electric M-Series and P-Series systems have separate registration and warranty terms, including the 90-day registration deadline and original-owner single-family-home conditions, explained below. The written proposal records the terms for the equipment selected.
Work you can look at
Our Goodman heat pump installation in San Ramon shows a system selected around the home’s calculated load. At The Athenian School in Danville, ductless systems gave individual classrooms their own temperature control. These are past projects with different needs. For new ductless installations today, we install Mitsubishi Electric; we continue to repair and service other mini-split brands.
After you approve the estimate
We confirm the equipment, arrange permits and agree on the installation schedule with you. After the work, we check system operation and explain the controls. Andrew, co-owner of the company, personally checks every installation. Keep the commissioning and maintenance records with your warranty paperwork.

What makes us different
Manual J load calculation. Every installation starts with a proper load calculation. Oversized systems short-cycle. Undersized systems cannot keep up. We size to your home's actual heat loss.
Equipment matched to the home. For new ductless installations, we use Mitsubishi Electric. For central AC, furnaces and ducted heat pumps, we also install brands such as Daikin and Goodman. We size the equipment to the home's load.
Owner reviews every quote. Every estimate gets my personal review before it reaches you. For installations and complex service, I meet you on-site. For routine calls, our trained technicians arrive with my license number on the invoice.
What to expect
Every job, repair or install, follows the same rhythm. No upsells dressed as "package tiers." No "today only" pricing. If the answer is "wait six months and re-evaluate," that is what we will say.
- Assess the installation
An on-site installation assessment is free. We review the existing equipment, space, ductwork, and electrical capacity for the proposed system.
- Review the written quote
The itemized quote identifies the equipment and installation scope, based on the home measurements and load calculation. Confirm any incentive eligibility before approving the project.
- Plan and install
After approval, we confirm equipment availability, schedule the work, and arrange required permits. Changes to the agreed scope need your approval.
- Commission the system
We check operation, explain the controls and record the installed equipment. The written warranty distinguishes manufacturer coverage from our labor coverage, including the Mitsubishi registration terms described above.
