Project fit
Albany work is mostly small houses with no ducts, original floor furnaces and tight crawlspaces. These are the scopes that come up most, each one planned from a room-by-room load.
Conversion
Pull the original gas floor furnace or wall heater, close the floor, and replace it with a heat pump that heats every room and also cools.
Replacement & conversionCentral
A compact air handler and short, sealed duct runs under the floor, sized with Manual D so a small bungalow gets even, quiet airflow.
Ducted heat pumpsZoned
For houses with no crawlspace room, a few small heads or a concealed ceiling cassette handle living areas and bedrooms separately.
Ductless & multi-zoneEngineering
Load calcs, equipment selection and duct design for the system we install, ready for the city and your architect.
Manual J load calculationsNew space
Heating and cooling for converted attics, garage studios and backyard units, sized to that space instead of tacked onto the main system.
ADU heating & coolingIAQ
Once the floor furnace and leaky ducts are gone, an ERV or better filtration keeps the air fresh, especially during smoke season.
Ventilation & IAQRelevant East Bay work
High-end residential remodel
This job is in Berkeley, next door. The same crawlspace routing, panel planning and load-first sizing apply to most Albany bungalows.
The six-zone Fujitsu ductless system was installed, permitted, inspected, and completed as part of the home’s remodel-for-sale scope — delivering zoned heating and cooling without a conventional ducted retrofit.

A large share of Albany’s housing predates modern residential HVAC. Existing framing, compact mechanical spaces, older ductwork, previous remodels, and limited exterior area can all affect the right heat-pump approach.
3rdGen evaluates heating and cooling loads, distribution, equipment locations, duct or refrigerant routes, zoning, ventilation, access, and serviceability before locking in the system design.
Roughly 39% of Albany’s homes were built in 1939 or earlier, so tight crawlspaces, small closets and older electrical panels come up on most projects.
Original framing, prior alterations, existing ducts, and limited mechanical space can all shape how a modern heat-pump system is integrated.
On compact residential properties, outdoor-unit location needs to account for property lines, service access, clearances, routing, and the home itself.
Some homes are good candidates for central ducted heat pumps. Others may benefit from concealed, ductless, or multi-zone approaches where conventional ductwork is difficult to integrate.
When walls and ceilings are already being opened, early HVAC planning can create routing and equipment options that disappear later in construction.
Albany requires HVAC permit submittals to show the outdoor condenser location and its distance from property lines, making equipment siting worth considering early in the project.
HVAC design in Albany
Most Albany homes are compact, single-story bungalows on narrow lots in the flats below Albany Hill. A 1,200 sq ft 1920s house with a tight floor furnace or a tired gravity system rarely needs the tonnage a quick rule of thumb suggests, so we start with a room-by-room load and let the numbers pick the equipment.
Bay fog keeps Albany mild: winter design is about 40°F and summer design about 80°F. That narrow swing is why right-sized, variable-speed heat pumps run quietly here and why oversized equipment short-cycles.
ACCA Manual J design data · Berkeley (micro-climate)
Roughly four in ten Albany homes were built before 1940. Expect raised wood floors over short crawlspaces, plaster walls, original single-wall floor furnaces or wall heaters, and attics that are either tiny or have been converted into bedrooms.
Many houses have never had central ducts, which makes the first design question simple and important: is there a clean path for supply and return ducts in the crawlspace, or does a ductless or ducted-mini-split layout fit the house better?
Electrical service is the other usual constraint. Older Albany panels are often small, so we check what a heat pump, a heat pump water heater and any future EV charger will need before anything is ordered.
We model each room with its real windows, wall and ceiling insulation and orientation. In Albany the front rooms facing the street often carry most of the load because of large original windows, while back bedrooms need very little. That shapes where supply air goes.
Small Albany homes often land between 1.5 and 2.5 tons of cooling load. We pick variable-speed equipment whose low stage can idle down to those part-load hours, rather than a box sized for the hottest day of the decade.
Where we run new ducts under the floor, we size trunks and branches for real airflow and keep runs short. Low crawlspaces push us toward compact air handlers and well-sealed rigid trunks instead of long flex runs.
Once old floor furnaces and leaky ducts are gone, Albany houses get noticeably tighter. For remodels that add insulation or new windows, we look at whether an ERV or a simple balanced ventilation setup is worth adding.
Replace an original gas floor furnace or wall heater with a quiet ducted or ductless heat pump that also cools.
Replacement & conversion →A compact air handler and sealed duct layout sized to the house, for homes with enough crawlspace height.
Heat pump installation →A room-by-room load report behind the system we install, used for equipment choice and the permit.
Manual J load calculations →Single-zone or small multi-zone heat pumps for Albany ADUs, sized to Title 24 and the unit’s own load.
ADU heating & cooling →Mechanical design for kitchen, attic and addition projects while walls and ceilings are open.
HVAC for remodels →Factory-trained installation with extended Mitsubishi parts and compressor coverage on qualifying systems.
Diamond Contractor →Heat pump installs in Albany go through the City of Albany Building Division. Plans need the outdoor unit location and its distance to property lines, which matters on 25- to 35-foot-wide lots. We prepare the load calculation and equipment documentation the permit needs.
Albany is served by PG&E for delivery, with Ava Community Energy as the default generation provider. Rebate programs such as BayREN Home+ and statewide heat pump incentives change often, so we confirm what is open when we scope the job.

In a small Albany house, a half-ton of oversizing is the difference between a quiet system and one that cycles all day. So the design work happens before the equipment is chosen.
We measure rooms and windows and check the crawlspace height, attic, panel and where the outdoor unit can sit on a narrow lot.
A room-by-room heating and cooling load at Albany design conditions, roughly 40°F winter and 80°F summer.
Equipment picked to match the load at part load, then ducts or line-set routes laid out room by room.
Plans showing the condenser location and setbacks, plus load and equipment documents, filed with the Albany Building Division.
Old heater out, gas capped, floors patched, ducts or line sets in, and electrical done under the same permit.
Airflow and refrigerant charge checked against the design, inspection passed, and controls set up with you.
One scope, start to finish
Taking out a floor furnace or wall heater means patching the floor, capping gas, adding a condensate path, and often upgrading the panel. We plan those pieces together so the house is finished when we leave.
Every system is started up, airflow-checked and walked through with you before handoff.
Tell us about the projectFloor furnace or wall heater removed, gas capped, and the opening closed.
Crawlspace ducts or concealed line sets routed to the design.
Electrical capacity checked and circuits added with the permit.
Airflow, refrigerant charge and controls verified before you use it.
Cost
In Albany the biggest swing is usually whether the house can take ducts at all. Crawlspace height, a panel upgrade, floor-furnace removal and the number of zones change the number more than the brand of equipment does.
Prices as of November 2026. Complex whole-home and design-build projects can exceed these ranges. Rebates and incentives may reduce your net project cost.
Project inquiry
Send the square footage, what heats the house now, and a photo of the panel and crawlspace if you can. We will tell you if ducted, ductless or a mix makes sense before anyone visits.

FAQ
Questions Albany homeowners ask us about floor furnaces, crawlspaces, panels and heat pump sizing.
Yes, and it is one of the most common jobs we do in the area. The floor furnace comes out, the gas is capped, the floor opening is framed and closed, and a ducted or ductless heat pump heats the whole house instead of the hallway.
Often, but not always. Many Albany crawlspaces are low. We measure it on the walk-through. If ducts will not fit cleanly, a ductless or ducted mini-split layout usually works better than squeezing ducts in.
It depends on the house, which is why we run a Manual J load calculation. Small, mild-climate homes often need less capacity than a rule of thumb suggests, and an oversized unit costs more and runs worse.
Sometimes. Older Albany panels can be small. We add up the heat pump, any heat pump water heater, cooking and EV charging plans, and tell you whether the panel works, needs a load-management device or needs an upgrade.
Side yards and rear corners are typical. Albany wants the unit location and distance to property lines on the permit plans, so we pick a spot that meets setbacks, stays serviceable and keeps noise away from bedrooms, yours and the neighbors’.
Yes. Heat pump and HVAC replacements go through the City of Albany Building Division. We prepare the drawings, load calculation and equipment specs and schedule the inspection.
Usually some. Albany customers get power through PG&E with Ava Community Energy generation, and programs like BayREN and TECH Clean California have offered heat pump incentives. They change often, so we check what is open when we quote.
