A heat pump is a single system that provides both heating and cooling. In summer, it works like an air conditioner — moving heat from inside to outside. In winter, it reverses — pulling heat from the outside air and moving it inside. Even in cold weather, there's enough heat in the outside air for a modern heat pump to extract it.
Who this is for: Homeowners in Santa Clara, San Jose, Sunnyvale, Mountain View, Palo Alto, Los Gatos, Santa Cruz, Cupertino, Campbell, Saratoga, Los Altos, and Milpitas. Residential and light commercial.
We size your heat pump to your home — not a square footage average. Proper sizing is more important for heat pumps than any other system.

Customers remember the details: showing up, explaining the options, protecting the home, and standing behind the system later.
“We converted our home from a gas furnace to a full electric heat pump system and upgraded to a two-zone setup, giving each floor its own temperature control. EVS guided us through every step, explained our options clearly, and made a complicated project feel straightforward. The installation was clean and completed with a high level of craftsmanship — and their pricing was the most competitive of all the quotes we received.”

“Really impressed with EVS Mechanical — they earned every one of these five stars. The heat pump they installed has been incredibly efficient, and our energy bills have actually dropped. They showed up exactly when they said they would and were careful with our home during the installation. Would absolutely recommend EVS to anyone in the Bay Area.”

“EVS Mechanical made what could have been a stressful process incredibly smooth. They diagnosed and repaired our HVAC system quickly and got everything running again. They didn't just do the work — they made sure we understood what was happening and why. Honest pricing, no upselling on things we didn't need. If you need HVAC work done right, call EVS Mechanical.”

“I called EVS for a regular furnace service and they were here very quickly. They performed the service in one day and also discovered the very old condensate pump was not working properly causing water to pool around the furnace. They replaced the pump the next day. Would definitely use their services again.”

“Euler and his team were able to replace our 23 year old attic Carrier furnace after our existing unit's heating chamber failed. I called him at 10am, and he was at my house by 11am, diagnosed the issue and found a new replacement unit and had it installed by 4pm. Very friendly and great price too.”

Ducted heat pump installations typically take one day if replacing an existing system. Ductless installations: 1 day for single-zone, 1-2 days for multi-zone. Complex installations (new ductwork, electrical panel upgrade) may take longer.
Yes. Modern heat pumps maintain full heating output well below Bay Area winter temperatures. Santa Clara, San Jose, and most Bay Area cities rarely drop below freezing — well within the operating range of any modern heat pump.
A heat pump requires electricity to run. During PG&E power shutoffs, a backup generator or battery system can keep it operating. Many Bay Area homeowners pair heat pumps with solar + battery for whole-home resilience.
For heating, yes — a heat pump delivers 3-4 units of heat for every 1 unit of electricity (300-400% efficient). A gas furnace converts gas to heat at 80-96% efficiency. The actual cost comparison depends on your local gas and electricity rates. EVS can run the numbers for your specific situation.
If you're keeping your gas furnace for backup heat, you can add a heat pump as the primary system and keep the furnace for the coldest days (dual fuel setup). If you want to go all-electric, the heat pump replaces the furnace entirely.
Yes. Ductless heat pumps are a type of mini split. They provide both heating and cooling from the same unit. See our mini split page for details on ductless installations.
Bay Area homeowners may qualify for BayREN rebates, PG&E energy efficiency programs, and federal tax credits (up to 30% for qualifying equipment). EVS can identify applicable incentives during the quote process.
EVS Mechanical installs Carrier, Mitsubishi, Daikin, Bosch, and Lennox heat pumps. We'll match the brand to your home, budget, and efficiency goals.
Yes. That's one of the primary reasons homeowners choose a heat pump — one system does both jobs. Installation is similar to central AC, and if you have existing ductwork, it connects the same way.
Heat pumps excel in Bay Area's mild climate (rarely below 40°F). They're 3-4x more efficient than gas furnaces, provide both heating and cooling, and work with solar panels. Traditional furnaces make sense if: you have very low gas rates, need backup heat for mountain areas (Los Gatos hills, Santa Cruz mountains), or aren't ready to upgrade your electrical panel. For most Bay Area homes, heat pumps are the better long-term investment.
1. Load calculation (Manual J) to size the system correctly. 2. Electrical assessment (panel capacity, 220V circuit). 3. Ductwork inspection (seal leaks, confirm sizing). 4. Equipment selection (brand, efficiency, features). 5. Permit pulling with your city. 6. Professional installation (refrigerant charging, airflow testing). 7. Post-install walkthrough and maintenance schedule. EVS handles all 7 steps — no shortcuts.
Watch for: weak heating or cooling, ice buildup on outdoor unit, unusual noises (grinding, squealing), higher electric bills, system running constantly, or frequent on/off cycling. Any of these means call EVS for diagnostics. Early repairs prevent expensive component failures.
San Jose summers hit 95-105°F and winters rarely drop below 40°F — ideal heat pump climate. Benefits: one system for heating + cooling, 50-70% lower energy costs vs. gas furnace + AC, cleaner air (no combustion), eligible for Bay Area rebates, works with solar panels, and quieter than older HVAC systems. Plus, you eliminate gas service fees.
Ducted heat pumps connect to your home's existing ductwork, just like central AC. They look and operate like a traditional furnace + AC system but use heat pump technology for both heating and cooling. If you have ducts, a ducted heat pump is a direct replacement for your current HVAC system — no visible indoor units, same vents you use now.
Heat pumps should be professionally serviced twice per year — spring (before cooling season) and fall (before heating season). Each service includes: filter replacement, coil cleaning, refrigerant level check, electrical connection inspection, condensate drain clearing, and airflow testing. Regular maintenance prevents 80% of breakdowns and keeps efficiency high.

Heat pumps are most efficient in climates where winter temperatures stay above freezing — which describes most of the Bay Area. In Santa Clara, San Jose, and the valley floor, a heat pump handles 100% of heating needs efficiently.
Modern Mitsubishi Hyper-Heat and Carrier systems maintain full heating output down to -13°F to -5°F. Even in the coldest Bay Area mornings (upper 20s in the Santa Cruz Mountains or Los Gatos hills), these systems don't need backup heat.
Bay Area homeowners may qualify for: - **BayREN** (Bay Area Regional Energy Network) — heat pump rebates - **PG&E** — energy efficiency rebates for qualifying equipment - **Federal tax credits** — up to 30% for qualifying heat pumps (Inflation Reduction Act) EVS can help identify which rebates apply to your specific installation.
Many Bay Area homes have existing ductwork designed for gas furnaces. Ducted heat pumps use the same ducts — the installation is similar to central AC but includes a reversing valve for heating. No new ductwork needed.
Outdoor units are anchored per code. Indoor units are mounted securely. All installations include seismic gas shutoff valves where required.
