Why Dalton Heating & Air Is San Lorenzo’s Preferred Heat Pump Installation Company

San Lorenzo homeowners call us because they’ve been burned before. A tech who quoted one number and billed another. A crew that showed up three hours late and left coffee cups in the flower bed. A system that never quite hit setpoint on a 98°F afternoon. We run on The Garrison Code: arrive inside the stated window, put the price in writing before starting, do the job by the book, leave the site cleaner than we found it, and stand behind the work for a full year. It’s printed discipline, not a slogan.

Marco Benitez runs our San Lorenzo service area, and he holds his crews to that standard on every call. Background-checked, uniformed technicians come to your door. You’ll know their name before they ring the bell. They service nine major residential HVAC brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. So whatever is in your house now, we can likely work on it or replace it without a fight.

Response time to San Lorenzo matters when your heat pump quits on a hot afternoon or a 38°F winter morning. We prioritize no-heat and no-cooling calls, and our Bay Area dispatch office coordinates local crews so you’re not waiting on someone driving across a bridge to reach you.

Heat Pump Service in San Lorenzo

Heat Pump Service in San Lorenzo means a technician checks both sides of the system: the cooling side that handles those high-90s summer afternoons and the heating side that has to carry real load on winter mornings when it dips into the 30s. That dual role is why heat pumps here need more attention than a furnace-only or AC-only setup. A service call usually runs $150 – $650 depending on what we find. If it’s a failing capacitor, a dirty coil, a low refrigerant charge, or a reversing valve that won’t switch modes, we fix it and hand you a written guarantee on the repair. If the repair fails within a year, we come back at no charge. That’s the 365-Day Done Right Promise, and it’s included with every service call.

What We Check on Every Service Visit

Refrigerant charge on both circuits, electrical connections tightened, coil condition, reversing valve operation, capacitor health, and thermostat calibration. A San Lorenzo heat pump that’s not holding setpoint usually has one of three causes: a refrigerant leak, a control board issue, or airflow restrictions from dirty filters or undersized returns. We find it, show you what we found, and quote the fix before turning a single screw.

Repair vs. Replace on Older Systems

If your heat pump is over 12 years old, still running on R-22 refrigerant, and the repair quote pushes past $600, we’ll tell you straight: that money may be better spent toward a new system. We don’t make that call for you. We give you the math and let you decide. No pressure, no upsell script.

Heat Pump Replacement in San Lorenzo

Heat Pump Replacement in San Lorenzo usually means pulling out a tired system that’s lost capacity or efficiency and installing a properly sized, modern heat pump. A full replacement runs $3,500 – $7,500 depending on the equipment, the state of your ductwork, and whether we’re doing a straight swap or fixing airflow problems along the way. The biggest mistake we see is reusing old ducts without checking static pressure. In San Lorenzo’s housing stock, undersized returns and leaky supply runs are common. A new 3-ton heat pump hooked to a return built for a 2-ton system will never perform right and will run harder than it should.

When Replacement Beats Repair

If your compressor has failed, the system is over a decade old, and efficiency has dropped to the point where your PG&E bill climbs every summer, replacement often costs less over five years than continuing to patch an old unit. We’ll show you the numbers on paper, including what a higher SEER2 rating does to your actual bill.

What a Proper Replacement Includes

New outdoor unit, matched indoor coil or air handler, new or verified line set, thermostat check, and a startup sequence that verifies the system is pulling the right amps and hitting the right temperature split. Every replacement comes with a written price before we order equipment, a written guarantee on the installation, and a full year of coverage through the 365-Day Done Right Promise. If something isn’t right in that first year, we return and make it right, no charge.

Trusted Brands We Service in San Lorenzo

We install and service Goodman, Rheem, York, Daikin, and the rest of the major residential brands. Our Bay Area parts suppliers stock most common components locally, which means a failed control board or a leaking coil in San Lorenzo doesn’t have to wait on a shipment from Texas. We quote the job with the right equipment for your home’s size and ductwork, not whatever’s sitting in the warehouse. Some San Lorenzo homeowners come in wanting a specific brand because a neighbor has one. We’ll tell you honestly if that’s the right fit or if another brand’s sizing and efficiency profile matches your house better. The decision stays yours.

Common Heat Pump Installation Problems We See in San Lorenzo Homes

• Skipping the load calculation and upsizing “to be safe.” In San Lorenzo’s inland climate, an oversized heat pump short cycles, leaves humidity in the air on muggy days, and runs up higher bills than a correctly sized unit ever would. Bigger is not better. It’s just bigger.
• Reusing old R-22 line sets without checking for contamination. Old line sets carry acid and debris from a dying compressor. Flushing them isn’t always enough. We check and replace when needed, because a contaminated line set can kill a brand-new heat pump and void the manufacturer’s warranty.
• Ignoring the heating side because “it’s the Bay Area.” San Lorenzo winter mornings hit the 30s regularly. That’s a real heating load. If a contractor sizes a heat pump only for cooling and assumes the strip heat will cover winter, you’ll get high electric bills and cold rooms in January.
• Leaky or undersized ductwork left as-is. Most San Lorenzo homes date to the 1950s and 1960s. Duct leakage of 20 – 30% is common. A new heat pump connected to leaky ducts runs harder, costs more to operate, and can’t hit setpoint on a 98°F afternoon no matter how many tons it’s rated for.

Here’s the specific local reality we see all the time: San Lorenzo’s inland East Bay position means summer design temperatures routinely reach the high 90s while winter mornings still drop into the 30s. That’s a genuine dual load. A heat pump here has to be sized for both, not just treated like a mild-coast AC unit. When someone sizes a San Lorenzo heat pump using “Bay Area mild” assumptions, the heating side comes up short in January and you end up running expensive strip heat. We were called to a 1960s ranch in the Bockman Road area where the homeowner’s old AC had finally quit and they wanted a heat pump instead. Our tech ran a load calculation and found the existing ductwork had high static pressure and a return that was too small for a 3-ton system, so we upsized the return, sealed the leaks, and installed a properly matched heat pump with a new thermostat calibration. The result was a system that could actually hit setpoint on a 98°F afternoon without running nonstop.
