The short answer
Yes, SwiftAir Conditioning Repair serves Lexington Hills from our San Jose base, about 16 miles away. We handle AC and heating repair, furnace and heat pump installation, ductless mini-splits, maintenance, duct cleaning, and indoor air quality work.
Lexington Hills is an unincorporated community in Santa Clara County, about 16 miles south of our base in San Jose. SwiftAir Conditioning Repair travels there for heating and cooling repair, new system installation, and routine maintenance. This page explains how we approach homes in the area, what the Bay Area Air District appliance rules mean if your furnace or water heater needs replacing, and what to check before you choose a heat pump.
Heating and Cooling Needs in Lexington Hills
The Santa Clara Valley has a Mediterranean climate, with dry summers and mild, damp winters. Inland and southern parts of the valley run noticeably hotter in summer than areas near the Bay, and Lexington Hills sits well to the south. Many households here run heat on cool, damp mornings and evenings in winter, then switch to cooling during dry summer stretches. Equipment that works in both seasons gets little rest, so small problems often surface when the weather turns.
Many homes in the hills sit on sloped or wooded lots. Outdoor units can collect leaves and debris, and duct runs through attics or crawlspaces may be longer than in a typical valley home. We look at your specific layout on every visit instead of assuming a standard setup.
- Air conditioner running but blowing warm or barely cool air
- Furnace or heat pump turning on and off in short cycles
- Ice on the refrigerant lines or outdoor unit
- Some rooms much warmer or cooler than others
- A musty smell from the vents when heat first comes on in the damp season
- Energy bills climbing without a change in how you use the system

Replacing a Furnace or Water Heater: What the Air District Rules Mean
Lexington Hills is covered by Bay Area Air District rules for gas appliances. These rules do not require you to replace working equipment. They apply only when an existing furnace or water heater fails or is replaced.
Under Rule 9-4, natural gas furnaces manufactured from 2029 must meet a zero-NOx emission standard. In practice, that points homeowners toward heat pumps when a furnace is replaced after that date. If your furnace is aging, it is worth thinking about your options now rather than during an emergency.
For small water heaters, Rule 9-6 set the zero-NOx date for 2027. The Air District Board is considering amendments in November 2026 that could delay it, so check the current rule before planning a water heater replacement. We can walk you through where things stand when you call.
Heat Pumps, Ductless Systems, and Incentives
A heat pump handles both heating and cooling, which fits the mild winters and warm, dry summers of the southern valley. For homes with ducts in good shape, a ducted heat pump can often use the existing system. For homes without ducts, or for a single room that never stays comfortable, a ductless mini-split is often a practical choice.
On incentives, be aware that the federal Energy Efficient Home Improvement Credit (25C) covered qualifying heat pumps placed in service before December 31, 2025. It is not available for new installations after that date. Bay Area homeowners can still check BayREN and their local clean energy provider for current heat pump and electrification incentives. Amounts and availability change by funding cycle, so we confirm the current offer before including it in a quote.
Maintenance, Ductwork, and Indoor Air
Dry summers can leave dust in ducts and filters, and damp winters can bring moisture-related odors. A maintenance visit before each season lets us clean components, check refrigerant and electrical connections, and catch worn parts before they fail. If you notice dust, stale air, or uneven airflow, duct cleaning and indoor air quality improvements can help.
