The short answer
Yes, MasterFix HVAC Repair Service serves Lexington Hills from our San Jose base, about 11 miles away, for heating and cooling repair, installation, maintenance, and air quality work. We also offer 24/7 emergency service and can help you plan around Bay Area Air District furnace rules before you replace equipment.
Lexington Hills is an unincorporated community in Santa Clara County, about 11 miles southwest of our base in San Jose. MasterFix HVAC Repair Service works on heating and cooling systems for homes here, including repairs, replacements, heat pump and ductless mini-split installations, routine maintenance, duct cleaning, and indoor air quality upgrades. Homes in the hills often deal with different conditions than houses down on the valley floor, so we look at how your house is built and how you actually use it before recommending anything. We also offer 24/7 emergency service when a furnace stops working on a cold, wet night.
Heating and Cooling Needs in the 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. Up in the hills, conditions can vary from one property to the next depending on shade, exposure, and how the house sits on its lot. That makes a one-size-fits-all approach a poor fit here.
In winter, heating is usually the bigger concern. Damp weather can be hard on equipment and ductwork in crawlspaces and attics, and a furnace that has been sitting idle all summer may show problems the first time it runs in the fall. In summer, some homes have older central air, some have none at all, and some have rooms that never quite cool down. A ductless mini-split or heat pump can be a practical answer for homes where adding or extending ductwork would be difficult.

Replacing a Furnace? Know the Air District Rules
The Bay Area Air District has adopted rules that affect future furnace choices. 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.
These rules do not require you to replace working equipment. They apply only when an existing furnace fails or is replaced. If your current furnace is running well, we can keep it maintained and repaired. If it's aging, it may make sense to think about your options now rather than during an emergency, so you're not choosing a system in a hurry on a cold night.
Heat Pumps, Mini-Splits, and Incentives
Heat pumps provide both heating and cooling from one system, which suits a climate where winters are mild and summers can get warm. Ductless mini-splits use the same technology without needing ductwork, which can help in hillside homes with limited attic or crawlspace access.
On costs, there is one change to note: the federal Energy Efficient Home Improvement Credit (25C) covered qualifying heat pumps placed in service before December 31, 2025, and 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 any quote.
