We’ve been driving to Sunnyvale from Los Angeles for years, and we know the difference between a quick capacitor swap on a newer system and the full-day retrofits that older homes demand. Anthony Moreno, our founder and lead installer, still carries his tools on every job. That means when you call Meridian Heating & Air, the person quoting your work is the same person climbing into your attic or running your refrigerant lines. No handoffs to subcontractors, no surprises when the crew shows up.
Sunnyvale’s heat has changed. The September Diablo winds now push temperatures past 100°F, and those 1960s slab-foundation ranches near Evelyn Avenue or along the Sunnyvale-Saratoga Road corridor were never built for it. We’re the AC Repair & Installation crew that understands what “no existing ductwork” actually means for your timeline and your budget.
Why Meridian Heating & Air Los Angeles Is Sunnyvale’s Preferred AC Repair & Installation Company
Nearly two decades of hands-on HVAC experience. Anthony Moreno founded this company 19 years ago and still serves as lead installer. In Sunnyvale, that matters because the jobs here aren’t plug-and-play. Slab foundations, original floor furnaces, and Title 24 HERS requirements turn what looks simple into something that demands real field judgment.
286 customers and counting. Our reviews average 4.8 stars across those 286 verified jobs, and Sunnyvale homeowners specifically mention appreciating that Anthony shows up on the job, not a rotating crew of strangers. One recent review from a 94087 customer noted we completed a full duct system install in one trip after another company had quoted three separate visits.
We work on your brand. Factory-trained or experienced on Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. That breadth matters in Sunnyvale, where we see everything from original 1970s Rheem gas furnaces to newer Trane heat pumps in teardown rebuilds.
From routine tune-ups to emergency calls. Our emergency HVAC service is available for urgent situations, and we understand Sunnyvale’s geography. The acreage properties near Stevens Creek and the foothills have longer service drives and often need separate cooling zones for detached workshops. We plan for that before we leave Los Angeles, not after we arrive.
Our AC Repair & Installation Services in Sunnyvale
AC Repair
Sunnyvale’s late-summer heat spikes stress capacitors and compressors hard. We see a lot of failed run capacitors in September when systems that ran fine in July suddenly can’t start against 100°F afternoons. Most AC repair calls in Sunnyvale fall between $150–$650, and we stock common parts for Trane, Lennox, Goodman, and Rheem to avoid delays. If your system’s down, call (877) 454-5066 — we’ll diagnose it straight and fix what actually needs fixing.
AC Installation
This is where Sunnyvale gets interesting. Those 1,100–1,600 sq ft slab-on-grade ranches in 94086 and 94087 were built for Lockheed workers with no cooling and minimal heat. Adding AC means either attic duct runs or ductless mini-splits, and every job triggers California Title 24 HERS duct leakage testing. We recently handled an AC installation on a 1960s ranch near Evelyn Avenue in zip 94087. The homeowner’s original floor furnace had no ductwork, so we designed and installed a full duct system with a Trane heat pump, all under Title 24 HERS duct leakage testing, completing the job in one trip with no surprises. That’s the difference when the founder runs the install himself.
AC Replacement
Replacing an existing AC in Sunnyvale sounds straightforward until you realize the old system was sized for a 1960s home with single-pane windows and no insulation upgrades. Post-2000 teardown rebuilds and ADU additions in these same neighborhoods create mixed-vintage systems that complicate equipment sizing and permitting. We measure properly, check your actual load, and make sure the new equipment matches your house as it exists today, not as it was built in 1962.
Refrigerant Recharge
Low refrigerant means a leak, period. In Sunnyvale’s inland climate, where the marine layer barely reaches and summer run hours are long, even a small leak adds up fast. We find and fix the source, then recharge to factory spec. No topping off and hoping. R-410A and newer R-32 systems both, depending on your equipment age.

Trusted Brands We Service in Sunnyvale
We carry parts and full systems for Trane, Lennox, Goodman, and Rheem, with access to the full nine-brand lineup when needed. For Sunnyvale’s climate — hot, dry late summers and mild winters — we often recommend Trane heat pumps or Lennox variable-speed systems that handle the load without oversizing. Goodman and Rheem remain solid choices for budget-conscious replacements where the ductwork already exists. We don’t push one brand because we’re not tied to one supplier. We pick what fits your house, your usage, and your existing infrastructure.
Common AC Repair & Installation Problems We See in Sunnyvale Homes
- Underestimating the scope from floor furnace to full ductwork. Homeowners expect a simple swap, but slab foundations force attic runs or mini-splits. We quote the real job, not the fantasy version.
- Skipping HERS testing to save time. California Title 24 requires duct leakage verification, and failing it means rework. We build the test into our process from day one.
- Using standard residential openers on oversized workshop doors. Heavy-duty openers and springs are mandatory for detached garages on acreage properties near Stevens Creek. We spec and install them.
- Sizing new equipment for the original 1960s envelope. Homes with added insulation, new windows, or ADUs need fresh load calculations. We run them.

FAQs — AC Repair & Installation in Sunnyvale
Slab foundations eliminate crawl space access, so ductwork must run through attics or walls, and every installation requires California Title 24 HERS duct leakage testing that adds labor and inspection steps. The original homes were built with floor furnaces and zero cooling infrastructure, so you’re paying for complete system design, not just equipment replacement. Call (877) 454-5066 for a free estimate that breaks out exactly what your home needs.
Yes, ductless mini-splits are often the most practical path for Sunnyvale’s slab-foundation ranches, especially when preserving the existing floor furnace for occasional heating. We size the mini-split for your actual cooling load, not the original 1960s envelope, and we make sure the outdoor unit placement works with your property lines and any detached workshop structures. Call (877) 454-5066 to discuss whether a mini-split or full ducted system fits your situation.
Yes, we spec and install heavy-duty openers and springs for oversized doors on detached workshops, which we encounter regularly on Sunnyvale’s acreage properties near Stevens Creek and the foothills. Standard residential openers will fail prematurely on these doors. We measure the door weight and cycle requirements, then install equipment rated for the actual load. Call (877) 454-5066 to schedule an assessment.
Trane and Lennox heat pumps handle Sunnyvale’s hot, dry late summers and mild winters efficiently, while Goodman and Rheem offer reliable value for straightforward replacements. We don’t limit you to one brand — we work on nine major manufacturers and recommend based on your existing infrastructure, budget, and whether your home has ductwork or needs a mini-split solution. Call (877) 454-5066 and we’ll talk through what makes sense for your specific setup.
Diablo winds push Sunnyvale temperatures past 100°F in September, forcing AC systems to run at maximum capacity for extended periods when they’re already fatigued from a full summer. This is when we see the most compressor failures and capacitor blowouts, especially on systems that were marginally sized or poorly maintained. A pre-season tune-up ($80–$200) catches most of these issues before the heat hits. Call (877) 454-5066 to schedule yours.
