Jason Trent isn’t an absentee owner. He holds the title of Field Supervisor and stays physically present on job sites, which means the person accountable for your repair is the same person checking refrigerant pressures and duct connections.

Our AC Repair & Installation Services in Citrus
AC Repair
Citrus’s combination of Santa Ana wind heat spikes and 140°F+ attic temperatures destroys capacitors and overloads compressors faster than in flat-valley neighborhoods. We diagnose the real failure, not just swap the obvious part. A typical AC repair in Citrus runs $150–$650. We carry capacitors, contactors, and refrigerant for same-day resolution on most calls.
AC Installation
New AC installation in Citrus demands precise load calculation because of that sharp diurnal swing, mountain drainage winds, and the wild card of wildfire smoke filtration needs. We size for both peak cooling and unexpected heating demand, since winter nights along the foothills stress systems that were originally specified for cooling only. Installation ranges from $3,500–$7,500. Every job includes proper permitting through LA County, which we handle start to finish.
AC Replacement
Replacing a system in a 1960s ranch near Citrus Avenue often means dealing with original flex ductwork that’s crimped, unclamped, and bleeding conditioned air into a 145°F attic. We don’t just drop in new equipment. We inspect the full distribution path and quote duct remediation when it’ll save you 30% or more on your cooling bill.
Refrigerant Recharge
Low refrigerant in Citrus usually signals a leak, not normal consumption. The thermal cycling from 100°F days to 50°F nights stresses coil joints and flare connections. We leak-test with electronic detectors and nitrogen pressure testing, then recharge to factory specification. Band-aid top-offs without leak repair are a waste of your money.

Common AC Repair & Installation Problems We See in Citrus Homes
- Original 1960s flex duct crimped and unclamped. The citrus-grove subdivision boom produced homes with thin flex duct draped over joists, baking in 145°F attics. We’ve measured 35% cooling loss before air reaches the vent. Replacement with insulated, clamped R-8 ductwork fixes it permanently.
- Systems undersized for heating. Original equipment was specified for cooling loads only. When foothills winter nights drop into the 30s, heat exchangers on undersized furnaces crack from overwork. We see this annually on service calls after the first cold snap.
- Santa Ana wind compressor damage. The mountain geography funnels hot, dry winds directly through Citrus, spiking head pressures and accelerating wear on outdoor units. Compressors that should last 12–15 years sometimes fail in 8.
- Wildfire smoke infiltration. Smoke from the Angeles National Forest channels directly into Citrus during fire season, overwhelming standard filters and coating evaporator coils. We install MERV 13+ filtration and recommend coil cleaning protocols specific to smoke exposure.

FAQs — AC Repair & Installation in Citrus
Your ductwork is likely the culprit. In Citrus’s 1960s ranch homes, original flex duct in 145°F attics cracks, crimps, and disconnects, losing a third of cooling before air reaches your vents. A tune-up cleans and calibrates the equipment, but it can’t fix distribution. We inspect attic ductwork with every service call and quote remediation when the numbers justify it. Call (855) 467-1888 for a free estimate.
Yes. Because Citrus is unincorporated Los Angeles County, all HVAC permits and inspections route through the county building department, not a city hall. Out-of-area contractors frequently mishandle this workflow, causing delays and failed inspections. We process county permits for every replacement and know the specific inspector requirements. Jason Trent personally verifies permit closure before we consider a job complete.
They spike operating pressures and accelerate compressor wear. Citrus’s mountain-channel geography funnels hot, dry Santa Ana winds directly through the community, pushing condensing temperatures higher than flat-valley locations. That extra thermal load shortens compressor life and increases refrigerant leak risk at flare joints. We account for this in our load calculations and recommend hard-start kits and pressure-monitoring on older systems.
Yes, particularly for managing Citrus’s sharp day-night temperature swings. A programmable or Wi-Fi thermostat can setback cooling during mountain drainage wind hours and pre-cool before Santa Ana conditions peak, reducing compressor runtime stress. We install and configure smart thermostats matched to your specific equipment brand. They’re not universal, so we verify compatibility before recommending a model.
We service and install Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. Our technicians are factory-trained or field-experienced across all nine, so we don’t turn away jobs with “we don’t work on that brand.” We stock common repair parts for Carrier, Trane, and Lennox locally for fastest turnaround. Call (855) 467-1888 to confirm parts availability for your specific model.
On a July afternoon, we serviced a 1960s ranch home near Citrus Avenue where the original flex duct in the 145°F attic had crimped at every bend, losing a third of cooling. We replaced the ductwork with insulated, clamped R-8 lines and installed a properly sized Trane system to handle the foothills’ 100°F+ days and sharp night drops.
