Air Conditioning Services
When temperatures climb in Chatsworth, a dependable cooling system isn’t optional. Our team handles AC repair, installation, and full replacement, making sure homes stay efficient and comfortable through the peak of summer. Many properties near De Soto Avenue and Nordhoff Street still rely on aging units, and upgrading to a high-efficiency system can lower utility bills while improving indoor comfort.
Chatsworth AC Repair
When your cooling system goes down during a Valley heatwave, waiting isn’t an option. Our Chatsworth technicians respond quickly to diagnose and repair air conditioners of every make and model, including older systems still common in ranch-style homes. Whether it’s a unit blowing warm air on Devonshire Street or a noisy compressor in Twin Lakes, we bring the tools and parts needed to restore comfort on the first visit.
Common repairs include refrigerant leaks, faulty capacitors, clogged drain lines, and frozen coils. Because Chatsworth summers are long and hot, these issues often appear more frequently than in milder climates. Fast repairs not only restore comfort but also prevent small problems from causing costly breakdowns.
AC Installation and Replacement
For homeowners in neighborhoods like Porter Ranch and Northridge, replacing an outdated air conditioner with a modern, high-efficiency model can mean lower bills and better cooling power. Our installation process starts with a load calculation that accounts for Chatsworth’s climate, your home’s square footage, insulation levels, and ductwork condition. This ensures the new system isn’t undersized or oversized — both of which shorten lifespan and waste energy.
We install central AC systems, heat pumps, and ductless mini-splits depending on what works best for the home. Many Chatsworth houses built in the 1960s and 70s still rely on older ductwork, so we inspect and recommend updates when necessary to get the most from a new system.
AC Tune-Ups and Inspections
Regular tune-ups are critical in Chatsworth, where air conditioners run almost nonstop during summer. Our seasonal maintenance includes coil cleaning, refrigerant checks, airflow testing, thermostat calibration, and electrical inspections. Homeowners near Mason Avenue or Nordhoff Street often schedule spring tune-ups to prepare for summer, and again in fall to catch issues after heavy use.
A well-maintained system lasts longer, performs better during heat waves, and keeps energy costs manageable. Maintenance also helps improve indoor air quality — an important consideration in the Valley, where dust and wildfire smoke often affect homes.
Heating Services for Chatsworth Homes
Furnace Repair and Installation
Many Chatsworth homes still rely on traditional gas furnaces. When a furnace fails on a cold Valley night, our team provides quick repairs to restore heat safely. From pilot light issues to blower motor failures, we handle every problem with licensed expertise.
When replacement is the smarter option, we install high-efficiency furnaces that keep families warm while lowering utility costs. Homeowners in Winnetka and West Hills often choose modern furnaces to replace units that have been in service for decades.
Boilers & Radiant Heating
Some Chatsworth homes rely on boilers or hydronic heating systems, including radiant floor setups. Our technicians provide inspections, repairs, and ongoing maintenance to keep these systems operating safely and efficiently. While we do not install new radiant systems, we ensure existing equipment continues to perform reliably for Valley homeowners.
Heat Pumps for Mild Winters
Because Chatsworth winters are relatively mild, heat pumps are an excellent solution for both heating and cooling. We repair and install heat pumps designed to provide efficient comfort all year long. This is a popular choice in neighborhoods like Twin Lakes, where homeowners appreciate the energy savings of a single system that handles both functions.
Chatsworth Ductless Mini-Split System Experts
Not every home in Chatsworth was built with ductwork, and many families want a flexible option that can cool and heat specific rooms without running a full central system. Ductless mini-splits are ideal for older ranch-style houses, room additions, and converted garages common across the Valley. These systems provide zoned comfort, letting you control temperatures in individual spaces while keeping energy costs down.
Our team installs and services ductless units sized for Chatsworth’s climate, and we help homeowners take advantage of available rebates through LADWP and Southern California Edison. Whether you need a single room solution or a whole-home ductless system, we make sure it’s installed for maximum efficiency and long-term performance.
Ductwork & Insulation Services
Leaky ducts and poor insulation are leading causes of high energy bills in Chatsworth homes. We provide duct sealing, full replacements, and attic insulation upgrades to reduce wasted energy and improve comfort. These upgrades are especially important for homes built decades ago, where original ductwork and insulation no longer meet today’s efficiency standards.
We provide:
Professional Duct Sealing & Replacement to eliminate leaks and improve airflow
Blown-In Insulation installation to reduce heating and cooling loss year-round
Our team inspects, upgrades, and protects your home’s efficiency—so your HVAC system doesn’t have to work harder than it should.
