Your AC should work when temperatures hit triple digits. Not struggle. Not quit halfway through summer. Not cost you a fortune in energy bills because it’s running inefficiently.
When your system is installed correctly and maintained properly, you get consistent cooling throughout your home. Your energy bills stay manageable even with California’s electricity rates running 88% higher than the national average. You sleep through the night without waking up hot. Your family stays comfortable during heat waves that push past 105 degrees.
That’s what professional AC services deliver. Not just a working unit, but reliable performance that lasts 15-20 years. You’re not calling for emergency repairs every summer or wondering if your system will make it through another heat wave. You have confidence in your equipment because it was sized right, installed right, and maintained by an HVAC company that knows California’s climate demands.
Hot & Cold HVAC serves homeowners throughout Westlake and surrounding California communities. Our team includes licensed, certified technicians who handle everything from emergency AC repairs to complete system installations.
What sets us apart is straightforward service without the sales pitch. When you call, you get an honest assessment of what your system needs—not an upsell to equipment you don’t need. Pricing is transparent and provided upfront. No hidden fees. No surprises when the work is done.
We work with industry-trusted brands like Carrier, Daikin, Rheem, Trane, and Lennox. Every installation includes proper permits, inspections, and compliance with local building codes. That protects your investment and ensures your warranty stays valid.
Your service starts with an honest assessment. Our technician evaluates your current system, checks your home’s cooling needs, and discusses what’s actually happening with your equipment. If it’s a repair, you’ll know what’s wrong and what it costs before any work begins. If it’s a new installation, you’ll get recommendations based on your home’s size, layout, and budget—not a sales pitch.
Once you approve the work, we handle the details. For repairs, our trucks are stocked with common parts so most jobs finish the same day. For installations, our crew schedules around your availability, protects your home during work, and cleans up completely when finished.
The actual work is efficient. Repairs typically wrap up in a few hours. New AC installations usually take one full day for straightforward replacements. More complex jobs requiring ductwork modifications or electrical upgrades might extend to two days, but you’ll know the timeline upfront.
After the work is complete, our technician walks you through everything. How to operate your system. When to change filters. What to watch for. You’ll have direct contact information for any questions that come up later. The goal is to make sure you understand your equipment and feel confident it’ll work when you need it.

Your AC service includes professional diagnostics, transparent pricing, and work performed by licensed technicians. For repairs, that means identifying the actual problem—not just symptoms—and fixing it with quality parts. For installations, it means proper system sizing through load calculations, not guesswork. Your new equipment is matched to your home’s specific cooling demands.
In Westlake’s climate, that matters more than you’d think. Summers regularly push past 100 degrees. Winters drop into the 40s. Your HVAC system handles both extremes, and it needs to be sized correctly to do that efficiently. Oversized systems cycle on and off constantly, wasting energy and failing to control humidity. Undersized systems run nonstop, struggle to maintain temperature, and wear out faster.
The area’s air quality adds another layer. Wildfire smoke and pollen are seasonal realities here. Proper filtration isn’t optional—it’s essential for keeping your indoor air breathable. Service includes recommendations for MERV 13+ filters or whole-home air purification systems that actually address smoke particles and allergens.
Every installation comes with permit handling and inspections. California has specific codes for HVAC work, and cutting corners creates problems down the line. Proper permitting protects your home value, keeps your warranty valid, and ensures the work meets safety standards. You also qualify for California’s energy efficiency rebates—up to $8,000 for income-qualified homeowners, up to $4,000 for middle-income families, plus federal tax credits for ENERGY STAR systems.
AC installation in Westlake typically runs $5,000 to $13,000 for central air systems. Mini-split installations usually cost $8,000 to $15,000 depending on how many zones you’re cooling. The final price depends on your home’s size, the system type you choose, and installation complexity.
Higher-efficiency systems cost more upfront but save you money long-term. With California’s electricity rates 88% above the national average, an efficient system can save $500+ annually on energy bills. That adds up over a 15-20 year lifespan.
You’ll get a detailed quote before any work starts. No hidden fees. No surprise charges. The estimate breaks down equipment costs, labor, and any additional work like ductwork modifications or electrical upgrades. Many homeowners also qualify for California rebates and federal tax credits that can cover a substantial portion of the installation cost.
Most AC installations in Westlake take one full day for straightforward replacements where existing ductwork is in good condition. Simple mini-split installations often finish in 4-6 hours. More complex central air installations may require 8-10 hours depending on your home’s specific needs.
If your installation requires electrical upgrades, extensive ductwork modifications, or other complexities, it might extend to two days. Our technician will give you a realistic timeline during your consultation so you can plan accordingly.
Westlake’s mild climate means weather delays are rare. Installations can usually stick to scheduled dates. Our crew arrives on time, works efficiently, and cleans up thoroughly before leaving. You’ll have reliable cooling restored quickly—especially important during peak summer months when temperatures regularly exceed 100 degrees.
The right AC size depends on your home’s square footage, insulation quality, ceiling height, window placement, and local climate conditions. Most Westlake homes need 1 ton of cooling capacity per 400-600 square feet, but proper sizing requires professional calculation—not rules of thumb.
An oversized system cycles on and off frequently, wasting energy and failing to control humidity properly. An undersized system runs constantly, struggles to maintain comfort during heat waves, and wears out faster. Both scenarios cost you money and comfort.
Professional load calculations account for your home’s unique characteristics. How much sun hits your windows. How well your attic is insulated. How your home is oriented. These factors significantly impact cooling needs. The calculation ensures your system runs efficiently without working harder than necessary. That means lower energy bills, better comfort, and a longer equipment lifespan.
Yes, AC installation in Westlake requires proper permits and inspections to ensure safety and code compliance. This isn’t just bureaucracy—permits ensure your installation meets California’s building codes and safety standards.
We handle all permit applications and coordinate required inspections as part of our service. You don’t have to deal with the paperwork or scheduling. The work is done to code, which protects your investment and ensures your warranty remains valid.
Proper permitting also matters if you ever sell your home. Unpermitted work can create complications during home inspections and potentially affect your home’s value. When everything is done correctly with proper permits, you have documentation that the work meets all requirements. That gives you peace of mind and protects your investment for years to come.
Most HVAC systems in Westlake should be serviced at least once a year. Ideally, schedule AC maintenance in spring before summer heat arrives, and heating maintenance in fall before winter. This ensures your equipment is ready when you need it most.
Regular maintenance catches small issues before they become expensive repairs. Our technicians clean coils, check refrigerant levels, inspect electrical connections, and test system performance. We identify worn parts that need replacement and address efficiency problems that drive up energy bills.
In Westlake’s climate, where systems run hard during 100+ degree summers, maintenance is especially important. Neglected systems work harder, use more energy, and fail more often. A well-maintained system runs efficiently, lasts longer, and breaks down less frequently. That saves you money on both energy bills and emergency repairs. Most systems last 15-20 years with proper maintenance, but neglected equipment often fails much sooner.
Yes, we provide same-day and emergency AC repair services because AC failures during Westlake heat waves aren’t just uncomfortable—they can be dangerous when temperatures exceed 105 degrees. We keep technicians and equipment ready during peak summer months specifically for these situations.
When you call for emergency service, you’ll speak with someone who can dispatch a technician quickly. Our service trucks are fully stocked with common parts so most repairs can be completed the same visit. You’re not waiting days for parts to arrive while your home heats up.
Emergency service may cost slightly more than scheduled appointments, but reliable cooling shouldn’t wait when extreme heat becomes a health concern. The focus is getting your system running again as quickly as possible so your family stays safe and comfortable. Evening and weekend emergency service is available during heat advisories when you need it most.
