We just purchased and had installed a Carrier Heat Pump from Affordable Heating and Air. Our air conditioner stopped working totally. We changed from a gas furnace/electric air conditioner to the Carrier Electric Heat Pump.
The Senior Advisor, Allen B was so helpful in options and different brands. He made our decision so much easier. I went with Affordable Heating and Air initially because of their outstanding online reviews. Their price was very, very good, and we quickly decided on them.
From detailed sales and product information (Allen B) to incredible installation team (Estanley and Frank) to phone consults and rebate help, the entire process has been very easy and comforting. Jeremiah B. from the office ws very helpful in rebate process.
They are Professional!
Thank you Affordable Heating and Air!

Juan was very helpful when giving us our estimate. I have never seen someone so happy and enthusiastic to help the customer as Juan was. He didn't pressure one way or the other; he just gave options and his informed opinion. He was thorough in his estimate, including crawling up into our attic and taking pictures of all the ducts. I one hundred percent recommend.

I found them on Facebook over a weekend, and they took care of my air conditioner that broke down in 115-degree heat. On top of that, Jeremy educated me on how to take care of my air conditioner and the blower. I saved their number, and they will be the first ones I reach out to for my cooling and heating needs. Best part they are fair and affordable as their name says.

Affordable H&A replaced my 33 year old ducting. They came out the day after I contacted them and went over what they thought should be done, providing me with a quote. It was 19% and 34% less than other quotes (with the same work proposed). A week later the installation folks completed the work in about 6 hours. They carefully screened off the closet where they had access to the attic and lay tarps to not mark my floors. After they stripped out the old ducts they showed me how they were going to build a new box on the furnace and where the new ducting would be routed. They kept me informed each step of the process which was nice to learn what and how the work was done. One item on the estimate was not needed and they promptly credited the money I paid for that item.

In the photos you can see the shiny new ducts and the old gray ducting that was failing in some places and which had been modified by prior homeowners. Photos also how the closet was masked off to keep everything clean.

I give them a 5-star review and definitely recommend their work and communication.

I started the research for a new AC unit six months prior, and I spoke with about two dozen different vendors. The Tech from Affordable Heating and Air was very thorough when he did the site survey. Their pricing was the best and they offered a price match guarantee. The Installation Techs showed up on time and completed the install before 5PM PST. They cleaned up the entire area when they were done. I can say that I was really pleased with the quality of their work. I was pleased with the price for the new unit. They were all pretty friendly, and made everything easy. I would recommend them to anyone who needs a new AC unit! They can feel to use me as a reference any time!

This company is amazing! I don't even know where to begin. For starters, they do more than just Heating and Air. They also do roofing and home remodeling. We had an issue with our roof during some severe rainstorms and in the middle of it our furnace died. Edward from the company came out to inspect the furnace, and while he was here we mentioned the roofing issues we were having not knowing this company also does roofing. Edward spent 2 hours inspecting our furnace and the roof and went above and beyond. He was very thorough in diagnosing our issues and took his time talking and explaining to us what was going on. At the moment that I am writing this review we are currently in the works with an insurance claim to help cover the cost of all the repairs. And this company has been amazing helping us get what we need from insurance. I am very grateful for Edward and this company. And I can't wait to see how everything turns out when they are through with all of the repairs.
Hire this company! Don't question it! They know what they are doing and their customer service is truly top notch.

Javier came within a few hours to fix a broken furnace. He spent a lot of time going over every potential problem and isolating the source. He did a great job of explaining every step he took and gave honest thorough options for what to do. Cannot recommend higher.
We recently got 3 mini split units from Affordable Heating and Air. It was a seamless experience from start to finish. Easy quoting, best price( we got 4 different quotes from different companies), all staff was polite and helpful. From customer service, installers to service call, all very professional. We just had Jeremy Russel come out today on Christmas Day, we were so grateful. He did his due diligence and throughly inspected and everything was good. Upon requesting the service call customer service worked promptly to get us someone out her even during the holiday. Thank you Jeremy!

The installation of my HVAC system went well, but follow-up wasn't very good. I paid what I thought was a bit too high a price, $11,000 for an 800-square-foot home, but I can live with that. After the installation, which included having an installer crawl around under my house, I had two new problems: a dead animal smell coming out from under the house, and the water coming out from my kitchen faucet had been reduced to a trickle. I had the company send someone out, but had to pay for a service call. The service call was not helpful at all. The technician reported that it seemed like a "plumbing smell," and as far as the trickle coming out of the kitchen faucet, he gave me some line of unhelpful nonsense about how I'd have to basically become a plumber and deal with it myself. I am still living with the faucet problem — I'll attach a photo showing the water coming out at FULL STRENGTH. As far as the dead animal smell, of course that's exactly what it was, not a "plumbing smell." It was a big dead cat that, maybe just by coincidence, appeared under my house just after the installers were working there. I'll also try to attach a picture of the dead cat, but I had to pay to have someone else come out to find and remove the cat. So I keep shelling out extra money after the installation, and I still don't have my kitchen back working the way it was before.
The mini split in my unit wasn’t working properly. AC worked fine, but heat wasn’t working and I consistently received error codes when the unit was in heating mode. Juan promptly arrived to fix the until. He was friendly, professional and knowledgeable. He took his time to examine and assess the issue and fixed it. He cleaned the filters and even stayed for a while to ensure the unit remained working properly. Highly recommend Juan Gongora. He’s the best.

I had brand new heating and air installed in my condo two weeks ago. It would be amazing if spending this much money came without a hitch, but that just wouldn’t be reality with something as complex as a whole new system in a home that hasn’t had both heating and air in it before. But I will say that Affordable did everything in their power to make sure their promises were met. They never promised that there wouldn’t be issues, just that they would make them right if any came up, and it was possible to do so. The installers for my job, Rogelio, Rigoberto and Bryan were excellent. They are hardworking, reliable, and professional. They listened to my concerns and did everything to address them. I knew I was going to buy a system one way or another, but I am glad I went with Affordable.

Why Smart LA Homeowners Switch to Ductless Mini-Split AC Systems?

Los Angeles’ diverse homes and microclimates demand smart cooling solutions – and ductless mini-splits rise to the challenge. Here’s why they’re becoming the go-to choice across LA County:

1. Perfect for LA's Unique Homes

No ductwork? No problem. Whether you’re in: 

  • Historic Pasadena bungalow. 
  • Santa Monica beach cottage. 
  • Echo Park ADU. 
  • Modern downtown loft. 

Mini-splits deliver powerful comfort without costly renovations or compromising architectural integrity.

2. Customized Comfort Room by Room

Set different temperatures in every space:

→ Keep your home office in Burbank cool while the bedroom stays warm. 

→ Comfortably convert that garage or attic. 

→ Only pay for the space you’re using.

Learn which rooms benefit most from zoned cooling in LA homes.

3. More Energy Savings

  • 30-40% more efficient than traditional AC. 
  • SEER ratings up to 30+ (qualifying for CA rebates). 
  • No duct losses = no wasted energy.

4. Quick, Clean Installation

Most systems are installed in 1-2 days with: 

  • Minimal disruption  
  • No wall/ceiling demolition  
  • Flexible placement options 

5. Library-Quiet Operation

At 19-40 decibels, you’ll forget it’s running – perfect for: 

  • Nurseries  
  • Home theaters  
  • Bedrooms 

6. Future-Proof & Eco-Friendly

  • Meet California’s strict environmental standards. 
  • Use advanced, low-GWP refrigerants. 
  • Easy to expand as your needs change.

7. Cost-effective Comfort

More affordable with rebates and incentives:

    • Single-zone: $2,000-$6,000  
    • Multi-zone: $3,200-$10,500 

8. Advanced Features for Modern Comfort

Modern mini-split systems use inverter technology. This technology adjusts compressor speed for precise temperature control and energy savings.
Many models offer smart controls. You can operate your system with Wi-Fi, smartphone apps, or voice assistants.
Advanced filtration options are available. These include HEPA and ionizing filters. These filters help reduce allergens and improve indoor air quality.
These features benefit tech-savvy users and those with allergies.

From century-old craftsman homes to sleek modern builds, ductless mini-splits deliver personalized comfort that makes sense for LA’s climate and lifestyles.

Common Myths About Mini-Splits-DEBUNKED (With Data-Driven Facts)

Myth 1: Mini-splits don't cool large spaces evenly.

Fact: These modern systems deliver even airflow when sized and placed correctly.

Key Stat: Properly installed mini-splits maintain ±1°F temperature variance across rooms.

LA Tip: Our certified technicians perform load calculations to match units to your home’s square footage, insulation, and sun exposure.

Myth 2: They’re too noisy for apartments or offices.

Fact: New models operate between 19 and 32 decibels, making them quieter than whispers.

Comparison: Window ACs hit 50–60 dB, while mini-splits run below the level of refrigerator noise.

Myth 3: They're Too Expensive.

Fact: While upfront costs may be higher, mini-splits deliver significant long-term savings. With energy costs up to 60% lower than traditional systems and reduced maintenance requirements, the total cost of ownership is often lower.

Myth 4: Mini-Splits Can’t Cool or Heat the Whole House

Fact: These multi-zone mini-split systems heat and cool every room as effectively as central air. Each indoor unit is independently controlled so that you can set different temperatures in each area, eliminating hot and cold spots.

Myth 5: They're Only for New Construction.

Fact: Mini-splits are ideal for retrofitting existing homes, particularly in LA’s older neighborhoods where installing ductwork would be invasive and costly. They suit home additions, garage conversions, or upgrading outdated heating systems.

Avoid Mini-Split AC Installation Mistakes in Los Angeles County

Installing a mini-split AC system in Los Angeles County isn’t as simple as mounting a unit and calling it a day. Between the region’s microclimates, diverse architecture, and strict permitting rules, even small installation errors can lead to inefficiency, breakdowns, or costly repairs.

Learn how to avoid common mistakes and sustain optimal system performance year after year.

1. Smart Placement for Maximum Efficiency.

Indoor Unit Placement:

  • Mount indoor units 7–8 feet high on an interior wall for even air distribution.
  • Avoid placing units too high (which causes warm air to pool) or too low (leading to short cycling and uneven cooling).
  • Keep units clear of large furniture and obstructions to maintain airflow.

Outdoor Unit Placement:

  • Ensure 12–24 inches of clearance on all sides for proper airflow and easy maintenance.
  • Do not install near heat sources, such as dryer vents, grills, or in direct sunlight.
  • Elevate the unit to prevent debris buildup and flooding during heavy rains.

Tip:

Clever placement enhances efficiency, lowers energy costs, and prolongs system life. Always consult a professional for optimal results.

2. Right-Sizing for LA’s Microclimates.

  • Oversized mini-split units cycle frequently. This causes wear and lowers efficiency.
  • Undersized units run nonstop. This raises energy bills and fails to cool rooms.
  • Perform a Manual J load calculation. This calculation uses insulation, window exposure, occupancy, and usage, not just square footage.
  • Correct sizing gives reliable comfort in all LA microclimates.

Tip:

Share room sizes, window counts, and recent renovations with your installer for accurate sizing.

3. Easy Access to Maintenance

  • Leave 30″ clearance for technicians. 
  • Labeling wiring—no one wants to play “guess the circuit” later.

4. Secure Mounting for Older LA Homes.

  • Older Los Angeles homes require careful mini-split installation.
  • We reinforce walls to support the unit’s weight and use vibration pads to reduce noise.
  • Multiple anchors keep units secure during earthquakes.
  • Our team uses minimally invasive methods to protect your home’s original structure and style.

5. Refrigerant Lines Done Right.

  • Keep running under 50 feet (longer lines reduce efficiency). 
  • Limit elevation changes (max 25 feet between indoor/outdoor units). 
  • Protect lines with UV-resistant covers—essential for sun-drenched yards and high-traffic areas.

6. Electrical & Drainage: LA Code Requirements.

Electrical: 

  • A dedicated circuit is required (no daisy-chaining!).
  • Permits & inspections are mandatory. LA County doesn’t cut corners. 

Drainage: 

    • Slope condensed lines 1/4″ per foot to prevent leaks. 
    • Add a condensate pump and algae tablets to humid zones (like the South Bay).

7. Airflow and Indoor Air Quality in Open LA Spaces

  • Keep 6–8 feet of clearance for indoor units.
  • Do not direct airflow at seating areas to avoid discomfort.
  • In open homes, ducted mini-splits improve comfort and air circulation.
  • Choose models with advanced filtration for improved indoor air quality, which helps alleviate symptoms for allergy and asthma sufferers.

Pro Tip: Permits Are Non-Negotiable.

Do not install mini-splits yourself. Los Angeles County requires permits and licensed HVAC contractors for installations. Only professionals can handle refrigerant and electrical work safely. We use eco-friendly refrigerants and follow strict safety standards to protect your home and the environment.

 

From Santa Monica’s salty air to the San Fernando Valley’s heat waves, a well-installed mini-split keeps your home comfortable year-round. By nailing placement, sizing, and code compliance upfront, you’ll avoid headaches and enjoy efficient cooling, no matter where you are in LA.

Not sure whether to repair or replace your current unit? Read our guide on when to repair or replace a heat pump in Los Angeles homes to weigh your options.

Comparing Ductless Mini-Split, Central Air Conditioner, and Window AC: Features and Benefits

Choosing the right cooling system depends on your home’s needs, budget, and installation requirements. The table below compares ductless mini-splits, central air conditioners, and window AC units across key features such as installation, cost, efficiency, noise, heating, lifespan, filtration, and best use cases. Use this side-by-side guide to make an informed decision for your space.

FeatureDuctless Mini-SplitCentral ACWindow AC
Ductwork NeededNoYesNo

Air FiltrationBasic to moderate (some premium models offer advanced)Advanced options (HEPA, UV, etc.)Basic (minimal filtration)
Best ForHomes without ducts, Older homes, room additions, zoning, energy efficiencyWhole-home cooling (with existing ducts)Single rooms, rentals, temporary use

Ductless mini-split systems are quiet, energy-efficient, and easy to install without ductwork; however, they have a higher upfront cost—especially for whole-home solutions. Central air is more affordable if ducts are already in place and offer advanced air filtration, but it is less efficient due to duct losses and provides less flexible room-by-room control.
