Coldharbour Heating & Air is the HVAC company Walnut Park homeowners call when a flat-roofed stucco bungalow needs cooling that actually works or a 1940s floor furnace finally gives out. Most HVAC work in Walnut Park costs between $150 and $7,500 depending on whether it’s a repair or a full system replacement, and we quote the real number before any tool leaves the truck. Walnut Park’s tight mechanical closets, shallow roof cavities, and aging ductwork make this neighborhood its own kind of job. Call (213) 531-5904 and a live person answers, day or night.
Why Walnut Park Homes Are Different
Walk down any street in Walnut Park and you’ll see the pattern: small single-story stucco houses and duplexes built between the 1920s and 1950s, most with flat or low-slope roofs and barely any attic to speak of. That changes how HVAC work gets done here. A standard high-efficiency system with full-size ducting often won’t fit in these homes because there’s nowhere to run it. So our technicians regularly design compact ductless or low-profile systems that squeeze into tight mechanical closets and shallow roof cavities without ripping out ceilings or closets.
There’s another wrinkle specific to Walnut Park. Many of these older houses still have their original floor furnaces, and a lot of the ductwork wrapped around them carries asbestos insulation. Before we touch a retrofit, we check for it. The city’s seismic retrofit rules also come into play when a rooftop unit needs new supports or strapping. None of this makes the job impossible, but it does mean the cheap, one-size-fits-all approach doesn’t survive contact with a 1930s Walnut Park bungalow. You need a technician who has seen this housing stock before.
Styles & brands we work with
Our Main Walnut Park Services
Three jobs dominate the calls we get from Walnut Park homeowners: AC repair when a condenser quits during a heat wave, furnace repair when a floor furnace or wall heater acts up in January, and AC installation when an older system can’t keep up and the time comes to replace it.
AC Repair in Walnut Park
Walnut Park’s marine layer rolls in most mornings, and that coastal humidity is rough on outdoor condenser coils. Corrosion builds faster here than in drier parts of the basin, which means capacitors, contactors, and coil leaks show up more often. Our technicians diagnose the specific failure, explain it in plain English, and hand you a written price before any work starts. When your AC dies on a 95-degree afternoon, the last thing you need is a voicemail tree. Full details live on our dedicated AC Repair in Walnut Park page.
Furnace Repair in Walnut Park
Winter in Walnut Park is mild by most standards, but those cool, damp nights still send people to the wall heater or floor furnace. The problem is that many of these units date back to the 1950s, and their igniters, thermocouples, and gas valves have decades of wear on them. We service and repair these older systems while also checking for the asbestos and clearance issues that come with the territory. If a repair fails within a year, the 365-Day Done Right Promise brings us back at no charge. See Furnace Repair in Walnut Park for specifics.
AC Installation in Walnut Park
Replacing an AC system in Walnut Park usually costs $3,500 to $7,500, and the real variable is how much of the existing ductwork and electrical can be reused. Flat roofs, shallow attic space, and older panels often mean a ductless mini-split or a low-profile packaged unit makes more sense than forcing a conventional split system into a house that was never built for it. We design around the house, not the other way around. Pricing and process details are on the AC Installation in Walnut Park page.

FAQs About HVAC Company in Walnut Park
Most Walnut Park calls get a same-day or next-day visit. Emergency calls, like a furnace that won’t light on a cold night or an AC that quits during a heat advisory, move to the front of the schedule. A live person answers the phone 24/7, so you’ll know your window before you hang up.
Yes, in many cases. Walnut Park’s older housing stock and the city’s seismic retrofit requirements can trigger additional permits when a rooftop unit needs new supports or when structural strapping is involved. We handle the paperwork and flag any asbestos concerns before work begins.
We can. Many Walnut Park homes still run on 1950s-era floor furnaces and wall heaters, and our technicians know how to service them safely. When the unit is beyond repair, we’ll quote a replacement that fits the existing space rather than insisting on a full ducted system the house can’t accommodate.

What Walnut Park Customers Say
"AC quit on the hottest day of the year of course. Coldharbour had a tech out that evening, found a bad capacitor, and had us cool again within the hour. Charged the quote, not a penny more."
- Doug Feeney"New mini split for the addition. Clean install, on time two days running, and the price matched the written quote to the dollar."
- Yvonne Prewitt"Thermostat and a weak blower. Fixed both in one visit, explained the guarantee, and didn't leave a mess. I've already recommended them to my neighbor."
