A new air conditioning system in Glendale typically runs $3,500 to $7,500, with most homes falling between $4,200 and $6,000 for a mid-range system sized to the square footage. Installation usually takes one to two days, and we can schedule most Glendale jobs within a week of the estimate. If you’re replacing a system that quit in the middle of a 95°F August afternoon, call (213) 531-5904 and a live person answers, day or night.
We know Glendale’s streets, its hills, and its houses. The flatlands south of Colorado Boulevard feel different from the canyons above Glenoaks, and the way we route refrigerant lines or set a condenser changes accordingly. You want a crew that has done this here, not one that is learning the postal codes on the drive in.
Why Cold Harbour Heating and Air Los Angeles Is Glendale’s Preferred AC Installation Company
Victor Mancini founded this company in 2003, and he built it on a simple habit: write down what you promise before you start the work. That habit shows up in every Glendale job we take. You get a written price before a single tool comes out of the truck. You get a firm arrival window. You get a written guarantee on the installation. And if anything about the work is not right inside 365 days, we come back and make it right at no charge. That is the 365-Day Done Right Promise, and the paper is handed to you before the technician leaves.
Glendale homeowners deal with a housing stock that most national HVAC chains do not train for. Pre-1960 stucco homes with clay tile roofs and tight attic spaces require a different approach than a 2005 tract house in the valley. Our technicians work on Carrier, Trane, Lennox, Goodman, and Rheem equipment, and they know how each system behaves when the outdoor condenser sits on a roof deck in direct afternoon sun. That matters when the streets are steep and the crane has to swing over a power line.
We also answer the phone. That sounds small until your AC dies on a Saturday night in July and the next four companies you call play a recording. With Cold Harbour, a live person picks up, every hour, every day. You tell us what is happening in your house, and we tell you when we can put a crew on it in Glendale.
Styles & brands we work with







Furnace Installation in Glendale
Furnace Installation in Glendale usually means swapping an aging floor furnace or a 40-year-old wall heater for a modern system that actually heats the far bedrooms. Glendale’s pre-war homes were built around floor furnaces, and those units are efficient at warming one hallway and not much else. We install furnaces throughout Glendale, and a typical job runs $3,500 to $7,500 depending on the size of the home and whether we are adding ductwork or tying into existing runs.
Floor Furnace Replacements in Older Homes
A 1930s Spanish Colonial off Kenneth Road often still has a floor furnace under a grate in the hallway. Removing it means capping the gas line, patching the floor framing, and running new supply and return air. We have done enough of these in Glendale that we can tell you on the estimate walk-through whether the existing chase can hold modern flex duct or whether a horizontal furnace in the attic makes more sense. The price is written down before we start, and it does not change at the door.
Dual-Fuel Setups for Glendale Winters
Glendale winter nights dip into the 40s, and while that is mild by national standards, it is cold enough that a heat pump alone struggles on the coldest mornings. We install dual-fuel systems that pair a heat pump with a gas furnace, so the heat pump handles the moderate days and the furnace takes over when the temperature drops. Given Glendale’s inland valley position and the swings between hot afternoons and cool nights, this configuration is one of the most common we recommend for whole-home comfort.
HVAC Installation in Glendale
HVAC Installation in Glendale covers the full system: the condensing unit outside, the evaporator coil inside, the line set connecting them, and the thermostat on the wall. In a Glendale home built before 1960, it often also means reworking the return air path, replacing old asbestos-wrapped duct boots, or adding a mini-split where no ductwork can physically fit. A complete system install in Glendale ranges from $3,500 to $7,500, and the exact price depends on system size, access, and whether any ductwork or electrical updates are needed.
Mini-Split Installation Where Ducts Can’t Go
Glendale’s older homes have attics too tight for standard trunk lines, and many owners do not want to drop ceilings to fit them. A ductless mini-split solves that problem. The indoor unit mounts on the wall, the outdoor condenser sits on a pad or roof bracket, and only a three-inch line set connects them. We install these regularly in the hills where running duct would mean tearing into original plaster and lathe. For a 1,500-square-foot Glendale home, two or three indoor heads usually cover the load.
Central Air Retrofit in 1920s – 1950s Homes
When a Glendale homeowner wants central air in a house that has never had it, the first question is where to put the air handler. We look at the attic, the closet space, and the crawlspace. In many Tudor Revival homes near the Rossmoyne district, a horizontal unit fits in the attic if the rafters are tall enough. In others, a compact vertical unit tucks into a hall closet. The job includes a manual J load calculation, because guessing at sizing in a stucco home with original single-pane windows leaves you with rooms that never cool below 80°F.
Trusted Brands We Service in Glendale
We install and service Trane, Lennox, Goodman, and Rheem equipment, and our techs are factory-trained on all of them. That means we do not push one brand onto every house. A Goodman heat pump might be the right call for a 1,200-square-foot bungalow off Pacific Avenue, while a Trane variable-speed unit makes more sense for a larger hillside home with multiple zones. Because we install these brands routinely in Glendale, we can pull most common parts from local supply houses the same day. You are not waiting a week for a condenser fan motor to ship from out of state.
Common AC Installation Problems We See in Glendale Homes
- Tight attics that can’t fit standard ductwork. Homes from the 1920s through the 1950s often have attics with 18 inches of clearance or less. That forces a switch to mini-splits or high-velocity systems, and we plan for that before drywall comes down.
- Condensers set too close to a neighbor’s window. Glendale code enforcement will stop work on a condenser that violates setback or sits too close to a property line. We pull the permit and check placement before the crane shows up.
- Rooftop units undersized for hill exposure. A load calculation that ignores afternoon sun on a west-facing roof in the Verdugo foothills produces a system that cannot hold 75°F on a 95°F day. We account for elevation and exposure.
- Clay tile roof damage during unit swaps. A rooftop condenser on a Spanish tile roof needs pans and proper foot traffic protection. Replacing a few cracked tiles after a careless install is a cost no Glendale homeowner should eat.

AfterPricing for AC Installation in Glendale, CA
| Service | Typical Price Range in Glendale |
|---|---|
| AC Installation | $3,500 – $7,500 |
| Furnace Installation | $3,500 – $7,500 |
| Tune-Up | $80 – $200 |
The biggest factors that move the number are the size of the house, whether the home already has ductwork, whether the condenser goes on the ground or the roof, and whether the electrical panel needs an upgrade to handle the new load. A rooftop unit in the hills that requires a crane will price higher than a ground-level swap on a flat lot off Central Avenue. Every estimate is free, and the price we show you is the price you pay. Call (213) 531-5904 and we will walk the property and hand you a written number.

FAQs About AC Installation in Glendale
Do I need a permit to replace an AC condenser on a roof in Glendale?
Yes, Glendale requires a permit for most condenser replacements, and rooftop work in historic districts adds a layer of review. We pull the permit, schedule the inspection, and make sure the installation passes the first time. Call (213) 531-5904 and we will tell you what your specific address requires.
Can I put a mini-split in my 1920s Tudor without cutting into the original plaster?
In most cases, yes. The line set runs outside the house, and the indoor wall unit mounts on a bracket that only needs a few anchor holes. We have installed ductless systems in Tudors throughout the Rossmoyne and Verdugo Woodlands areas without disturbing original plaster work.
Why did my new AC get quoted with a crane lift in Glendale?
If your condenser is going on a roof, especially on a steep lot, a crane is often the only safe way to set it. Hill streets are too narrow for a truck with a boom, and a rooftop pad on a clay tile roof cannot be reached with a standard two-man carry. We quoted a crane because it is the right way to do the job.
Are roof-mounted condensers on clay tile roofs a problem?
They work fine when installed correctly. The issue is that clay tile cracks easily under foot traffic, so the unit needs a proper curb or pad, and the line set needs to be routed without chipping tiles. Our crews use pans and walk boards, and we bring replacement tiles when a swap is required.
How do Glendale’s air quality days affect my new AC installation choice?
Glendale’s inland valley location traps smog and particulate matter, especially in August and September. That is a real reason to upgrade to a high-MERV filtration system during a new install. We recommend a 4-inch media cabinet on most Glendale jobs because the standard one-inch filter does almost nothing on a poor air quality day.
