AC Installation in Pasadena - Load-Calculated, Priced in Writing

Trusted AC Installation for Pasadena Homeowners

If your system is 12 to 15 years old, running constantly to hold 76 degrees in July, or you’ve already paid for two repairs this year, a new installation usually costs less over five years than keeping the old unit alive. Pasadena’s humid Gulf summers push equipment hard, and a mismatched or undersized system never recovers that lost ground. Our technicians have up to 9 years of experience, we’re licensed and insured, and we install to the Paragon standard, which means correctly sized, correctly charged, and tested before we leave. We work on nine leading brands, so the recommendation you get is about your house, not a manufacturer we’re pushing. Paragon AC Repair offers free estimates, and we can arrange same-day service on many calls. Call (866) 982-5097 to get started. We answer 24/7, with fast dispatch from 7am to 7pm.

Furnace Installation

Furnace Installation is the replacement of the heating side of your system, and for Pasadena homeowners it’s usually a shorter, milder heating season that makes right-sizing more important than raw output. You need it when the heat exchanger has cracked, when the unit is old enough that parts get scarce, or when repair after repair has stopped making financial sense. Paragon AC Repair handles furnace installation alongside our cooling work, so you’re not calling one contractor in July and a different one in January. Typical furnace installation runs $3500-$7500 depending on size, efficiency tier, and whether venting or ducting needs changes, and the written estimate sets the final price.

Heating Side of the Same System

Most homes in Pasadena heat with a gas furnace paired to a central air handler, so installing the furnace means confirming the blower and coil match the AC you already have. We check that match before we order rather than after.

Sizing and Combustion Checks

A furnace that’s oversized short-cycles, and one that’s undersized runs cold in the few weeks each winter actually bites. We size from the home’s load and verify combustion and venting on gas units before the job is closed out.

HVAC Installation

HVAC Installation means installing the heating and cooling system together as one matched set rather than piecing in a replacement indoor unit against an aging outdoor one. You need it when both halves are the same age and nearing the end, when a previous installer mismatched the coil and condenser, or when you’re converting to a system with an air handler that serves both seasons. Paragon AC Repair covers the full scope, so cooling and heating are one project, one company, one point of accountability. A whole-system installation typically runs $3500-$7500, with the exact figure settled by the written estimate after we see the ductwork, the electrical service, and the equipment you choose.

Matched Equipment Matters

When the indoor coil doesn’t match the condenser, capacity drops and the compressor works harder than it should. We match components because the rated efficiency number only holds when the set is designed to work together.

Ductwork Review Before Ordering

Leaky or undersized ducts quietly undo a good install, so we look at static pressure and duct condition first. Right-sizing duct work to the new equipment is part of the estimate, not a surprise line item later.

Heat Pump Installation

Heat Pump Installation is the fitting of a single system that heats and cools by moving refrigerant rather than burning fuel, and it suits Pasadena’s climate well because winters are mild and cooling is the long season. You need it when your gas furnace and AC are both near replacement, when you want to drop gas from the home, or when your existing heat pump has failed and the compressor isn’t worth saving. Paragon AC Repair installs heat pumps from Carrier, Trane, Lennox and other major makes, sized to your home and balanced for humidity control as well as temperature. Expect a typical $3500-$7500 for a standard installation, with the written estimate fixing the final price.

Heating Season Demand

Pasadena winters are short and rarely hard, which means a heat pump’s cold-weather performance is less of a limiting factor here than in northern markets. What matters more is how the system manages humidity through the long cooling season.

Refrigerant Line and Drain Care

New heat pumps need correctly sized line sets and a condensate path that won’t back up in a humid climate. We verify both before the system is commissioned.

Ductless Mini Split Installation

Ductless Mini Split Installation is the addition of one or more wall-mounted indoor heads connected to an outdoor unit, delivering conditioned air directly into a room without ducts. It’s the right call when you’re adding living space, finishing a garage conversion, cooling an upstairs room that never gets comfortable, or dealing with a house where the duct system can’t be fixed economically. Paragon AC Repair handles multi-zone designs from Goodman and other brands, sized per room, with line routing planned to keep the exterior clean. A single-zone install typically falls within our standard $3500-$7500 range, and multi-zone work is priced from the written estimate after we’ve walked the rooms.

Zoning for Additions

Every head is its own zone, so a converted garage or a rear bedroom gets set its own way. That flexibility is the main reason homeowners in Pasadena choose ductless for additions instead of extending existing duct runs.

Mounting and Line Routing

Head height, drainage slope, and where the line set exits the wall all get worked out before installation day. Planning that up front keeps the finished job tidy on the outside of the house.

AC Replacement

AC Replacement is the removal of a failed or worn-out cooling system and installation of a new condenser and coil, and you need it when the compressor has failed on an out-of-warranty unit, when R-22 refrigerant makes repairs impractical, or when repair quotes are climbing past the halfway mark of replacement cost. Paragon AC Repair recommends replacement only when the numbers actually say so, and we’ll tell you plainly when a repair still makes sense. Typical replacement in Pasadena runs $3500-$7500 depending on tonnage, efficiency tier, and whether the line set or electrical disconnect needs updating, with the written estimate setting the final number.

When Repair Stops Making Sense

A single failed capacitor is a repair. A failed compressor on an aging system is usually a replacement conversation. We walk you through the cost comparison instead of steering the answer.

Disposal and Permits

Removing the old equipment and recovering refrigerant properly is part of the job. Most cities require a permit for this work, so ask your city’s building department and we’ll coordinate what’s needed.

Central Air Conditioning Installation

Central Air Conditioning Installation is the fitting of a full ducted system: outdoor condenser, indoor coil and air handler, refrigerant lines, thermostat, and controls. You need it when you’re moving into a home that has a furnace but no cooling, when the existing ducted system has failed, or when you’re replacing both halves at once for a matched, efficient set. Paragon AC Repair installs central systems from Bryant, American Standard and the other major brands we’re certified on, sized from a load calculation rather than a square-footage guess. A standard central installation in Pasadena typically runs $3500-$7500, and the written estimate you receive sets the final price.

Load Calculation First

Guessing tonnage from square footage is how systems end up short-cycling and struggling in July humidity. We run room-by-room load calculations so the equipment matches the house.

Thermostat and Airflow Setup

After installation we commission airflow and set the thermostat to the system’s actual stage and capacity. A properly configured system delivers what the spec sheet promised.

Brands We Service

We’re certified to work on nine of the industry’s leading HVAC brands, and that range is the reason we can diagnose the system in front of us instead of the one brand we happen to sell. We service Carrier equipment and know where it wears, from the condenser fan motor to the control board. We service Trane systems and understand how their components fail in a humid cooling season. We handle Lennox units and can match their indoor coils to a new condenser instead of forcing a full changeout. We also work on Goodman, Rheem, York, Daikin, Bryant, and American Standard.

What that means for you is a straight recommendation: if your Trane condenser has life left and only the coil is bad, we’ll say so. If your Goodman air handler is the weak link, we’ll price the repair against a replacement and let you decide. Our model is brand-agnostic because your budget and your house should drive the answer. Whether you have Carrier or any other make, we can help.

Signs You Need a Pro Right Now

• Rising electric bills with a working system. A unit that’s drawing more power month over month is often failing to hold the temperature or running on a failing compressor. That’s a signal worth diagnosing before summer peaks.
• The house won’t get below 78 in the afternoon. A system that runs continuously without reaching the set point is either undersized, low on refrigerant, or losing air through duct leaks. None of those fix themselves.
• Ice on the outdoor unit or the refrigerant line. That’s usually a refrigerant charge or airflow problem, not a sign the unit is working overtime. Running it in that state can damage the compressor.
• Rattling, grinding, or a compressor that clicks and stops. Mechanical noise points to failing bearings or a compressor on the way out. Electrical panels and capacitors can store a lethal charge, so this is not work for a homeowner.
• Water pooling around the indoor unit. A clogged drain line in Pasadena’s humidity can overflow and damage ceilings, and it often signals a coil or pan issue underneath. Get it looked at before the drywall tells the story.

Our Process, Step by Step

1. 1
   Conversation and site visit. We ask what’s actually bothering you about the house, then walk the equipment, the ducts, and the electrical service. That visit is what the free estimate is built on.
2. 2
   Load calculation and system sizing. We size the equipment to the home using room-by-room load figures, not a rule of thumb. Getting this right is the difference between a system that lasts and one that struggles.
3. 3
   Written options, no pressure. You get equipment options and a written price for each, with the trade-offs spelled out. We don’t sell a manufacturer relationship; we sell the right fit.
4. 4
   Installation day. Lines, drains, electrical, and airflow get set and verified against spec. Refrigerant charge is measured, not guessed, and duct connections are sealed and tested.
5. 5
   Commissioning and walkthrough. We run the system, verify temperatures and airflow, and show you the thermostat and filter routine before we leave. Any paperwork to coordinate with your insurer is handled at this stage.
