Furnace Maintenance

Furnace Maintenance is the scheduled work that keeps a heating system running safely between breakdowns, and it matters most in the weeks before you start relying on the furnace again. If your unit has gone a year or more without attention, or you’ve noticed a faint smell or a rougher start on cold mornings, that’s when a maintenance visit pays for itself. Paragon AC Repair inspects the burners, heat exchanger, blower and controls, then leaves you with a plain report of what we found and what it needs. A furnace tune up in Pasadena typically runs $80 – $200 depending on the system and how much cleaning is required, and the written estimate sets the final price.

What a Maintenance Visit Covers

We check ignition, flame quality, flue flow and the blower compartment, then clean what’s accessible and confirm the safety switches respond as they should. Anything borderline gets flagged and explained, not quietly replaced.

How Often to Schedule It

Once a year is the usual rhythm for a gas furnace that carries a home’s heating load. Homes with pets or heavy dust tend to benefit from a filter check more often than that.

Heat Pump Repair

Heat Pump Repair covers the one system in your home that handles both heating and cooling, which is exactly why a heat pump problem can leave you uncomfortable in either season. When the unit blows cool air in heating mode, defrosts oddly, or cycles without reaching the set temperature, the reversing valve, defrost board or refrigerant charge is usually where the fault sits. Paragon AC Repair diagnoses heat pumps the same way we approach furnaces, which means you don’t have to find a separate contractor mid-season. Typical heat pump repair in Pasadena falls within $150 – $700 depending on the part involved, and the written estimate sets the final price.

Heating Mode Faults

A heat pump in heating mode should push warm air at the vents within a few minutes of startup. When it doesn’t, we check the reversing valve and the auxiliary heat sequence first, since those account for most heating-side failures.

Defrost and Outdoor Unit Issues

The defrost cycle protects the outdoor coil, and a board that misfires will drag performance down in cool weather. We test the sensors and the cycle timing rather than guessing at the cause.

Heating Repair

Heating Repair is the broad category that covers gas furnaces, heat pumps and the controls that tie them together, and it’s what you need when a system runs but doesn’t actually warm the house. Short cycling, a blower that never shuts off, or a thermostat that reads one temperature while the rooms feel like another all point to a heating fault worth diagnosing properly. Paragon AC Repair handles both sides of home comfort, so the same company that services your cooling system can service your heating. Heating repair in Pasadena typically costs $150 – $700 depending on the fault and the parts required, and the written estimate sets the final price.

Airflow and Temperature Problems

Weak heat at the registers often traces back to a blower or duct restriction rather than the furnace itself. We measure airflow and static pressure to confirm before recommending work.

Controls and Thermostat Faults

A thermostat that calls for heat but gets no response can be a wiring, control board or sensor problem. We test each link in the chain instead of swapping parts until something works.

Boiler Repair

Boiler Repair addresses hydronic heating systems that warm a home through water rather than forced air, and those systems need a technician who understands pressure, circulation and controls. When radiators stay cold at the top, the boiler short cycles, or the pressure gauge drifts outside its normal band, those are the signals that a boiler needs attention. Paragon AC Repair inspects the circulating pump, expansion tank, aquastat and safety controls and explains what’s failing and what’s simply aging. Boiler repair in Pasadena generally runs $150 – $700 depending on the component, and the written estimate sets the final price.

Pressure and Circulation Checks

Low pressure and cold radiators often go together, and the cause is usually air, a failing pump or a weak expansion tank. We test circulation at the pump and confirm the pressure holds once the system is running.

Safety Controls on Hydronic Systems

Boilers rely on pressure relief and high-limit controls to shut down safely. We test each one and recommend replacement when a control no longer responds as designed.

Gas Furnace Repair

Gas Furnace Repair is work on the fuel side of the system, and it’s a job that belongs with a trained technician because gas, ignition and combustion carry real risk when something is wrong. A burner that won’t stay lit, a yellow flame instead of a steady blue one, or a smell of gas near the unit are all reasons to shut the furnace off and call rather than troubleshoot it yourself. Paragon AC Repair checks the gas valve, igniter, flame sensor and venting, then confirms combustion is behaving as it should before we leave. Gas furnace repair in Pasadena typically falls within $150 – $700 depending on the part, and the written estimate sets the final price.

Ignition and Flame Sensor Faults

A furnace that lights and then drops out within seconds is usually reading a false signal from the flame sensor. We clean or replace the sensor and verify the ignition sequence completes reliably.

Combustion Safety

We look at flame color, venting and the heat exchanger for signs of trouble, and we’ll say plainly if a furnace shouldn’t be run. That check is not optional in our book.

Furnace Tune Up

Furnace Tune Up is a focused service visit that cleans, tests and adjusts a working furnace so it runs efficiently through the season, and it’s worth booking before the first genuinely cold night rather than after. If your system heats unevenly, runs louder than it used to, or your energy bills crept up last winter, a tune up is a sensible place to start. Paragon AC Repair performs a furnace tune up in Pasadena for $80 – $200 depending on the system, and you get a written report of what we found rather than a vague handshake at the door. The written estimate sets the final price.

Flat Price, Written Report

The price is flat and set by the estimate, and our technicians aren’t paid on what they sell. If a part is fine, the report says so.

What Gets Measured

We test ignition timing, temperature rise and blower performance, then compare readings against the manufacturer’s spec. Numbers tell the story better than a visual look ever will.

Emergency Furnace Repair

Emergency Furnace Repair is the service you want when the heat fails and the house is getting cold fast, whether that’s overnight, on a Sunday, or right before a cold front moves through. No heat in cool weather is a health risk for older residents, young children and anyone with a respiratory condition, so it’s not a wait-and-see situation. Paragon AC Repair answers the phone 24/7 and dispatches technicians from 7am to 7pm, Sunday through Friday, and we’re closed Saturday. A call outside dispatch hours gets booked into the next opening. Emergency furnace repair in Pasadena fits within $150 – $700 depending on the fault, and the written estimate sets the final price. There’s no overtime charge.

Same-Day Service

When you call early, we often get to the same-day repair window. You’ll get a clear arrival picture when we book the visit.

What to Do While You Wait

Shut the furnace off at the thermostat if you smell gas, and open a window near the unit. If you have a carbon monoxide alarm and it sounds, leave the house and call from outside.

Brands We Service

We’re certified to work on nine of the industry’s leading HVAC brands, which means our technicians can diagnose the system in front of them rather than the one brand they happen to sell. Carrier equipment is common across Pasadena homes, and we know where those furnaces tend to wear first: the igniter and the inducer assembly. Trane units hold up well but their control boards are specific, and we test them properly instead of replacing on suspicion.

Lennox and Goodman systems both show up often in this area, and each has its own quirks around flame sensing and blower settings that a generalist can miss. Our brand-agnostic approach means recommendations are driven by your system and your budget, not a manufacturer relationship. Whether you have Carrier, Trane, Lennox, Goodman or any other make, we can help.

Signs You Need a Pro Right Now

• You smell gas. A gas odor near the furnace means shut it off, leave the area and call from a safe spot. Gas faults are not a DIY job.
• The flame is yellow, not blue. A steady blue flame is normal; a yellow or flickering one can signal incomplete combustion. That’s a safety issue worth a prompt visit.
• The furnace cycles on and off repeatedly. Short cycling stresses the heat exchanger and the blower over time. It usually traces to a limit switch, airflow or a thermostat fault.
• The blower runs but the air is cold. Air moving without heat points to an ignition or gas valve problem, and running it that way wastes electricity without warming anything.
• Your carbon monoxide alarm sounds. Leave the house immediately and call for help from outside. Do not reset the alarm and go back to normal.

Our Process, Step by Step

1. 1
   We take the call and book the visit. You describe what the system is doing, and we set an arrival window that fits your day. No vague “sometime today” promises.
2. 2
   We diagnose before we quote. Our technician tests the system with combustion analysis and electrical meters, then explains what’s actually failing. You see the evidence, not a sales pitch.
3. 3
   You get a written estimate. The price is set per job, in writing, before any work begins. If the fix is simple, the estimate says so.
4. 4
   We do the repair and verify it. After the repair, we run the system through a full cycle and confirm temperature rise and combustion readings are where they should be.
5. 5
   We tell you what’s next. If the furnace has life left, you’ll hear that. If a furnace repair won’t hold and replacement makes more sense, we’ll say so plainly and walk you through the options.
