Overview
Heating and cooling help in Duarte
Duarte is where Marco's Heating & Air keeps its head office, on Bettyhill Ave. Technicians start and end their day here, and the parts room is here too. For Duarte homeowners, that means a short drive to your door when the air conditioning quits on a 100 degree afternoon or the heat goes out on a cold winter night. The city is compact, stretching from the foothills down across Huntington Drive and the 210 Freeway, with City of Hope near the junction of the 210 and 605.
Being close also helps with follow-up. If a part has to be ordered, we can return quickly once it arrives, and if a repair needs a second look, it is easy to stop by. We serve single-family homes, condos and small commercial buildings across Duarte, and we treat every emergency call the same way: a clear diagnosis, a price before work starts, and a repair done properly.
Duarte homes and the systems that serve them
Much of Duarte's housing went up in the 1950s and 1960s as single-story ranch homes on tract streets. These homes usually have a furnace in a hall closet, the garage or the attic, ducts running through the attic, and an air conditioner or heat pump outside along a side yard. Many systems have already been replaced once, so equipment ages vary widely from house to house on the same block, and two neighbors can have very different problems.
Homes up toward the foothills are often newer and larger, and some sit on slopes with more wind exposure. Duarte is inland and gets long summer heat, so cooling systems run hard from June into October, and that is when most of our emergency calls come in.
Common problems
Emergency calls we answer most in Duarte
No cooling in a heat wave
Failed capacitors, burned contactors and fan motors that seize after years of heat are common. Most of these parts ride on our trucks, so the repair is often finished during the same visit.
Refrigerant leaks and frozen coils
A system low on refrigerant cools poorly, then the indoor coil freezes. We find the leak with electronic detection or dye, repair it where that makes sense and recharge to the correct level.
Compressor failure on older units
A compressor that has run hot for years can fail outright. We test the windings and the starting parts, then explain whether replacing the compressor or the whole unit is the better value.
No heat on a cold morning
Furnaces that sat all summer can fail on the first cold morning. Igniters, flame sensors and pressure switches are the usual suspects, and we test each one before replacing anything.
Heat pumps stuck in one mode
A failed reversing valve or defrost control can leave a heat pump blowing cool air in winter. We trace the fault to the right part rather than swapping parts until something works.

Why emergency and repair work leads in Duarte
Being based in Duarte, we built this page around the calls our neighbors make most. Emergency HVAC repair covers nights, weekends and holidays. AC repair and furnace repair handle the everyday failures. Heat pump repair matters as more Duarte homes switch from gas. Refrigerant leak repair and compressor replacement are the bigger fixes, and for those we always compare the repair cost with the age of the system and the price of replacement, so you can decide with both numbers in front of you.
AC Repair
Warm air, a humming outdoor unit or a tripped breaker: we find the failed part and fix most AC problems in one visit.
Learn moreFurnace Repair
No heat on a cold night? We trace the ignition sequence, find the failed part and fix most furnaces in a single visit.
Learn moreHeat Pump Repair
Diagnosis and repair for heat pumps that will not heat, will not cool, ice up, trip breakers or show inverter fault codes.
Learn moreAC Compressor Replacement
We test windings, start components and pressures to confirm a dead compressor, then replace it and protect the new one from the same fate.
Learn moreRefrigerant Leak Repair
We trace refrigerant leaks with electronic detectors, bubble tests and nitrogen pressure, then repair and recharge by weight.
Learn moreDuarte notes: utilities, permits and heat
Duarte homes get electricity from Southern California Edison and gas from SoCalGas. If a repair turns into a replacement, ask about current SCE or SoCalGas rebates and state heat pump incentives when funding is open. We handle the permit where the city requires one, and California energy rules (Title 24) can require duct leakage testing when an AC or furnace is replaced. Ordinary repairs usually need no permit.
Summer heat in Duarte often climbs into the high 90s and past 100 F. During a heat wave, set the thermostat a few degrees higher, close blinds on the west side and keep the filter clean to take strain off the system. If the unit stops, turn it off at the thermostat and call rather than restarting it again and again.
Questions
Duarte heating and cooling questions
Our head office is on Bettyhill Ave in Duarte, so most Duarte addresses are a short drive away. We answer the phone 24/7 and send the nearest available technician. Arrival time depends on how many calls are open at that hour, and we give you an honest estimate when you call so you can plan your evening or morning.
It depends on where the leak is and how old the system is. A leak at an accessible valve or fitting is usually worth repairing. A leak inside an old indoor coil, especially on a system using an older refrigerant, often makes replacement the better value. We show you where the leak is and give both prices before you decide.
Turn the system off at the thermostat, check that the breaker has not tripped, and look at the filter. If the outdoor unit is humming without running, or the indoor coil is iced over, leave it off and call. Running a failing unit can damage the compressor. Close west-facing blinds and use fans while you wait for the technician.
We do both, depending on the situation. If the system is fairly young and the rest of it is sound, replacing the compressor can make sense, especially if a manufacturer warranty still covers the part. If the system is older and other parts are worn, a new system is usually the better value. We explain the numbers and let you choose.
