Taking calls now·Speak with someone about your HVAC needs
Most of the calls we answer come down to two things: a house that won't cool, or a house that won't heat. Here's how we handle both.
A dead air conditioner on a hot afternoon is the call we run most. The usual culprit is a small electrical part, a capacitor or contactor, that our trucks carry, so most AC repairs are finished in one visit. Every repair comes with an upfront quote and an honest opinion on repair versus replacement.
A furnace that won't light on a cold night can't wait until morning. Most no-heat calls come down to a dirty flame sensor, a failed igniter, or a blower motor, and our trucks carry the common parts to fix them on the spot. You'll get a clear quote first, plus a safety check of the combustion and venting while we're there.
Not sure if you need professional help? These are the most common heating and cooling problems we solve in homes across the area.
When the AC runs but the house won't cool, the fault is almost always one specific component. We find it and fix it fast.
AC repairA furnace that lights and then shuts down within seconds usually has a dirty flame sensor or a failing igniter, quick fixes for an experienced tech.
Furnace repairEnergy bills creeping up while comfort drops means the system is working harder than it should, dirty coils, clogged filters, or failing motors are the usual suspects.
Maintenance & tune-upsR-22 refrigerant, rust on the cabinet, a compressor on its second capacitor, these are signs the smart money is on replacement.
System replacementA musty smell at startup often means moisture in the ducts or a dirty evaporator coil, worth addressing before it becomes a bigger air-quality problem.
Air duct cleaningAdditions and bonus rooms rarely get enough duct capacity. A dedicated ductless head fixes the problem permanently.
Mini-split installationAn HVAC system never fails at a convenient time. We schedule fast, show up on time, and arrive with the parts to finish the job.
Every technician has years of hands-on HVAC experience across air conditioners, furnaces, heat pumps, and ductless systems, and trains continually on new models and refrigerants. Your home gets a specialist, not a generalist with a parts catalog.
Plenty of companies sell a new system the moment yours hiccups. We diagnose first, explain what actually failed, and only recommend replacement when the math genuinely favors it.
We don't just swap the failed part. We check what killed it, airflow restriction, voltage, refrigerant charge, drainage, and correct that too, so the same failure doesn't repeat next season.
Year after year, Mandeville HVAC has been the team local families call when the AC quits or the furnace goes cold. We've serviced systems in nearly every neighborhood around town, and that track record shapes how we approach each job, from the first diagnostic to the final test.
Our team doesn't just swap parts and leave. We check the airflow, the charge, and the electrical supply driving the failure common to local homes and businesses. This local knowledge means faster diagnosis, fewer repeat visits, and systems that last.
Speak directly with a local HVAC expert. Upfront pricing, no obligation.
From the first call to the final airflow check, our method is built to solve the problem completely the first time.
Call (985) 274-8313 and we'll get you a price quote, often within a day. A few quick questions, cooling or heating, what the system is doing, how old it is, and we'll book a time that works for you.
We don't guess. The diagnostic covers the full system and turns into a straightforward recommendation with the cost spelled out up front.
We complete the approved work on the spot whenever possible: quality parts, code-compliant connections, and no shortcuts hidden behind the air handler.
Before we leave, the system is tested end to end and your questions are answered. Seasonal tune-up plans are available to protect the investment.

A house with no AC in a heat wave isn't something to wait out. Here's what our team does from your first call to restore your comfort fast.
Our team answers your call right away, gathers key details, cooling or heating, running or dead, any error codes on the thermostat, and books your visit, often same-day. We'll guide you on switching the system off if it's iced over or short-cycling in the meantime.
There's no waiting around for days. A fully equipped technician pulls up to your home, often same-day, with the parts already on board to diagnose and start fixing right then.
The technician confirms exactly what failed and why, then fixes it on the spot, and if the system is beyond saving, walks you through right-sized replacement options with real numbers and a realistic timeline.
We don't disappear once the visit is done. We follow up to confirm everything is holding, and for systems in their later years we'll suggest the maintenance rhythm that keeps them reliable instead of surprising you.
"Our AC died on the hottest day of the year and they had someone at our door within hours. He found a blown capacitor, swapped it from stock on the truck, and had cold air blowing in under an hour. Fair price, no drama, and he checked the rest of the system while he was there."
"Half our house was always five degrees warmer than the thermostat said. The tech rebalanced the dampers and fixed a kinked duct run, then set up a new smart thermostat and actually taught us how to use it. The whole house is finally even."
"Another company quoted us a full system replacement. Mandeville HVAC found a bad blower motor in twenty minutes and repaired it on the spot. The tech said the rest of the system had years left in it. That kind of honesty is rare."
We do more than patch the symptom. We make sure the job is done right. Every visit is backed by experienced technicians, quality parts, and a focus on fixing the cause.
The difference shows up in the results. Our technicians have logged real years on these systems, so they identify the actual fault the first time and fix it properly instead of throwing parts at your system until something sticks.
An oversized system short-cycles itself to death; an undersized one runs nonstop and never satisfies. Our team calculates the right capacity for your home and installs it to local code, permits included where required.
We don't wait for failures to profit from them. Every maintenance visit is thorough and documented. For hard-working systems, a $40 capacitor caught early can save a $2,000 compressor. Period.
