HVAC Services Saint Martinville LA | Call M & H Air Conditioning & Heating

It's a great first step to check the batteries, but inconsistent heating or cooling in our humid climate often points to a deeper issue. A malfunctioning thermostat can cause your system to short-cycle or not turn on at all, leading to discomfort and higher energy bills. Our technicians can quickly diagnose if it's a simple wiring problem, a faulty sensor, or a sign your HVAC system needs attention, providing a clear, honest assessment to get your home comfortable again.

Our high humidity makes ducts a prime spot for mold. Key signs include a musty odor when the system runs, visible mold around vents, or increased allergy symptoms at home. M & H helps by first inspecting your ductwork with specialized tools. If mold is present, we perform professional duct cleaning and EPA-approved antimicrobial treatments to safely remove the growth and spores, protecting your system and your family's indoor air quality.

Beyond specific thermostat or mold issues, we frequently see systems struggling due to lack of maintenance in our demanding climate. Dirty coils, clogged filters, and refrigerant issues cause inefficiency and breakdowns. Our most effective solution is a preventative maintenance plan. This includes seasonal tune-ups to clean critical components, check refrigerant levels, and ensure everything runs efficiently, which prevents minor issues from turning into major, costly repairs during our hottest and coldest months.
