Frequently Asked Questions About HVAC Service in LaPlace
Our shop is located in Gramercy, which puts us a short drive from LaPlace. For emergency calls, we do everything we can to get a technician out the same day. For scheduled appointments, we’ll work around your availability and get you on the calendar as quickly as possible.
It’s one of the most common culprits. A system that’s low on refrigerant, running with a dirty coil, or working through leaky ductwork has to run longer and harder to maintain the same temperature — and that shows up directly on your energy bill. Age plays a role, too; older systems are significantly less efficient than newer ones. If your bills have climbed without an obvious explanation, a diagnostic visit from Big Chief’s will usually find the answer pretty quickly.
Both. Big Chief’s handles the full range: repairs, maintenance, and complete system installations and replacements. As an Independent Trane Dealer, we install Trane equipment on new and replacement jobs, and we offer free estimates so you know exactly what you’re looking at before any work begins. If you’re on the fence about whether to repair or replace, we’ll give you an honest breakdown of both options.
Absolutely. The humidity along the River Parishes puts consistent pressure on HVAC equipment — it makes systems work harder to dehumidify the air, increases the risk of mold and biological growth inside the system, and can accelerate wear on certain components over time. Regular maintenance helps catch moisture-related issues early, and indoor air quality solutions like UV lights and air purifiers can address the effects humidity has on your home’s air.
Big Chief’s offers financing through Wells Fargo for qualifying customers. Whether you’re replacing a system that gave out unexpectedly or planning ahead for an upgrade, financing helps you move forward without having to put the whole cost out of pocket at once. Special financing options may be available — give us a call, and we’ll walk you through what you qualify for.
