Air Conditioning Services in Mercedes, TX

Without a functioning air conditioner, your home or business turns into a hot box where relaxing is next to impossible. We provide prompt AC services to restore your home to a comfortable temperature quickly. 

AC Repair

You may need an AC repair if your unit has begun making strange noises, you notice odd smells, the thermostat temperature lingers a few degrees higher than you programmed it, or the unit stops turning on entirely. Our HVAC company arrives at AC repair jobs with all the equipment we may need to resolve the issue. 

AC Installation

It may be time for a new AC installation if your AC must run constantly to cool your home, your system is more than 20 years old, or your energy bills are unreasonably high. Allow our licensed and insured contractors to install a new unit that suits your budget and energy goals. We’ll haul away the old unit and ensure the new one performs optimally before leaving. 

AC Maintenance

Annual AC maintenance keeps your air conditioner in the best shape to continue cooling your home or business long-term. We complete a thorough checklist of services as part of our AC maintenance program. Rest assured that your AC will perform reliably for the year after we have given it a once-over. 

Heating Services in Mercedes, TX

Even if you only use your furnace or heat pump for a few weeks out of the year, you deserve peace of mind that it will work as it should when you need it. We provide comprehensive heating services in Mercedes, including:

Heating Repair

A malfunctioning furnace or heat pump can quickly turn your home into an uncomfortable environment. If your heating system heats your home unevenly or fails to warm your property to the desired temperature, give our team a call. We will diagnose the problem and repair it in the same visit. 

Heating Installation

Having the right heating system in your home, business, or new build lets you minimize your energy usage while maximizing your comfort. Allow our expert contractors to recommend a furnace or heat pump that suits your property’s dimensions, meets your budget, and includes the amenities you desire — like a smart thermostat or energy-efficiency features. 

Heating Maintenance

Keep your heating system in the best condition even during the off months with comprehensive heating maintenance. We will inspect, clean, and repair your system, preparing it for another year of reliable performance.
