Is Your Home or Business Struggling With Unreliable Heating or Cooling?

As a licensed HVAC contractor with decades of field experience, we understand the urgency and complexity of indoor comfort issues. At Grillos Heating & Cooling LLC, our team is dedicated to helping residential and commercial clients resolve heating and cooling problems quickly and efficiently. Based in Elmendorf, TX, we serve customers throughout a 45-mile radius with dependable service tailored to local climate demands. Many face inconsistent temperatures, rising energy bills, or aging systems that can no longer keep up. Our company stands apart by combining hands-on expertise, modern equipment, and transparent communication to guide you from diagnosis to resolution. With over 25 years in business and full certification and insurance coverage, we’ve earned the trust of homeowners and businesses alike who need real solutions—not guesswork—to restore their comfort fast.

We Specialize in the Following Services:

AC Installation

Aging air conditioning units often struggle to keep homes cool during peak summer months, leading to discomfort and high energy consumption. Our AC installation service addresses this head-on by assessing your property’s layout and selecting an energy-efficient system suited to your space. We use certified methods for proper sizing, placement, and testing to ensure smooth integration into your home or business. Customers benefit from improved airflow, consistent temperature control, and reduced monthly costs. Whether you're replacing an outdated unit or installing a system for new construction, our team delivers efficient results with minimal disruption.

AC Repair

It’s frustrating when your air conditioner stops working on the hottest day of the year or starts making strange noises without warning. That’s where our AC repair service comes in. We diagnose cooling problems quickly using specialized tools, including advanced detection technology to identify leaks or electrical faults. Our approach minimizes system downtime while ensuring lasting repairs that restore performance without unnecessary replacements. By addressing issues proactively, customers avoid larger breakdowns later and regain control over home comfort within hours rather than days.

Heating Installation

A cold indoor environment during winter can be more than uncomfortable—it can disrupt productivity or even pose safety risks. Our heating installation service helps prevent those outcomes through precision planning and expert implementation. We evaluate insulation levels, square footage, and usage patterns before recommending the right furnace, boiler, or heat pump setup. Once installed, customers enjoy steady warmth without fluctuating temperatures or excessive fuel use. Our installations are designed for long-term reliability with optional warranties available for peace of mind.

Heating Repair

If your heating system struggles to maintain temperature or fails altogether, it can make everyday living difficult—especially during freezing conditions. Our heating repair service responds swiftly to system malfunctions involving pilot lights, thermostats, burners, or ducting inefficiencies. Using proven diagnostic techniques along with stocked parts for common fixes, we complete most jobs on-site during our first visit. This reduces stress for customers and restores normal function so they can stay warm without delay or hassle.
