Kelteck Heating & Cooling | Reliable HVAC Repair in Harlingen, TX

Short cycling is a common issue in our Valley heat and often points to an overworked system or a refrigerant leak. At Kelteck, we start by checking for the local culprits—like a dirty air filter restricting airflow or an incorrectly sized unit for your home. We'll diagnose the specific cause, whether it's a faulty thermostat or a more complex compressor issue, and provide a clear repair plan. Addressing this quickly is key to preventing further damage and lowering your energy bills.

It depends on the age, condition, and efficiency of your current system. For repairs, we carry a large inventory of parts to fix most makes and models swiftly. However, if your system is over 10-15 years old, requires frequent repairs, or is causing unusually high energy bills—a common issue we've addressed since 1983—a replacement with a properly sized, modern unit may be more cost-effective. We provide honest assessments to help Harlingen homeowners make the right long-term decision for their comfort and budget.

Our installation service is thorough and tailored to your home. It begins with a detailed evaluation to ensure the new system is correctly sized for your Harlingen home's layout and insulation—critical for efficiency and preventing issues like coil freeze-ups. We handle the full installation, including ductwork assessment if needed, and ensure everything meets local codes. Our focus, as always, is on a precise installation that delivers reliable comfort and operates efficiently to help manage your energy costs from day one.
