Ray came out and fixed our mini split system. He was prompt and got the work done quickly. It was leaking so he fixed the leak and recharged our system. Good communication and a reasonable price. Will definitely be referring him to friends and family.

Frequently Asked Questions
How often should I service my HVAC system?
We recommend scheduling HVAC maintenance at least once a year—ideally in the spring for your AC and in the fall for your heating system. Regular service helps extend the life of your system and keeps it running efficiently.
What are the signs my air conditioner needs repair?
Common signs include weak airflow, unusual noises, warm air blowing, higher energy bills, and frequent cycling on and off. If you notice any of these, it’s best to schedule a professional inspection.
How long does a new HVAC system last?
Most HVAC systems last 12–15 years with proper care and maintenance. Upgrading at the right time ensures energy efficiency and avoids costly emergency repairs.
What’s the difference between central HVAC and ductless mini-splits?
A central HVAC system uses ductwork to distribute air throughout the home, while ductless mini-splits provide targeted heating and cooling for specific rooms. Mini-splits are ideal for homes without ducts or for room additions.
What’s included in your HVAC service and maintenance?
Our maintenance service includes inspecting components, cleaning coils, checking refrigerant levels, testing safety controls, and ensuring overall system efficiency. It’s a full checkup to keep your system in top shape.
How do I choose the right size HVAC system for my home?
The correct size depends on your home’s square footage, insulation, and layout. Our licensed technicians perform load calculations to recommend the perfect system for efficient comfort.
Why is regular HVAC maintenance important?
Maintenance helps prevent costly breakdowns, improves energy efficiency, extends system life, and ensures cleaner indoor air. Skipping service can shorten the lifespan of your unit.
Can a new HVAC system help lower my energy bills?
Yes, modern HVAC systems are much more energy-efficient than older units. Upgrading can significantly reduce your monthly utility costs while improving comfort.
How quickly can you respond to an emergency HVAC repair?
We understand that heating and cooling emergencies can’t wait. Our team provides fast, reliable service in Burnet County and surrounding areas to restore comfort as quickly as possible.
Do you offer warranties on new installations?
