What are the signs?
You Should replace your HVAC System?
Frequent Repairs
If you’re calling for service multiple times a year, those repair costs add up quickly. At this stage, a new system is the more practical financial choice.
System Age (10–15+ Years)
Most systems in Texas are working hard year-round. Once you’re past the 10–15 year range, efficiency drops and breakdown risk increases.
Uneven Temperatures
Hot and cold spots throughout the home can indicate your system is no longer able to properly distribute air or keep up with demand.
Major Component Failure
Issues like a failed compressor or evaporator coil can be costly enough that replacing the system makes more financial sense.
Rising Energy Bills
An increase in utility bills without a change in usage often means your system is losing efficiency and working harder than it should.
Poor Humidity Control
In Texas, humidity matters. If your home feels sticky even when cooling, your system may not be operating effectively anymore.
What to Expect
From installation to emergency repairs, we ensure your comfort year-round with prompt, professional service.
We Evaluate
Your System
We look at your current equipment, home layout, and how the system has been performing. This is about understanding the full picture not just the unit.
We Ask the
Right Questions
We go over comfort concerns, hot or cold spots, energy bills, and how you use your home so we can recommend the right setup.
We Show You
Clear Options
You will get straight forward options with different price points and efficiency levels. Everything is explained so you can compare and decide what makes sense.
You Decide the
Next Step
No pressure. If a repair makes more sense we will tell you. If replacement is the better long term option, we will show you why and you can move forward when you are ready.
Choosing the Right System
We typically walk homeowners through a few key considerations:
Efficiency (SEER2 Ratings)
Higher efficiency can lower long-term operating costs
System Size & Fit
Proper sizing is critical for comfort and longevity
Single Stage vs. Variable Speed
Comfort, noise levels, and performance differences
Why Installation Quality Matters
A high-end system installed incorrectly will still perform poorly. A properly installed system—even at a mid-range level—will often outperform a poorly installed premium system. We focus on:
Correct system sizing
Proper airflow and duct connections
Clean, code-compliant installation
System testing before completion

Outstanding customer service and technician. Not only was thorough. He was respectful and explained everything in a detailed manner. In addition, my wife and I work from home and have a sign on the door to not to knock or ring the door bell. He respected that and called me. That is very much appreciated. Ever since I switched to Weiss, I only have great things to say. The other A/Heating companies don't compare. Switch now if you want outstanding service, repairs, customer service, and support.-Tony M
Installed 2 new Trane TrueComfort 20 systems. A 4 ton and a 3 ton true variable speed system (new condensor, coil and furnace for each). They did a great job installing the new units. If I had any concerns or questions throughout the process, they addressed them immediately. Overall very happy with what I received, and very happy with Weiss AC. I highly recommend them. -David Faulk
I really love these guys. They are experts with a clear vision to service their customers. They inspected my unit, and discovered a builder warranty problem. I appreciate their honesty and their dedication. I can’t recommend them enough!! - Catherine Jackson
FAQs
Your HVAC Questions Answered: Quick, Clear Solutions.
Do you offer financing?
Yes. We offer financing options for qualified homeowners with simple monthly payment plans. Once approved, we can move forward with scheduling so you don’t have to delay getting your system replaced.
How do I know if I actually need replacement vs repair?
It comes down to a few factors: system age, repair cost, frequency of breakdowns, and overall performance. If a repair makes sense, we’ll recommend it. If the system is near the end of its life or the repair is significant, we’ll show you replacement options so you can compare.
Will I need new ductwork?
Not always. Many homes can reuse existing ductwork if it’s in good condition and properly sized. If we see issues like air leaks, poor airflow, or undersized ducts, we’ll walk you through what needs to be addressed and why.
Can I replace just one part of the system?
In some cases, yes—but it’s not always recommended. Systems are designed to work as matched equipment. Mixing old and new components can lead to efficiency loss, performance issues, or reduced lifespan. We’ll explain both options so you can make an informed decision.
What warranty comes with a new system?
Most new systems include a manufacturer warranty on parts when the equipment is registered. We also review any extended coverage options available so you understand what is and isn’t covered.
How long does it take to install a new HVAC system?
Installation typically takes 1 to 2 days, depending on system complexity and setup.
