What does the One Hour mean in your company name?

The 'One Hour' in our company name indicates our guarantee to be at your home in the predetermined window quoted when you set your appointment. If we do not show up within that window, your service call fee is waived. 1. Express Appointment: This is an appointment that is scheduled during a specified one-hour time slot. You are promised that a technician will arrive at your home within this one-hour time window. You will also receive a call when the technician is en route to your home. 2. Reserved Appointment: This is an appointment that is scheduled during a specified, two-hour time slot. You are promised that a technician will arrive at your home within this two-hour time window. You will also receive a call when the technician is en route to your home. 3. Standard Appointment: This is an appointment that is scheduled during a specified four-hour time slot. You are promised that a technician will arrive at your home within this four-hour time window. You will also receive a call when the technician is en route to your home. 4. Stand-By Appointment: This appointment is for overflow situations. This appointment will not have a specified time. You will receive a call when the technician is en route to your home. 5. Emergency Appointment: This appointment is for an unspecified time after normal business hours Monday – Saturday and all day on Sundays/Holidays. Calls are dispatched in the same order they are received. You will also receive a call when the technician is en route to your home.

Do you service emergencies after-hours?

Yes, we offer emergency services 24-hours a day, year-round.

How much will my service cost?

The size and complexity of your HVAC issue will determine the cost. Because our trained, licensed HVAC technicians must diagnose the issue before we are able to quote you an accurate cost, we require an appointment to be set to complete a diagnostic on your system. Once the diagnostic is complete, your One Hour(R) technician will walk you through all costs using our Straightforward Pricing(R) Guide so there are never any surprise fees.

How often should I service my HVAC system?

It's ideal to service your cooling system each spring and your heating system each fall to ensure you find small issues before they become big problems.

How often do I need to change my HVAC filter?

Your filter should be changed every one to three months, depending on conditions in your home and your region's climate.

Do you offer purchase financing?

We work built relationships with several lenders to ensure our customers are able to restore comfort in their homes. Ask your technician about your financing options.

What are the advantages of a smart thermostat?

Smart thermostats learn a household's patterns and adjust heating and cooling according to when a home is occupied, give homeowners the ability to control the thermostat remotely, and enable homeowners to reduce their energy use, saving you money.

HVAC means Heating, Ventilation, and Air Conditioning. HVAC systems refer to air conditioners, furnaces, and any unit that cools indoor spaces during the summer and warm them in the winter. In general, an HVAC system takes in air, heats or cools that air, and blows it into a room or any indoor space. While many homes have separate air conditioning and heating units, others have a heat pump that cools and heats the house. Not only do HVAC systems maintain desired temperatures, but they also improve indoor air quality and regulate humidity levels. But most importantly, these units provide comfort all year round.

What is a SEER2 Rating?

The SEER2 (seasonal energy efficiency ratio) is a measure of the efficiency of your heating and cooling system.The higher the SEER2 rating, the more efficiently a unit operates. The SEER2 rating of any given unit can range anywhere from 13 to 21.

“Jason did a great job servicing my AC unit. When and preformed lots of test and said we are all good. Did recommend getting a turn off switch in the attic so the overflow water doesn’t flood up in that area. Considering doing this. Thanks Jason for your expertise”

Bryan Johnston

General Manager

My name is Bryan Johnston, and I take great pride in being a fourth-generation general contractor with a profound passion for the heating, air conditioning, and plumbing industries. Over the past 33 years, I have dedicated myself to this field, during which I had the honor of designing and establishing the first rainwater collection system in the state of Texas, along with setting new water purification standards. My extensive work in these areas prompted the Texas State Plumbing Board to create two new endorsements specifically for this type of work.

My journey began as a young boy, accompanying my grandfather and father to job sites, where I absorbed the intricacies of the trades. As I grew older, I diligently pursued the knowledge required for licensing and certifications, ultimately establishing myself as a professional in the industry. After two decades of hands-on experience, I ventured into entrepreneurship by owning and operating two successful plumbing companies and a plumbing supply house for over a decade. These experiences not only sharpened my technical skills but also taught me the importance of customer service and the value of building lasting relationships with clients.

After selling my businesses, I initially embraced early retirement, believing it was time to step back and enjoy life. However, I soon realized that retirement was not what I truly desired. I missed the thrill of tackling complex technical challenges and the fulfillment that comes from helping people solve their problems. It became clear to me that my true calling lay in returning to the industry where I felt my skills could make the greatest impact.

Reentering the heating and air conditioning field has reignited my passion for this work. I take great pride in my ability to lead and mentor others, sharing my knowledge and experience with those who are just starting their careers.
Outside of work, I enjoy engaging in water sports and strive to maintain peak physical condition. Whether I’m on the water or in the field, I approach every challenge with enthusiasm and dedication.

This is my story—a journey fueled by passion, perseverance, and an unwavering commitment to excellence in the heating and air conditioning industry.

Associate Technician

I'm Jesus Jaramillo, an HVAC technician and installer passionate about helping others through hands-on work. Though I'm early in my career, I'm dedicated to learning and growing in this field. I excelled at Universal Technical Institute, quickly mastering heating, ventilation, and air conditioning systems, and I enjoy solving real-world problems to improve home comfort and efficiency.

I have a natural ability for hands-on work, which extends beyond HVAC to building custom car parts with my father. This passion keeps me challenged and constantly thinking about how things work. What drives me most is serving others through technical excellence, ensuring families have reliable and safe systems.

I'm committed to showing up every day with purpose and integrity, delivering quality work, and earning the trust of my clients. My journey is just beginning, fueled by curiosity, hard work, and a deep commitment to the HVAC trade.
