Smart HVAC design makes a comfortable home

Right-sized HVAC system. Right-sized ductwork. Right airflow. Right efficiency. Right everything. 3H’s whole-home approach results in the perfect HVAC design for your home.

We'll not only design the right HVAC system for your home, we’ll install it, too. One stop - hassle free - all of your HVAC needs. Boom!

At 3H, we work closely with homeowners to understand their heating, air conditioning, and energy efficiency challenges. Then we design and
install HVAC systems that offer:

  • Consistent comfort throughout your home: We optimize HVAC for reliable comfort in every room – no more hot or cold spots.
  • Energy efficiency that fits your budget: When it comes to HVAC equipment, we offer options for all budgets. From standard to high efficiency, we’ll help you select the right system.
  • Properly sized and sealed ductwork: Clean, sealed ducts are key to HVAC performance. We make sure your ducts are the right size for your home.
  • Smart HVAC controls: Smart thermostats and digital programmable thermostats make it easy to save energy while maintaining a comfortable living space. WiFi compatible.

Wondering about our (brilliant) ground up system designs for HVAC? At 3H, we rely on ACCA industry standards for all of our designs. Specifically, we follow:

  • Manual J (Load Calculation): This exercise helps us determine the right HVAC equipment size for your home. New construction and remodels are our specialty.
  • Manual S (Equipment Selection): After performing a load calculation, we use this standard to identify equipment that provides optimal comfort.
  • Manual D (Ductwork Calculations): Duct sizing has a tremendous impact on comfort. This standard ensures that we size your ductwork properly.
  • Manual T (Register sizing): Register size matters! We perform this calculation to make sure we design your system with the right-size registers (also known as “grilles” or “diffusers”) in the right places.

We have been working with 3H for about 6 years now. Their technicians are always prompt, honest, and helpful. Their pricing is very competitive. I would recommend them to anyone.

My air conditioner went out over a week ago. When I noticed my a/c wasn't working, and it was tripping the inside breaker. I reached out to 3H contracting the owner Brian sent Tristan out the very next day. Definitely will use them in the future for all my a/c & heating needs.
