Whether you’re upgrading an aging system or building a new home, our team ensures your HVAC system is engineered, installed, and optimized for comfort, efficiency, and long-term performance. We don’t just sell systems—we design and install HVAC solutions tailored to your home’s unique needs.

Experts in HVAC Engineering

Every HVAC installation we complete begins with a thorough engineering process to ensure optimal comfort, energy efficiency, and system longevity. HVAC engineering helps us determine the exact equipment size, duct layout, and airflow design that’s best suited for your home—not just the most expensive system. This process eliminates guesswork and reduces the risk of future breakdowns or energy waste.

Our certified heating and cooling experts can provide a wide array of engineering services for new and replacement HVAC systems, including:

  • Manual J Load Calculations – This step analyzes your home’s specific heating and cooling needs based on factors like square footage, insulation, and windows. It helps us avoid oversizing or undersizing your system, which can lead to higher utility bills and uneven temperatures.
  • Manual D Duct Design – This process ensures the ductwork is correctly sized and laid out for balanced airflow throughout your home. Proper duct design improves air distribution, enhances comfort, and reduces strain on the HVAC system.
  • Manual S Equipment Selection – We match HVAC systems to your home’s requirements based on the results of the Manual J calculation. This ensures the furnace or air conditioner is powerful enough to maintain comfort but efficient enough to keep operating costs low.

Premium HVAC Systems From Trusted Brands

We install high-quality HVAC systems from leading manufacturers like Carrier, LG, and Mitsubishi. Whether you need air conditioning installation for a new construction home or furnace installation as part of a replacement project, we’ll recommend the best system for your space and budget. We also offer geothermal options for homeowners looking to reduce energy use even further.

Comfort Engineered Systems has maintained a sterling reputation among homeowners and business owners along the coastal areas of Louisiana, Mississippi, and Alabama. See what our customers have to say about us.

"After using Comfort Engineering for my whole home generator I was informed that they also do HVAC.  I called them to give them a try since they did an amazing job on my generator and also the fact I've had 2 nightmare HVAC companies come out to my house just for routine service the past year.  As I suspected they a great job on my service call. Tuan was the nicest and most knowledgeable HVAC tech I've ever come in contact with. I will not be using any other company for my HVAC issues other than Comfort Engineering!!"

"The purchase and installation of my whole house generator was seamless.  The installation was very neat and professional.  The team was polite and respectful of my landscaping as well.  In addition, working with Ed on the purchase was very good - all my questions were answered timely and thoroughly.  Great job by this team.

"Contacted Comfort Engineered Systems Inc, for my air condition and heat replacement. Mr. Edward Perez came out to measure and talk about our options. We made our choice and gave him the job. His crew was very punctual and professional, and did a great job. I would not hesitate to recommend this company to my family or friends very satisfied."

"My A/C needs were met with transparency on pricing and workmanship. My technician was reliable and exhibited a high level of integrity and communication. I would definitely recommend this company."

Margaret G.

"An amazing experience. I received an in-person consultation with Mr. Perez, who was patient, knowledgeable, and transparent about the cost associated with my energy needs. My generator was installed in 2 visits (less than a month from purchase). The first visit was preparation work (pouring the concrete, setting up the natural gas line, transfer box, and wiring). The second visit was the delivery and installation of the generator itself."
