Hi Neil, Thank you for all your advice and help. I am grateful there is someone like you helping homeowners from AC predators.

Jennifer, Tampa Homeowner

Neil is an HVAC expert who I owe a great deal to. I contacted him through an AI search looking for HVAC design expertise. He helped me through a terrible HVAC installation and is now designing my new system.

If you don’t think HVAC design is important, I can show you my system installed 2 years ago that has mold growing in the supply plenum, an air handler that leaks so much air the system has to work extra hard to supply air throughout my house, and leaky ductwork that has basically spewed all the blown-in insulation from my attic through my house. I had that work done by a very large company that was considered reputable. Neil pointed out the list of deficiencies and code violations and helped me get all my money back. This company was not going that route initially but having people in my corner like Neil helped me achieve that win. You cannot argue with data.

Now I am working with him in designing my new system properly and am going with his recommendation for the installation. I learned that going with large companies (even with good reviews) does not ensure a successful installation. The installer I had knew nothing about Florida HVAC code and was recently promoted to manager of the install team.

HVAC Design Practices

Design

Your design will be based on the most current State of Florida codes and ACCA design standards resulting in just one HVAC math solution. Many times clients will request that the design package reflect an “impossible” math result not in compliance with the ACCA design manuals – the two most common request is to grossly oversize the cooling equipment or to use ductless mini splits for occupied spaces. HVAC Designs will reject all such requests.

It’s HVAC Design’s philosophy that when a client places an order, they expect the calculations to be thorough, complete, and correct. It’s for this reason that no corners are ever cut. Why? Because a calculation is based on real numbers and complex mathematical equations that have to match the specific building. Most HVAC contractors choose the forbidden design practice of “square feet per ton”, far short of a complete HVAC design and certainly not code or ACCA compliant, resulting in inaccurate results that never add up to a comfort system design. So don’t leave your work to chance, HVAC designs provides complete plan and spec 3rd party HVAC and ENERGY designs to ensure perfect indoor comfort.

Pricing

You may notice that HVAC Designs maintains a lower than average pricing structure compared to competitors. However, no other design company will provide a complete HVAC Design Package of higher quality than HVAC Designs. We offer these reasonable fees so that anyone can afford a professional HVAC design and accurate energy calculations.

HVAC Designs understands the importance of budgets and bottom lines. It’s for this reason that the work is correct and complete every time. The value of quality isn’t necessarily related to pricing, but to HVAC Designs, you will receive premium quality work at an affordable design fee.
