At G&J we offer Manual J and Manual D's in the Maryland, DC and Virginia area primarily and have over 12 years of experience in the residential HVAC Design industry. G&J has been doing work all around the DMV and even designing as far North as New York, and as far West as California. We specialize in the requirements of counties such as Baltimore, Howard and Montgomery. We also offer permit expediting services so that you don't have to deal with the counties yourself. Our prices are $300 per system for the Manual J and Manual D duct design. If you only need the Manual J without the duct design it is $200 per system. Our designer has taken multiple training courses with Wrightsoft, and also completed ACCA training.
