I want to speak highly of A-Advantage as our HVAC service provider. We have been in our single family home for 16 years. The first ten years we had 4 different HVAC services - due to unprofessionalism, untimeliness, overall service. In 2009 we were told by our service provider that the return duct to our unit was not providing the air properly and that it should be re-ducted. I brought in half a dozen HVAC services on this issue and received a number of response to it'll cost $2K - $3K to we won't do it. When I called A-Advantage, they sent out Mike, their head service manager, and he gave me an answer that none of the estimators offered - do nothing at this time. He stated that investing in the existing unit may not solve our short cycle issue for the air conditioner. He did a calculation and determined that the contractor who installed the unit put in an oversized air conditioner and that to do it right, we would need to do a complete load test on the house and probably install a whole new system. The reason we should do nothing is that for the most part the system operated fine for us and to put the money into a re-duct job would be a waste of money, since when it would be time to replace the system, they would just take it out. This for me was a breath of fresh air. Since that time we have used A-Advantage as our HVAC service.
This winter we decided to look into installing a whole house natural gas generator. To confirm that we had enough gas service to the house, we contacted the Washington Gas marketing department on 15 February 2013. We were told that we had enough service to add a 20KW Generac system to our house. With this information in hand, the we decided to proceed with the installation of a generator system and to replace the 10 year old hot water heater that needed to be removed for the contractor to run the gas lines to the generator.
A-Advantage was one of the 3 contractors we called for an estimate. This time we dealt with John who provided us with thorough information for the project and he was very helpful and timely in providing us an estimate for the work to be done. One thing that we found unusual was that there were no incremental payments in their proposal. It was a pay in full contract once we passed the final inspection by the Fairfax City Code Administration inspector. As much work as we've had done on our house, this is not the norm.
Due to a delay in delivery of the 20KW Generac system and the weather, A-Advantage started the job 8 1/2 weeks after the paperwork was submitted to Washington Gas. This installation went very smooth, day 1 - electrical installation, day 2 - gas line work, day 3 - inspection and fix gas leak, day 4 pass gas pressure inspection (no work done), day 5 do generator test (1/2 day), day 6 final inspection by City Code Administrator.
We are very happy with the work and professionalism of A-Advantage and would recommend them to anyone who lives in the Northern VA/DC/MD area for HVAC work and if they are considering installing a natural gas generator. read more
