We are extremely pleased with the products and service provided by Air Assurance. We had our house built in 2008. After our service call on our heating system and the inspection of our ductwork, we had no doubt that replacing our system and repairing all the issues with the ductwork was the only way to go. The air quality went from 2,000,000 parts to less than 200,000 parts. The old system was pulling air from the attic into the living space. With the PSO and ONG rebates, the cost was not that expensive. We have already seen a reduction to in our heating costs. Thank you, Air Assurance.
