Since 2012, Air Tech has offered quality services with professional attention that our clients deserve. Contact us to know more about Air conditioning repair service.

"We will never use this company again. They were not upfront on their labor charge for a part under warranty and then threatened us to send us to collections when we asked to meet them half way. They also tried selling us an air scrubber yet neglected to tell us the reason we are having a mold issue is because the seal between the house and the unit has holes in it. They also did not put back things moved to get to the unit and crawl space. It is unfortunate that there are companies out there who choose to do business in this manor."

Energy Efficiency Auditing questions, answered by experts

The extra insulation helps reduce energy costs by minimizing drafts and temperature exchange between indoors and outdoors.

Blower door tests are measured in a few different ways, but the most popular are air changes per hour (ACH) and cubic feet of air (CFM) moving through the house per hour. A good ACH score is less than 2ACH, but 1ACH is better. This means the house experiences a total air change within 60 minutes (for 1ACH). For 2ACH, there’s a complete change every 30 minutes, and so on. CFM scores are similar in that a lower score means less air change, and therefore less leakage.

Leaving lights on raises the electric bill, but not as much as having high-wattage light bulbs. The best way to save on electric costs is to swap your light bulbs to LED or CFL bulbs that use far fewer watts. You can also use smart lights and light switches to control usage via a smartphone or voice-controlled device.

Modern windows provide enhanced UV protection, improved heat retention, and cooling efficiency, contributing to overall household energy savings.

The best way to save money on home heating oil is to get large deliveries in the summer months when the prices are lowest. However, this method will only work if you have a separate storage tank or an unusually large primary tank. You can sometimes save money by opting into a delivery contract, as some companies offer set prices that they believe will sit at the average cost over the contract term. If the price of oil rises, you could enjoy some savings, but keep in mind that you might also pay a bit more if the price decreases.
