"This company went above and beyond to help us. Our furnace stopped working and we had no heat at all. We called them and Brian came out the next morning and gave us a quote on the spot. Four days later they installed our new furnace and had us up and running in no time. I would heartily recommend this company. I know I will call them again if I have any problems in the future!"

"Mike and his team were very professional and they even finished a day early. I was totally impressed with the extra care they took in locating the air handler off to the side in the attic. All the vents look beautiful and I'm so glad I went with the central A/C. Thank you Mike and the whole team."

From start to finish each employee was personable, extremely knowledgeable, very courteous, and the consummate professional.

Heating and Air Conditioning FAQs, answered by experts

The American Society of Heating, Refrigerating, and Air-Conditioning Engineers, or ASHRAE, sets the standard guidelines for air changes per hour in homes and businesses. The International Residential Code, or IRC, also sets ACH requirements for residences and bases those requirements off of ASHRAE standards plus climate specifics related to your location.

A home AC unit provides anywhere from one-half to five tons of cooling and requires approximately two to four pounds of refrigerant per ton of cooling. At approximately five to 10 minutes to fill one pound of refrigerant, a home that requires three tons of cooling will take about six to 12 pounds of refrigerant and approximately 30 minutes to two hours to completely recharge the unit.

Yes, you can put an AC unit on the roof of your home or commercial building. For proper installation, you’ll need to ensure the roof surface is flat, it’s accessible for maintenance and cleaning, and an AC installation pro agreed that your home is a candidate for package units. Don’t forget to consider the climate in your area, as homes that experience frequent tropical storms or hurricanes may not benefit from this type of system.

Yes, government incentives and programs are available to encourage energy-efficient upgrades in many regions. These incentives may include tax credits, rebates, grants, and low-interest loans for homeowners who invest in energy-efficient improvements such as HVAC system upgrades, insulation, and efficient windows. The availability and specific details of these incentives can vary by location, so check with your local government or utility company to explore your options.

A non-maintained AC is more likely to perform poorly, increase your energy bills, and undergo more severe issues like breakage and water damage. That’s why DIY cleaning or professional maintenance is recommended annually. Otherwise, you might end up paying more in the end than you would for annual service. You can purchase cheap AC cleaning kits if you prefer going the DIY route.
