"I purchased a Deal, spoke with Ken, the owner, and he was flexible about my schedule changes (due to the tile job taking longer). Since a crew was running behind, he came himself to do the work late in the afternoon knowing that I needed the vent cleaning that day before we moved in. Ken did an amazingly through job of cleaning and disinfecting, and shared his knowledge about HVAC systems and duct routing the whole time. He analyzed our system capacity, checked the duct routing in the attic, and gave us options for improving our HVAC system in future when the existing equipment is ready for replacement. So not just a simple service - an informed future strategy! Can't say enough about how impressed we were with A Breath of Fresh Aire, we will definitely use their services again."

"Dear Coast to Coast Heating and Air Conditioning, I am writing to express my sincere appreciation for the exceptional service provided by Scott and Anthony during the installation of our new unit today. Throughout the twelve-hour process, both gentlemen demonstrated remarkable professionalism and technical expertise. They took the time to answer all of our questions thoroughly, ensuring we were fully comfortable operating the new system before they departed. We were particularly impressed by their dedication to detail and their commitment to our home's safety and comfort. We also appreciate the clarity provided regarding our agreement, including the 10-year parts warranty and the three-year service maintenance plan. Knowing that Coast to Coast will provide ongoing support to ensure healthy air quality in our home gives us great peace of mind. Scott and Anthony are a credit to your company and deserve recognition for their hard work and kindness. Having lived in Evergreen Estates ."

"Leahy Heating & Air Conditioning did an excellent job with our HVAC installation. From the beginning, they were honest, professional, and easy to work with. The pricing was fair and clearly explained, and we never felt pressured or pushed into anything we didn’t need. The install was clean, efficient, and done with great attention to detail. I would highly recommend Leahy Heating & Air Conditioning to anyone needing a new AC system, heat pump installation, or HVAC service in Gainesville and the surrounding North Central Florida area."

"Very professional, did the work in one day, they are coming back for duct work. Our old AC was 21 years old and had never been serviced. They put in a brand new system and it was working the same day, thank you! Expensive because we had to replace the whole HVAC system, but has great quality for the money, thanks!"

"Very accommodating. Crew was professional and friendly. They replaced my entire HVAC system including ducts and supply vents in two days. Scheduled so we had air overnight and were almost invisible and silent. Hardly knew they were there."

Heating and Air Conditioning FAQs, answered by experts

The size window AC you need depends on the BTU and the size of the room you’re cooling. For a room with 8-foot ceilings, look for about 20 BTU per square foot of the room. For example, a 12-by-12-foot room should have an air conditioner with 2,880 BTU. You can buy something slightly more powerful, but don’t overshoot the BTU for a small room, or you’ll waste energy and have higher bills.

On a summer day, expect your AC to run between 12 and 16 hours. However, this time frame depends on just how hot it is outside and the comfortable temperature you’re hoping to maintain indoors. Assuming the size of your AC is appropriate for the space you’re trying to cool, it shouldn’t be a problem for it to work this many hours.

The general rule of thumb for figuring out how much AC tonnage you need in your home is that for every 500 to 600 square feet of space you need to cool, you’ll need one ton of AC cooling power. So, a 1,000-square-foot home will need 2 tons of AC power. 

Water buildup in your HVAC system is a cause for alarm. If water accumulates in your ductwork, it can drastically lower your home's air quality and create safety hazards. These risks include mold growth, damage to your HVAC system, and attracting pests that are seeking water into your ducts. Proper insulation and sealing of ducts can prevent this, and regular inspection and maintenance can address water damage problems before they become too severe.

The standard rule for return duct sizing is that the return vent should be the same size or larger than the supply vent. This will ensure balanced airflow in your home and reduce strain on your HVAC system.
