"Very impressed with the professional appearance and demeanor of the installers. They initiated a series of pre install checks around the home that solved some issues and found a few problems that needed to be solved before they started. On top of going the extra mile, the install was successful and I'm a very satisfied customer. The manager was responsive and accommodating. Highly recommend Dunn One Hour Plumbing, Heating and Air Conditioning."

"We found SmartHouse almost by accident while looking for solutions to what turned out to be botched previous AC installation by a much bigger and more established company who we had trusted to do a decent job. Instead we ended up with a system that wouldn't cool the house. Smarthouse first correctly diagnosed the problem, then fixed it, and advised us on how best to heat and cool our 100+ old house. We now have a service contract with them for regular maintenance and they recently installed a mini-split for us. Their techs are great. Just the sort of people we would feel comfortable leaving alone in the house to finish a job if necessary."

"The engineer was thorough and professional. It rained 1.5 inches while he worked on the AC unit and it barely slowed him down. He tested, cleaned and recharged my system. Pricing was reasonable."

Air Conditioning questions, answered by experts

The decision to put your AC unit on the roof or ground depends on the climate in your area, the roof shape, accessibility, and budget. If you live in a warm climate or don’t have existing ductwork, it’s likely best to stick to a traditional AC unit that sits on the ground. However, if you lack yard space, live in a mild climate, and have easy access to the roof, your home may benefit from a rooftop AC unit. 

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.

While Freon is mostly odorless, a Freon leak will produce a faint chloroform-like smell. Some people find that Freon's odor has a subtle sweetness to it. Some telltale signs of a Freon leak beyond odor include ice crystals on your evaporator coil, bubbling sounds, and hissing noises.  

Turn your system off when you're toasty or when you're out to prevent unnecessary wear. Using the timer on your thermostat so that it switches off when it reaches a certain temperature or turns on just before you get back from work is best. An annual maintenance contract can be helpful to ensure your system receives these important services at regular intervals.

Signs that your A/C system needs professional service include increased energy bills, uneven or poor cooling, loud or unusual noises, and frequent cycling.
