"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."

"Excellent! I love JT Dunn Heating and Cooling. We selected them out of 5 different contractors to install our brand new furnace and conditioner in 2017 and we hadn't had a problem since. We just had a 3 year tune-up and nothing was wrong and the ac is quietly humming away outside. Thanks to employee Robert Fitzgerald for coming out today and doing a awesome job and keeping us as customers!"

"I was very pleased with Ken and the team at Total Comfort. I needed a new AC and furnace to replace an old system. I was given a couple of options and chose the Amana product because of the great warranty and rebates available. The installation only took half a day and everything was cleaned up. I think I got a great price also. Thank you!"

"I was having an issue with my AC unit, called Hively heating and cooling after reading great reviews on Thumbtack. John got back to me within the hour and came to my home that evening to try to repair a very old unit. I chose a whole new system and it was installed two nights later. I would highly recommend, John was extremely professional as was his crew, He kept me well informed every step of the way. Great job!!"

"Our house is 60 years old. We have lived her 42 years, this the first time we have had the ducts cleaned. The air in the house just seems lighter, the biggest thing is we have a black glass top entertainment center in the den. U could clean and 2 days later it was dirty again. We had this done2 weeks ago, it just now needs cleaning. We are very happy with the results. Would highly recomd it. Also vent centers is a filter company with wonderful filters for your air ducts. Ventcenters.com we put them in all our registers"

Air Conditioning questions, answered by experts

Unfortunately, a freon leak will persist even when your AC unit is off. The freon in the AC unit is under pressure no matter the status of the system, so it will continue to drip through the leak even when you shut off the entire unit. It will continue to leak freon until it’s completely empty.

If you’re shopping around for a rooftop AC unit, you may hear them referred to as “package units.” That’s because rooftop AC systems are all-in-one heating and cooling units that connect directly to your home’s ductwork. If your AC repair pro references a package unit, they are referring to the system on your roof.

The cost to install a ductless mini-split AC system ranges from $2,000 to $14,000, depending on the type of unit, the number of zones or rooms, and the complexity of the installation. On the low end, a system for one or two zones in a single room costs around $2,000. Covering two zones for more rooms can cost between $6,000 and $8,000. For a larger multi-zone system to cover an entire home, costs can be $14,000. If you don’t already have an AC system in place, you may need to add the cost of permits, an electrician, and a concrete pad.

Yes, a mini split AC system can replace central air—and quite easily, too. Since mini splits don’t require ductwork, homeowners can convert their central air system to a mini split to save money and energy. Consult with an HVAC professional to learn more about the process of replacing your central air with a mini split.

The difference between a home surge protector and an HVAC surge protector is that an HVAC surge protector is designed to protect the components inside your HVAC unit while a home surge protector is installed near appliances and meant to protect your entire home. There are three tiers of whole-house surge protectors, and they are more expensive to install than HVAC surge protectors.
