"Really fast and professional service when our HVAC broke in the peak of summer. Had it up and running in almost no time. My advice to first time homeowners like me in these cases is to always make sure you know what repairs and actions are being done. It'll help in regards to money."

"One of my AC compressors was not starting correctly every time. If it did start, it would run fine, but on hot days, when it would cycle frequently, (i.e. cool to target temp, stop, temp would heat up, thermostat would send signal to restart, and eventually the compressor would not restart). I don't remember the exact explanation, but I think there's a small fan linked to the capacitor. The fan provides some cooling to the capacitor which is stressed at startup time. Eventually the capacitor burned out because it wasn't getting its appropriate fan/cooling. First, this is a pretty specific problem. I'm fairly technical myself, and my father can fix anything. We had isolated the issue to the capacitor, but could figure out why it had failed. This is a large home and the large capacitor, so it really was a job for a professional -- capacitors offer plenty of opportunities to electrocute yourself pretty severely if your a "do-it-yourselfer." The No-Frost tech diagnosed the problem within a few minutes and explained it in detail. I called my old man to see what he thought, and confirmed that would definitely explain the problem. Second, the appropriate replacement part was an all-in-one capacitor/fan combo part specifically made by the vendor. Because my unit was a larger-than-typical unit AND these guys rushed out pretty much same day (or next morning -- I think it was a Friday going into a 95 degree weekend). The tech didn't have that exact part on his truck. He gave me two options, he had the same size capacitor and fan unit separately, so he could merge those together and get the unit functioning right then and there, or he could order the part and come back some time the following week -- he called the warehouse and they didn't have it in stock (my compressor is large and 10-years old). Given the weather, and everything else, I had him build the setup I needed, took him about 20 minutes to link the fan and capacitor together and the AC unit was humming along again shortly thereafter. I loved that he took the time to explain the problem in detail. He could tell i was "tinkerer," yet he was very politely patient with my ignorance (I had no idea the capacitor required its own cooling). I loved that he gave me the choice on waiting for the vendor's "officially sanctioned" part or just getting the unit working, and that he took the time to explain why this wasn't a risky workaround. I gave him a nice tip and emailed my neighborhood HOA email group the contact details as a reliable, trustworthy and well-priced service provider who will always go the extra mile for the customer. These guys fixed my furnace a year earlier when I nearly burned my house down by not paying attention to my intake... Would and have definitely recommend these folks for any HVAC needs."

"Victory HVAC installed 2 mini splits for me. Great communication, they showed up when they said they would, the job was completed in one day. They worked with me regarding placement as well as advice what brand to buy. Excellent service, reasonable price, they cleaned up when done and were very easy to work with. Yossi is extremely knowledgeable about all things HVAC. Super nice guy to boot. I will definitely use Victory HVAC for all my HVAC needs in the future. 5+ stars"

"I couldn?t be happier with the experience. Graham Solution handled the entire installation from start to finish, and the quality of the work was outstanding. He was professional, knowledgeable, punctual, and paid close attention to every detail. The installation was completed efficiently, everything was left clean when the job was finished, and the system works perfectly. It?s hard to find someone who takes this much pride in their work, and it definitely shows. I highly recommend him to anyone looking for reliable, high-quality HVAC installation. Excellent workmanship and great customer service from start to finish!"

"I called Carroll Mechanical for an estimate on a new high efficiency heat pump system. I met with a member of their team that clearly explained everything and helped to design a solution that worked for my family at a fair price. The install team arrived on time, they were very polished, and did a technically excellent job. The system is working really well and the whole family is comfortable! Couldn’t have asked for more - I’ll be using Carroll Mechanical as my go to HVAC contractor from here on out."

Heating and Air Conditioning FAQs, answered by experts

Yes, mini-split or ductless AC systems add value to a home and do not devalue it. They are an attractive feature for potential buyers, especially in older homes without existing ductwork, as they provide a practical air conditioning solution without the significant expense and hassle of installing traditional ducts. Ductless systems also eliminate issues associated with conventional ductwork, such as noise and the potential for pests. Furthermore, homeowners value energy-efficient solutions, and mini-splits offer high efficiency for both heating and cooling, plus zoned temperature control. This leads to lower energy consumption and reduced electric bills, which is a major selling point.

A dual evaporator coil is a specific design that allows the AC system to cool different compartments at different levels. It’s usually seen in refrigerators and similar appliances, but not in whole-house air conditioning systems. Talk with your AC technician about the best uses for a dual evaporator coil.

You should get anywhere from three to five quotes for HVAC replacement to get an idea of the average cost of a new unit. Although this quote-collecting process can be time consuming, it allows you to compare what work is required, what type of unit you should install, and how much you should expect to pay for the service.

While personal preferences widely vary, sleep experts say the best temperature for sleeping is between 60 and 67 degrees Fahrenheit rather than 78. If you do choose to sleep with your AC unit tuned to 78 degrees, you might want to use only a sheet or light blanket rather than a comforter. You might also consider installing a window unit in your bedroom so that you can be cooler in bed without wasting energy cooling the whole house.

If you know how to identify supply and return ducts, you’ll find that only the supply ducts will have dampers. Although your return ducts can have dampers, it’s not common. If you have one return duct that is pulling in too much air, adding a damper to it can help with overall system performance. However, dampers on return ducts are not a necessary addition for most homes.
