"The appointment was made within 2 days of contacting them. The technician (Brian) was punctual for a 7:30 am appointment. Once there, Brian did a fantastic job of communicating the services that he was performing and kept me very informed about the status of the AC system. He found some issues that had been previously overlooked by former HVAC technicians and provided me with a very detailed understanding of what the outlook for my unit should be in the future. I noticed an immediate improvement in the cooling of the house as well as the air quality. I can't thank this company and this technician enough for being so professional in the way they conduct their business. I would recommend them to anyone in need of HVAC service."

"From receiving the quote to the installation and servicing NETR has been extremely professional and great to work with on this renovation project. The installation went very smoothly and every person on their team had a lot of experience. Further, the team was able to solve a number of tricky problems with our installation (such as running the electrical behind the walls, drilling a hole through the roof for the pipe, concealing the pump in the back of the closet). The installation happened on time and on schedule. I would highly recommend them to anyone looking for HVAC services at home."

"I called the company on Sunday evening and they responded promptly early in the morning. My system was installed by them 3 years ago but somehow I missed last year's annual servicing. With the current heat wave it was severely underperforming. They sent out Robert Duclos within the hour. He diagnosed the problem---not enough Freon in the system, grass and mulch build-up in the compressor, valves buried under the landscaping--and fixed it all for the price of the annual service contract. I would definitely recommend them for anyone needing central a/c work."

"I have nothing but good things to say about Philip Mills, his crew, and his company, Cassana HVAC. I wanted to install heat-pumps for central heat and air in my large home, and I solicited a few bids. Philip responded promptly to my request to visit my home and provide a detailed estimate. His price was quite competitive, the work started on time, and he and his crew did an excellent job. Indeed, I am so impressed with Cassana HVAC that I am now using them to work on other systems in my home. I highly recommend Philip Mills."

"My electrician from Cotti-Johnson HVAC was a master electrician. If you get him, you are getting the best. I went with the most expensive work package of the 3 that were presented. First off, it was pricey. I knew that going in. I want Cotti-Johnson to understand that I am serious about a working relationship with them. I feel I have done that with their electrical department. Now, if I need their plumbing or HVAC service, our relationship can build off the first experience."

Heating and Air Conditioning questions, answered by experts

Running a window air conditioner unit costs about $0.06 to $0.88 per hour. Choosing the correct size air conditioner can help it run more efficiently.

Replacing both an AC and a furnace takes a full day on average, ranging from eight to 12 hours. The process involves removing the old units, installing the new ones, and ensuring all connections are properly made. If both systems are being replaced simultaneously, it can take longer than installing a furnace alone, so plan accordingly.

The average cost to replace or install a new HVAC system is around $7,500. However, the price can range from $5,000 to $12,500, depending on factors like the size of your home, the type and brand of the unit, and your specific heating and cooling needs. If you only need to replace certain components, the cost will be lower; for example, a new AC unit can cost between $2,200 and $5,500, while a new furnace costs $3,200 to $6,000. If additional work like new ductwork is required, the total cost could be as high as $22,000. It's best to contact a local HVAC company for an accurate quote.

It’s critical to use the right size AC for your space and not go too small or too big. If you purchase an undersized unit, it won’t properly cool your house, and it has to work harder to reach the optimal temperature. This will eventually wear your unit out. An oversized unit can spell trouble because it will turn off and on more frequently, which also wears out your AC unit. An oversized unit also causes humidity in the home.

If left untreated, a frozen AC unit can lead to costly damage, especially to the compressor and evaporator coils. When ice forms on the evaporator coils, they become brittle and more susceptible to breaking. Plus, a freeze makes your AC system much less efficient, which means it's wasting energy and costing you more in your monthly energy bills.
