"The overall Sila team was great from the debugging of the issue, explaining the options and replacing the HVAC unit. There were multiple sila techs that helped out which we’re all great and Guy spent time explaining the new unit after it was installed and we learned a lot about our new unit."

"On time, neat, effective. Technicians were professional, personable and flexible. I gave a "B" on cost because I may have done better if I shopped around but having the company that was installing the HVAC install the electrical as well was a good convenience and one-stop shopping."

"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."

"We called during a heat wave on a holiday week when our A/C broke, so we knew it would take a while to get an appointment, especially as first-time customers. They were able to immediately schedule us for just under a week out, and let us know up top about how their services and payments, etc. work. We actually called another provider simultaneously to see if they could come earlier, but they just ended up giving us the runaround for days instead of just saying they were too busy. They confirmed a smaller time window the night before, and showed up first thing the next day. Abner was awesome, and it was such a huge relief to have someone so nice and professional, explaining everything like we didn't know anything about HVAC (because we don't). He broke down 6 options for us to move forward ranging from the minimum service fee for the cleaning all the way up to addressing everything he saw that was weighing down on the system. He explained which options we could wait on and which ones were higher priority, etc. It feels so rare to get a home service provider with this kind of professionalism these days. I wish these guys did automotive! I didn't rate them on price because I don't have a good comparison. But we will definitely be using them moving forward based on reliability, customer service, and professionalism."

"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."

Upon explaining the issue with my AC fan, they immediately understood the problem and addressed it.

Heating and Air Conditioning questions, answered by experts

It depends on the type of AC unit and the extent of the mold growth. For example, if you have a small amount of mold in your central air conditioner, it’s worth cleaning it to protect your HVAC system and your health. In situations like these, you can often remove the mold yourself in a couple of hours. On the other hand, if you have a portable AC unit with a severe mold problem, it makes more sense to buy a new one. On average, replacing a portable AC unit costs $100 to $500.

Yes, it’s normal for an AC to drip water. In fact, it’s part of the dehumidifying process that takes place inside your AC unit as the condensation trickles down into the drain pan. However, it isn’t normal for your AC to sound like it’s running water or have large puddles around it. If that happens, you can try the solutions listed above or call an AC repair pro.

Deciding whether to replace just the AC coil or the entire system depends on the age of your unit and the overall cost. Replacing a coil is less expensive than a full system replacement, but it can still be a pricey repair. If your HVAC system is relatively new and still under warranty, or if the replacement cost is significantly lower than a new system, replacing the coil can be a worthwhile investment that restores efficiency and extends the unit's life. However, for older systems (nearing the end of their 10-15 year lifespan) or those with extensive damage, it is often more cost-effective to replace the entire AC unit. Mismatched coils in an older system can lead to inefficiency and future breakdowns, so a full replacement ensures optimal performance and avoids further costly repairs.

If your home has an existing forced-air heat system, you can add a central air conditioner to it. An HVAC technician can retrofit your forced-air heating system by installing an evaporator coil onto the furnace plenum, the box next to the furnace that draws in air. Once installed, the air conditioning coils use the furnace’s blower to circulate the air.

It depends on the size of the space you’re cooling down. If you’re looking for the most affordable way to cool an entire house over a long period of time, then central air will be more cost-effective. But when it comes to cooling down a couple of rooms or one floor, a window unit may be the cheaper option, with both a lower cost to install and less energy used to run.
