"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."

"I recently had a HVAC and water heater installation by Carroll Mechanical, Cris Lopez and his team. They were very respectful of my home and professional throughout the install. I am grateful and appreciative of working with the owner on deciding the HVAC unit to be installed. I found him to be the consummate professional, a person of integrity, transparent, responsive to my questions and willing to work with me to gain my business. I highly recommend Carroll Mechanical."

"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"

"This company came highly recommended, as many of today's technicians cannot service traditional "steam" boiler systems. Ever since last year's "furnace emergency", this "Old House" here found "its rescue match" with Pohlman Plumbing & CJ, a highly skilled specialist, who tweaked the boiler back to "steam". Explaining why my Amish-built "Oldie-Goldie" was here to last, CJ enjoyed "challenges" & was not trying to "up-sell". This positive experience of transparency & trust convinced us that we'd found "the" company for all our "Old House" future HVAC & plumbing needs, thx!"

"Technician showed the mold in the ducts and explained the process for treating the mold. When the work was completed, he then reviewed the process, showed the work that was done and explained how to change the UV lamp."

Heating and Air Conditioning questions, answered by experts

Yes. It's normal for the AC compressor to cycle on and off intermittently in dry mode as it maintains the desired humidity level. The compressor cycles to prevent over-dehumidification and to maintain a comfortable indoor environment. This cycling behavior ensures efficient operation and optimal humidity control, contributing to the overall effectiveness of the dry mode function in your AC system.

Yes, you can potentially save $60 to $200 by handling your own air conditioner capacitor installation. However, capacitor replacement comes with the risk of electric shock. Only attempt this if you have the knowledge and protective gear to carry it out safely. Otherwise, we recommend hiring an HVAC pro with the experience to properly diagnose the issue and avoid damaging other parts of your AC unit.

A 3-ton AC unit is probably too big for a home that’s 1,200 square feet. If you have a 1,200-square-foot home, you likely need a unit that’s somewhere around 1.9 and 2 tons. An AC unit that’s too large will be really inefficient and cost you a lot of extra money on your bills. 

When a compressor gets overheated in central air systems or heat pumps, it can still cool your home for a while until it eventually gives out. If the compressor is chronically overheated and no one addresses the root cause, it will create an incredibly expensive problem when your entire HVAC system breaks down and stops working altogether.

Yes, high-efficiency models reduce environmental impact with lower energy use.
