"They replaced my central air conditioning and hot water heater. Great process, good people. Very patient, answered all my questions (I was an engineer, so you know there were a lot of specific and obscure questions). Not the lowest price, but when it comes to making sure that the job was done correctly (and excellently) the first time, they were very well worth it!"

Hi, I’m Lenny Guenov, owner of Guenov Comfort Solutions. I’ve spent years working my way up in this industry, starting from the ground up. My journey began in a scrapyard, armed with nothing but a saw and sneakers. From there, I installed residential and commercial equipment and eventually became a service technician.\n\nAlong the way, I’ve been covered in mud in dirt fields, surrounded by scrap metal, coated in insulation in customers’ attics, and braving snow on commercial rooftops. Through it all, I’ve learned what it truly means to work with dignity and integrity. That hands-on experience drives me to provide honest, reliable solutions for every customer.\n\nYour not just getting a technician, you’re getting someone who’s lived the work, knows the details, and brings the reliability and honesty too often missing in this industry. I’ve fought tirelessly to earn my place in this tough, rugged field. All I ask is the chance to earn my place in your home and deliver comfort for your family

I have been interested and passionate in home remodeling and decorating since I graduated highschool. There is nothing more comforting to me than a clean home and that’s why I am willing to work wherever this is an opportunity to do so. I am very passionate when it comes to helping others in any way that I can especially on my free time. I am always extra cautious about your needs and if things are to your standards. I would love to help in any way I can! 😊

"There were two crews working at the same time.  The insulation crew headed by Jim worked outside for three days in the extreme heat, the 2nd day hitting a temp of 101.  They insulated  inside and out and you would never know they were here.  They cleaned up every last scrap and vacuumed all the residue.  They were efficient, professional and  personable to work with.    The HVAC crew, Mike and Frank had to remove my cast iron furnace that the previous owners had set in cement; (the guys said it looked like the furnace was put in and the house was built around it!)  It was quite a job getting that out of my basement but, they did it!. They were also very professional, friendly and answered all my questions with courtesey and information I could understand.  They even programmed my thermostat and explained how I could change it if needed.    I now have a high efficiency heating and air con system that should decrease my energy bills to a third of what I was paying and I won't have to freeze this winter.    I would highly recommend Green Homes and will call on them again when I am ready to replace my old windows."

Heating and Air Conditioning questions, answered by experts

The standard rule for return duct sizing is that the return vent should be the same size or larger than the supply vent. This will ensure balanced airflow in your home and reduce strain on your HVAC system.

Most HVAC companies recommend against setting your AC below 70 as it could freeze up the system and cause more problems. Regardless of how hot it is outside, there is generally a 20 degree difference between the outside and inside temperatures, so even if it’s 100 degrees outside, your AC will likely not be able to cool your home to 70 degrees.

While it is possible to add Freon to your AC unit yourself, it is not recommended. In fact, the U.S. Environmental Protection Agency (EPA) prohibits the handling of Freon without a license. Freon is a dangerous gas that can cause irreversible damage to your AC or yourself if not installed correctly. It is worthwhile to hire a professional to add Freon to your AC.

To reset your air conditioner, start by turning it off at the thermostat. Then, shut off power to the AC system at the circuit breaker. Some units have a dedicated "reset" button; if yours does, press and hold it for three to five seconds. If your air conditioner doesn't have a reset button, or if you are resetting it after a power outage, leave the circuit breaker off for at least 30 minutes to allow the system to reset itself. Afterward, turn the power back on at the breaker, turn on the AC from the thermostat, and set it to "cool" to test the system.

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.
