"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

Heating and Air Conditioning questions, answered by experts

It is normal for the attic to be hotter than the rest of the house in the summer, but only by about 10 or 20 degrees. Attics that aren’t properly insulated or ventilated can reach temperatures of 130 degrees or more which can cause damage to the home’s structure, including the roof, wood framing, and HVAC system.

There are many recognizable symptoms of AC compressor failure. They include loud banging noises, hot air being continually circulated in your home despite running the AC at full blast, uneven airflow and cooling, and electrical issues like constant surges due to the compressor working overtime. While some of these symptoms, like uneven cooling, can have other root causes, they are common indicators of compressor problems.

Choosing a unit with higher BTUs can use more electricity if the BTUs are more than what’s necessary for your room size. However, choosing an AC with BTUs that match the size of your room or house, your unit will cool your space efficiently. On the flip side, choosing a system with not enough BTUs can cause the system to work harder to try to cool the space, leading to more electricity consumption and higher energy bills.

Yes. Getting a whole-house dehumidifier can help you save money on energy bills. How? Your home automatically feels cooler when there’s less humidity in the air (“It’s the humidity that gets ya!” is such a true statement). This means that you won’t need to run your AC as much as you would if you had all that extra humidity in your home.

Yes, government incentives and programs are available to encourage energy-efficient upgrades in many regions. These incentives may include tax credits, rebates, grants, and low-interest loans for homeowners who invest in energy-efficient improvements such as HVAC system upgrades, insulation, and efficient windows. The availability and specific details of these incentives can vary by location, so check with your local government or utility company to explore your options.
