"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

There are ways to detect a refrigerant leak with several different testing methods. However, most homeowners can figure out something’s wrong with their AC unit by noticing these common signs:

  • Ice forming on the evaporator coil

  • Water leaks near the AC unit

  • Frequent hissing sounds

  • Increased electric bills

  • Unit takes longer than usual to cool

  • Unit is blowing hot air

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.

Swamp coolers cost approximately 50 percent less to install than central air conditioners and cost less to run. Operation costs depend on the size of the unit and home, your climate, utility rates in your area, and the system’s efficiency. Swamp coolers use 15 to 35 percent less power than air conditioners.

Yesh, heat pumps can easily cool homes when the weather reaches over 100 degrees Fahrenheit, just as powerful air conditioners can. The key is sizing the heat pump correctly for the size of your home and your climate. A local heat  pump professional can help you determine the right size and type for your home.

Running an air conditioner with mold is not safe because it can spread harmful mold spores throughout your home. Exposure to these spores can trigger various health problems, including respiratory issues, allergies, coughing, wheezing, sneezing, itchy eyes, and a sore throat. It may also aggravate asthma in household members. Continued exposure can increase the risk of more serious illnesses like sinus infections, pneumonia, and bronchitis. If you suspect mold in your air conditioner, you should stop using the system until it has been properly cleaned to avoid health risks and further contamination.
