"Don was able to fix several problems, including my washing machine whose water would not stop rising and replacing an out of code electrical outlet. Bizarre electrical problems cropped up with both the washing machine fix and outlet replacement while he worked on them, but he persevered and was able to figure them out and resolve the problem. Don is very friendly, gives advice about products when asked, I would recommend him to others."

"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! 😊

Heating and Air Conditioning FAQs, answered by experts

If you know how to identify supply and return ducts, you’ll find that only the supply ducts will have dampers. Although your return ducts can have dampers, it’s not common. If you have one return duct that is pulling in too much air, adding a damper to it can help with overall system performance. However, dampers on return ducts are not a necessary addition for most homes.

The cost to replace an AC unit averages around $5,900, with a typical range between $3,900 and $8,020. The final price depends on several factors, including the type and size of the air conditioner, its efficiency rating, your geographic region, and labor costs for installation. Smaller units like portable and window ACs are much less expensive, costing between $90 and $550, compared to central or ductless systems. If your current unit is less than 10 years old, repairing it may be more cost-effective than a full replacement.

You can adjust uneven airflow in your home by adjusting the dampers on the vents. However, if the temperature feels consistent throughout the home, don’t worry too much about uneven airflow. Generally speaking, larger rooms should receive more airflow than smaller rooms, especially if they only have one vent.

On a summer day, expect your AC to run between 12 and 16 hours. However, this time frame depends on just how hot it is outside and the comfortable temperature you’re hoping to maintain indoors. Assuming the size of your AC is appropriate for the space you’re trying to cool, it shouldn’t be a problem for it to work this many hours.

The length of an AC cycle depends on the settings in your thermostat and the unit you have. Central AC doesn't constantly run at full blast the way that a window unit does. A cooling cycle in most homes is 15 to 20 minutes. Then, the unit stays off for seven to 10 minutes to circulate the cold air in the house before the cycle repeats. It should repeat two or three times per hour. A short cycle lasts less than 10 minutes and then turns off.
