"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

No. Your furnace does not run your air conditioner. Both units use the same system of ductwork to move conditioned air throughout your home, but you can have a furnace without having an air conditioner and vice versa. Furnaces are only for heating your home. You can buy a system that does both, however, like a split system or a heat pump (yes, heat pumps cool, too).

AC leaks are common, and an HVAC pro can usually fix them. You may be able to resolve some leaks on your own, but a professional HVAC technician should handle most AC leak repair. If left ignored, an AC leak could cause serious damage to your system or leave you with expensive water damage, usually leading to more costly repairs or replacements.

HVAC companies may charge an hourly rate or a flat fee. Hourly rates typically range from $100 to $250 per hour, with an average around $175. Some contractors charge a flat fee for specific services, such as an inspection, which can cost between $150 and $500. The total cost of an HVAC service is influenced by several factors, including: the urgency of the service (emergency repairs after hours or on holidays cost more), the time of year, the type, size, and brand of your HVAC system, the specific repair needed, and whether you have a service contract.

If your home has an existing forced-air heat system, you can add a central air conditioner to it. An HVAC technician can retrofit your forced-air heating system by installing an evaporator coil onto the furnace plenum, the box next to the furnace that draws in air. Once installed, the air conditioning coils use the furnace’s blower to circulate the air.

Yes, it's normal for air conditioners to leak tiny amounts of water due to condensation. Under normal circumstances, all excess moisture travels to the drain pan to be pumped through your system's drain line. You should call a technician to diagnose the issue if you're noticing frequent leaking or pooling. It's also important to investigate if your homeowners insurance can cover water damage.
