My name is Jay Scannell and I enjoy cleaning and making things spotless. My mother always made sure our house was clean as I was growing up and naturally I have liked to follow those similar footsteps and take it that one step further. I’d enjoy cleaning for you and your family if need be and I am open to anything you throw at me:).

Heating and Air Conditioning questions, answered by experts

No. HVAC, which stands for heating, ventilation, and air conditioning, includes all of the systems that work together to regulate a building’s temperature and humidity levels. In comparison, air conditioners only provide cooling. You can have an air conditioner as part of your HVAC system, but not all HVAC systems include air conditioners.

If you don't clean your AC evaporator coils, dirt and debris will build up, which impairs the system's ability to transfer heat. This forces the unit to work harder, leading to inefficient performance, higher energy bills, and frequent breakdowns. Over time, neglected coils can corrode, which may cause refrigerant leaks, or develop mold, ice buildup, and a clogged condensate drain, resulting in poor air quality and an uncomfortable home.

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.

When your HVAC system is loud, a few different causes are possible. If you have loose connections or bolts in the hardware, they can rattle as the system runs and vibrates. If you have an extremely dirty furnace filter, it could cause the system to generate noise. More commonly, an excessively loud HVAC system indicates a malfunction in the system. You may have a blower motor that is close to failing or a compressor that is breaking down. These issues require an immediate inspection.

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.
