"Robert Rutkowski of Lighyway purchased and installed two bathroom fans with light and heater! Fans are vibrating and extremely loud as to be unusable!, He did NOT enter attic but used a saw that more than likely broke off existing bracing! He the said we should have purchased better fans! We were not even given a choice!"

Heating and Air Conditioning questions, answered by experts

You should know the main components of an air conditioner: the condenser coils, evaporator coils, drip pan, AC filter, ducts, and refrigerant. Each part plays a key role in the performance and safety of your AC system. When tracking the source of AC issues or odors, it helps to know where to look. Your outdoor unit houses your condenser coils, fan, and compressor. Your indoor unit houses your evaporator coils, drain lines, and filter, and it connects to your ductwork. 

Some HVAC systems tend to use R410A refrigerant, although if you have an older model it may be using R22. R22 is banned due to its harmful environmental and health impacts, and it is a sign that your AC unit is old enough to consider a replacement and the significant efficiency gains that could come with it.

To extend your HVAC system’s lifespan, it’s crucial to keep up with maintenance. This includes changing filters and thermostat batteries, keeping the outside unit clean and clear of clutter, and lubricating moving parts. Watch out for leaks, mold buildup, and blockages to ensure your unit stays in good working order. Spotting these issues early can be the difference between a simple, wallet-friendly repair and an expensive replacement.

Yes, you can run an attic fan with the AC on. In fact, you don’t have a choice with a passive attic fan. Plus, when an attic fan draws out hot air from the attic, it helps regulate the temperature of your whole home, so your AC doesn't have to work as hard.

HVAC replacement doesn't always include ductwork replacement. It depends on the condition of the existing ductwork. You can reuse your ducts if they are in good shape, adequately sized, and meet current standards. However, if the ducts are damaged, poorly designed, or not appropriately sized for the new system, they may need to be replaced or upgraded. HVAC contractors will assess the condition of the ductwork during the replacement process and recommend any necessary modifications or replacements to ensure the new HVAC system operates efficiently and distributes air effectively throughout your home.
