"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

No. With a ventless portable AC system, you don’t need to vent anything out the window—but it will be harder to circulate the hot air from the room without one, so you’ll need to come up with another solution, like placing a fan near a warm spot and facing it towards and open water to push the hot air out.

A new HVAC unit typically adds about $2,500 to $3,000 to the value of your home or about 5% to 7% of your home’s value. Since a new unit can cost up to or more than $10,000 to install, it’s up to you to decide if the upfront cost is worth the added value. Consult a local AC installer to determine next steps.

Usually, ductwork is not included when you purchase a new HVAC system; it needs to be purchased separately. As far as installation, you’d need to speak with your local duct installer or HVAC technician directly to learn what their services include, but having your entire ductwork system replaced is likely to be more expensive than simply having your new AC unit installed without ductwork replacement.

No, it isn’t necessarily bad to turn your AC on and off frequently—contrary to popular belief. Even if you stop and start your AC throughout the day, it won’t use as much energy as it would if you ran it nonstop. 

If you’re concerned about your power consumption and energy costs, there are a few simple ways to use your AC more efficiently. Regularly cleaning the filters, scheduling routine maintenance, and using a programmable thermostat are all great choices.

Vents may blow air even though the air conditioning system is off because of the pressure difference between indoor and outdoor air or drafts from leaky ducts. Check for leaks or drafts in the ductwork or around windows and doors.
