"The inspection turned into a new furnace and air conditioner. I decided to take advantage of their special of $1000 off if you replace both. Mine were old enough so that I decided to replace rather than repair. Technicians were very pleasant, knowledgeable, and professional."

"Great to work with. They were efficient and knowledgeable. They took care of the rebate for our heat pump. Only thing lacking was responsiveness to email/phone communication after the install was done. Heat pump system is working great."

"Technician Jim was not impressive. Was not confident when answering the questions I asked. Very contradicting.. Tried to sell product for items that were not even in need of repair. Spoke negatively about the company and made excuses as to why he could not perform his job due to lack of information from dispatch or technician manager. Said he would follow up, I never heard from him. Blessing to me, I decided to go with another HVAC company. I typically would not put names out there, but please be careful if you get this gentleman as a technician."

Exhaust Fan Installation questions, answered by experts

Fan power is measured by CFM, or cubic feet per minute. For every 1,000 feet of square footage in your attic, you need a minimum of 700 CFM. Steeper roofs may need larger fans or about 840 CFM.  You can figure the size of attic fan you need by multiplying the square footage of your attic floor by 0.7. (multiply by 1.2 for a steep roof and 1.15 for a dark roof). That number is the CFM required for your fan to run efficiently.

Regular cleaning, sealing ductwork, and ensuring proper airflow paths keep systems functioning optimally, maintaining energy efficiency.

If your fan is ceiling-mounted and will vent through the attic to the outside, you will need an electrician to handle the wiring, and if you need to install ductwork for the first time or replace existing ductwork, you will need an HVAC professional as well.

Your bathroom exhaust fan shouldn't be loud. However, bath fans come in a wide variety of models, price points, and loudness characteristics, and yours may be louder or quieter than others you notice. Economy models tend to be the noisiest, with levels of 4.0 sones or more, which is about the sound of an electric shaver, while some high-end models can be barely audible. 

DIY is possible for basic replacements. Professional installation ensures proper wiring and venting.
