"When we need work done on the house we always call Bob @ Phalan Construction. My husband and I are very picky about the quality of work and Bob has always done a top knotch job. The most recent project was the re-tiling of a small second bathroom. The floor was very uneven which caused the toilet to leak. Bob completely gutted the bathroom floor and started over making it a new level surface. The tile came out great and he reinstalled the toilet which now does not leak or run! In addition, while there, we decided to have Bob replace some interior doors that were in rough shape and paint them. Again, did a great job. AND, we also had Bob install a tile blacksplash in our kitchen. The great thing about having Bob do the work is that he can do everything, we don't need to have multiple contractors, just one person that we can count on."

"Installed two heavy window air conditioners, lugging them up from garage under to first floor. Appt was scheduled for 9:30 am, called them at 10:15 and unfortunately the owner had had a very bad night with his mother in hospice care. Finally came at 11:20. They were willing to wear masks inside our house. Installation went very quickly and smoothly. They knocked $25 off their usual minimum hourly rate because of the delay. Very friendly, would definitely hire them again (and probably will for A/C removal in the Fall). Would have been 5 stars except for the arrival delay."

"Lisa and apprentice arrived early and got right to work. The job was not as straight forward as I had believed. After much study, Lisa developed a plan and executed it to perfection. There was excellent team work and no wasted effort or time. The result was great and even though they used contractor supplied parts, they honored their original price. At the end, they thoroughly tested their installation and did a great job in cleaning the area. A light fixture had been dropped and they volunteered to replace it if there was any problem with it (there wasn't). Overall, I was very satisfied with all aspects of this job."

"I had Joe mount a TV on my wall. He was resourceful trying to figure out the best way to do it. He was accomodative as he went to the store to pick up extra parts. And he was very professional. He responded quickly to my call, showed up early to the job and completed the job very well. I would definitely recommend him to my friends for any number of projects."

Bathroom 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.

Attic and whole-house fans improve a home's energy efficiency and comfort. They ventilate hot air from the attic, which reduces peak cooling loads, lowers reliance on air conditioning, and decreases indoor temperatures. This improved air circulation and expedited heat exit helps lower cooling costs, balance moisture levels, and enhance overall natural airflow, contributing to the efficient operation of other home equipment.

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. 

The square footage of your room will dictate the correct ceiling fan blade size. For example: 

  • Rooms smaller than 75 square feet require a fan that is 29 to 36 inches.

  • Rooms up to 175 square feet require 42- to 48-inch fans.

  • Rooms up to 350 square feet require 52- to 56-inch fans.

  • Expansive spaces over 350 square feet need a fan larger than 60 inches.

The most efficient ceiling fan height is 8 to 9 feet from the floor to the fan blades. For ceilings higher than 9 feet, a downrod can be used to lower the fan to the optimal height. This positioning ensures adequate air circulation and maximizes the cooling effect. Remember, fans should be installed at least 7 feet above the floor for safety.
