"To be truthful i was very skeptical hiring anyone to put on a new deck because of all the horror stories you hear of contractors taking your deposit and never returning to finish the job. BUTâ ¦ meeting with Jacob Quick made it all very easy. I met with Jacob many times because of my apprehension and having issues with making decisions. After signing a contract, Jacob kept in contact with me on starting date, permit issues, when materials would be delivered, and if there was inclement weather conditions that they could not work that day. From the start of teardown to the finished project, they were there every day at 7:30, making sure that time was ok with me. They had a crew of 4-5 people working all day. When an issue came up, they were up front and we discussed it. I felt very relieved that all the guys were very knowledgeable and experienced. I am picky when it comes to details and the entire crew were all very concerned about the littlest details. Brian was also great at answering my questions as the deck was being built. They wanted me to be highly satisfied and i surely was. Not only did they do an outstanding job building the sturdiest deck around but when they left my house, you couldn't even tell they were thereâ ¦ my yard was clean. Soâ ¦ yes i would hire them again. They made the entire experience easy peasy for me. Also kudos to the other guys on the team who also worked their butts off in the 100 degree weather. Put your mind at ease and hire Jacob Quick with Master Remodeler. You can come by and check out my deck!!"

"I recently had the pleasure of working with Middle Water LLC for spray foam insulation on a client's home and was thoroughly impressed by their professionalism and quality of work. The team consistently showed up on time and adhered strictly to the bid they provided, showcasing their commitment to reliability and integrity. Their dedication and work ethic, particularly the impressive contributions from the hardworking Amish labor, were remarkable. Based on this experience, I have confidently referred Middle Water LLC to another client, who is now planning to use their services as well. The excellent job they did, combined with their punctuality and adherence to the bid, make them a standout choice for insulation services. I am so satisfied with their work that I intend to use them for my own home, which I plan to build in the near future. Middle Water LLC has earned my highest recommendation for anyone seeking top-notch spray foam insulation for their home or business."

Heating and Air Conditioning questions, answered by experts

Yes, technicians check refrigerant levels, loop performance, and system calibration for peak efficiency.

There are several steps you can take to prevent your AC drain from clogging. This includes cleaning the drain line at least every three months, changing the filter every one to three months, and getting your AC serviced annually. Also, if any problems arise with your AC, hire an HVAC technician to deal with them ASAP.

ACs don't run on water. They're not connected to drain pipes or any part of your plumbing system. However, they need refrigerant to run. Refrigerant is a gas or liquid that has a low boiling point and absorbs the heat in your home. ACs need this in order to be functional and cool your home. If you suspect your AC is low on refrigerant, you need to contact a licensed HVAC professional. Refrigerant is a dangerous chemical that requires specialized training and permits to work with. 

A dirty air conditioning coil can cause your unit to work overtime, leading to reduced efficiency, higher energy use, more wear and tear, and possible ice buildup. If the coils corrode, refrigerant can leak, causing damage, possible mold growth, and an expensive repair bill. By cleaning your AC coils once a year, you’ll have a more efficient unit that’s likely to last longer.

Yes, having mismatched evaporator and condenser coils in your AC system can lead to serious issues. For instance, it can result in higher monthly energy costs as the system runs longer to compensate for the mismatch. This mismatch can also put extra stress on the system, compromising its efficiency and longevity. 

Along with that, mismatched coils can lead to higher temperatures and humidity levels in the home. What’s more, using coils of different sizes may violate the manufacturer's warranty, as they are designed to work synergistically, and any mismatch could lead to repairs and system failure.
