"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!!"

Heating and Air Conditioning questions, answered by experts

If possible, avoid placing furniture in front of a return air vent. A blocked air vent can cause your HVAC system to use more energy, which in turn can lower the life span of your unit and raise your energy bill. Furniture can also trap hot or cold air, damaging your furniture or appliances. 

Professional duct installers suggest leaving between six and 12 inches of space in front of an air return vent. If you must place furniture in front of a return air vent, try to aim for putting furniture over a floor vent instead of in front of a wall vent, and avoid draping curtains over any vent system.

The higher the BTU rating an air conditioner has, the more effective it can be at cooling your space. It will cool off your room faster in the short term. However, over the long term, if the unit has too many BTUs for the space, it can wear down the unit faster and shorten its life span.

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.

Fall and spring are the best times of year to purchase an air conditioner, furnace, or other HVAC components. In fact, by shopping during these periods, you could save 10% to 15% on an AC unit. For HVAC professionals, spring and fall are less busy than summer and winter, when extreme temperatures create an urgent demand for heating and cooling.

Choosing between a ductless mini-split and central AC depends on your specific needs. Ductless mini-splits are ideal for targeted cooling, providing zoned comfort and energy efficiency. They are perfect for smaller spaces or homes lacking ductwork. In contrast, central AC offers consistent cooling throughout the entire house but requires ductwork and may be less energy-efficient for smaller spaces. 

Consider factors like budget, home size, and cooling preferences to make the right choice. Combining both systems, with a ductless mini-split in specific areas, can also be a viable solution for tailored comfort and overall efficiency.
