We take pride in delivering value through top quality work with excellent prices.

"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

Some HVAC systems tend to use R410A refrigerant, although if you have an older model it may be using R22. R22 is banned due to its harmful environmental and health impacts, and it is a sign that your AC unit is old enough to consider a replacement and the significant efficiency gains that could come with it.

You need to service an HVAC system about twice per year, with a service including an inspection and basic maintenance. It’s best to schedule maintenance in the spring (after the furnace has been running and before the AC kicks on) and in the fall (after the AC worked hard all summer and before winter’s first chill arrives). 

Regular HVAC services will keep the system working as efficiently as possible, saving you money on utilities and larger repairs. HVAC maintenance costs around $250 per visit, while bigger repairs from forgotten upkeep could cost thousands.

If you know how to identify supply and return ducts, you’ll find that only the supply ducts will have dampers. Although your return ducts can have dampers, it’s not common. If you have one return duct that is pulling in too much air, adding a damper to it can help with overall system performance. However, dampers on return ducts are not a necessary addition for most homes.

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.

To extend your HVAC system’s lifespan, it’s crucial to keep up with maintenance. This includes changing filters and thermostat batteries, keeping the outside unit clean and clear of clutter, and lubricating moving parts. Watch out for leaks, mold buildup, and blockages to ensure your unit stays in good working order. Spotting these issues early can be the difference between a simple, wallet-friendly repair and an expensive replacement.
