"Shawn was a professional from start to finish. He was transparent about his pricing, communicated clearly, and finished the work in a timely manner. My heat pumps efficiently heat and cool my house, and I recently contacted him to install another in my work office. I would highly recommend Shawn for all your heating, cooling, and maintenance needs."

"Tim Baker, owner of BKR was very responsive when we were seeking a professional to replace our water heater in an emergency. His price was very competitive. We were absent and he dealt professionally and courteously we our condo staff. His work was neat and our water heater is working well. He also promptly provided detailed estimates for insurance needs. Highly recommend this company"

"Susannah is a GEM! We love her and will never hire anyone else to clean our house. She has great attention to detail and goes above and beyond. After she leaves, we just point out things she did such as “She cleaned my mouse pad!” or “She cleaned the toaster oven!” And praise her work. She is professional, reliable, and does such a good job. She is worth every single penny and more. We are so lucky to have her!!"

"Did a great job on our steam boiler. Came in way under the estimate because he found the parts just needed to be cleaned instead of replacing. Very honest and reliable. We will have him back for regular maintenance. I highly recommend Kyle. Thanks for the great job!"

My name is Jay Scannell and I enjoy cleaning and making things spotless. My mother always made sure our house was clean as I was growing up and naturally I have liked to follow those similar footsteps and take it that one step further. I’d enjoy cleaning for you and your family if need be and I am open to anything you throw at me:).

"Mr. Ferrell first connected his computer to my computer via internet and worked for quite a few hours trying to determine what exactly was wrong. The next day he continued working from his computer for several hours. He determined he would have to have my desktop tower to complete the repair. He and my son met in Huntsville to exchange the tower. He then cleaned up a lot of what was wrong and reloaded Windows 10. He deleted the D: drive which had way too much memory allotted to it. The tower was returned and I plugged it all back together and it is working better than it did when I first purchased it. I would use him again and I recommend him highly to anyone needing computer updating and/or repair. His work is warrantied and he is very personable, knowledgeable, and helpful."

Heating and Air Conditioning FAQs, answered by experts

A new HVAC system combines components to control indoor temperature and air quality. Features include a furnace or heat pump and an air conditioner or evaporator coil, depending on the climate requirements. It also involves a network of ductwork for air distribution, a thermostat for temperature regulation, and electrical connections. Air purifiers or humidifiers can be integrated to improve indoor air quality.

Air filters with a high MERV rating, 11 or above, shouldn't cause airflow problems in most residential systems. However, the airflow can be restricted in some HVAC systems if they aren't designed for high MERV ratings. If in doubt, a local duct installer should inspect your ductwork so that you know what your system can handle.

Because of the improved efficiency, ACs with higher SEER ratings tend to cool down your home better than models with a lower SEER. Higher-SEER AC units have a higher cooling capacity and a lower energy demand, meaning they may help cool your space faster without running up the electricity bill.

There are two main reasons your furnace and AC are turning on at the same time. The first could be that you’re confusing the furnace with the blower. The blower is located in the furnace and will turn on to distribute cool air from the air conditioner through the ductwork in the home. This is normal. If the actual furnace is turning on at the same time as the AC and hot and cool air are coming into the home, it could be a result of incorrect writing to a new thermostat or new systems.

It’s critical to use the right size AC for your space and not go too small or too big. If you purchase an undersized unit, it won’t properly cool your house, and it has to work harder to reach the optimal temperature. This will eventually wear your unit out. An oversized unit can spell trouble because it will turn off and on more frequently, which also wears out your AC unit. An oversized unit also causes humidity in the home.
