"It went great. Brian's team came the first day and took their time looking at everything I needed done. When the saw I was missing some components for the microwave installation, they took it upon themselves to go out and find the right components for me so I didn't need to worry about it. They came back promptly the next morning, and were able to install my microwave. and it looks GREAT!! They then helped me install a new light fixture while also repairing several other lights around the house. Many contractors can do this stuff. But what set Brian and B.C.G. Building Solutions apart was his wilingness to explain all the tools and techniques to me in ways I could understand. He was patient and peristent when faced with some wiring issues in my old house, and best of all, he and his team have a great sense of humor! I'd definitely recommend B.C.G. Building Solutions to anyone and I am eager to continue working with them in the future."

"I hired K & K to install a range hood. There was no electrical there previously so they had to run electric. I also had them install a new light fixture and remove an exhaust fan. K & K did excellent work and even repaired an electrical box that another contractor had installed. I was given a great estimate and was charged the estimate price. Would definitely use again and recommend."

"I called ABC Heating and Cooling when I found my air conditioner leaking out the bottom. since my unit was getting old I opted to have it replaced. ABC beat other prices by almost 50% and were ab!e to get my new system installed within 4 days. I am extremely pleased with how knowledgeable and how responsive everyone was, whether I called Mike with questions or was talking with his technicians. I will definitely recommend ABC Heating and Cooling to anyone needing work on their air conditioner!"

FAQs for thermostat installation and replacement projects in Perry Hall, MD

Smart thermostats may be worth it for many homeowners. They come with various features, including voice control and smartphone apps. Vacation mode can help lower energy usage when you’re out of town for an extended period. Alert warnings let you know about major spikes or drops in temperature. Smartphone apps can track energy usage, and smart thermostats can learn your routine over time to adjust your temperature and reduce wasted energy consumption automatically.

You typically do not need more than one smart thermostat. While it’s common to see multiple mechanical thermostats throughout a large home, multiple smart thermostats may try to override each other. This can lead to problems with the HVAC system. Ensure the unit you buy has the option for dual- or multi-zoned systems to avoid compatibility issues.

Installing a programmable or smart thermostat may save you $180 per year in utility costs. A big part of this comes from a smart thermostat’s ability to learn and adapt to your regular routines. With smartphone apps or web-based interfaces, you also have the option to control your thermostat when you’re not home.
