I have been in the construction industry for over 25 years. As a homeowner needing to get things done that I do not have time to do, I tried to hire people to do the work for me. If I contacted companies, they did not answer the phone and if you left a message they did not call back. If they did call back or they would schedule appointments and never show up or if they did show up you would never hear from them again. If I was lucky to find one that provided an estimate, they did not know how to do the projects requested. Larger companies do not want to do the "little" things. At the point of getting so frustrated, I decided to start this business so that other homeowners would not have to go through this. I have hired professional and qualified people; drug test and background checks have been performed on them to ensure clients safety. The technician comes out, accesses the work and pricing is given on site. If pricing is accepted, the technician will perform the work immediately. You do not pay for the work until the job has been completed to your satisfaction.

"Customer service was superb and concise. The information about what was to be done was excellent. The handyman was experienced and completed the job in a timely manner!"

Handyman with over 10 years of experience working on residential homes. My services include but are not limited to : Paint, Drywall, Carpentry, Plumbing, Electrical and Tile.

"I highly recommend Julio. He re-stained and re-sealed my wood front door. This took multiple trips to my house to put on mulitple coats and he showed up everytime, also keeping in touch about precise estimated time of arrival. He also did excellent work, with attention to detail and ensuring that he didn't damage anything else in the process. Very nice to work with and professional. Will hire again. Before and after photos attached. Any unevenness in the stain is due to nature of the wood itself; he balanced out the absorption of stain very well compared to the original stain on the door."

"Review for Service 1st Pros Heating and Air Conditioning In my hectic and fast-paced life I want to take a few minutes out of my day to share our experience we’ve recently had with Service 1st Pros Heating and Air Conditioning. I want to ensure that I include each of the individuals who demonstrated a level of customer service that was exemplary and professional in every aspect of getting our air conditioner repaired. It is not often in our current economy that we find this kind of customer service from every employee in the business that we interacted with. Our heat pump unit went out on June 30, 2023. When I mean out, that left our home at a steady 86 degrees for eight days. It was unbearable and the Technician who was authorized by our Home Owner’s Warranty company to look at our air conditioning issue stated that the problem was in a freon line going into the external wall and he was not comfortable repairing it. WoW…! My husband searched for and got quotes from several different companies very quickly on line and based upon the number of outstanding reviews, we chose to move forward with Service 1st Pros Heating and Air Conditioning after speaking with the front office personnel, Emma and Lindsay who redirected his call to the appropriate person. Technician Chuck Norris was dispatched to our home on Saturday, July 8, 2023, and verified that the problem was in the freon line and was confident that it could be fixed, but it was later in the day and technicians don’t carry every bit of equipment necessary to fulfill each unique job. He did call into the front office and spoke with Tina to establish a quote. My husband was with him as they spoke in a way that demonstrated her knowledge of these types of jobs, what it required, and how to best get it done quickly. Tina once again demonstrated a sincere concern and commitment to help us get the job done as soon as possible. At the end of the call, my husband had a date of the following Monday, July 10, 2023 for a technician to complete the job. On Monday, Karl Davis arrived promptly as he stated in his text and began the task of repairing the freon line that included welding and fixtures on the external siding. He was very knowledgeable, confident in what he was doing, concerned about the temperature we were living in, but fully committed to getting the job done correctly the first time he did it! After several hours, he came upstairs and looked at the internal air handler and safety switch to ensure that they were all working correctly. Again, this thorough and pro-active approach to repairing our heat pump is not the level of service we experience. Technicians come to fix one thing and don’t look at other indicators of what potential problems could impact the long-term repair of an appliance. We couldn’t be more pleased with our selection of this company as our provider for our air conditioning repair. Every single person we interacted with knew their job well and had an understanding of the bigger picture, thus working together very effectively. We don’t anticipate the need for their service any time soon, but would definitely recommend Service 1st Pros to any of our friends or neighbors!! This company guarantees WOW service and we received that and more!"

FAQs for thermostat installation and replacement projects in Cumming, GA

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.
