"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!"

Energy Efficiency Auditing questions, answered by experts

As you look for the right soundproofing drywall for you, you’ll likely come across the Sound Transmission Class (STC) rating. This rating measures a building material’s ability to absorb sound. The higher the number, the better the material absorbs rather than reflects sound, reducing noise transmission. The STC rating for drywall doesn’t mean it’s for the panel itself—it refers to the STC rating for the entire wall system, including the soundproofing drywall.

STC (Sound Transmission Class) ratings tell you how well something blocks airborne noise. It’s a single number that sums up how much sound a material, like a window, can stop across regular speech frequencies. The higher the number, the better the sound reduction. A typical single-pane window hovers around STC 25 (where you can hear normal conversations), while well-sealed, double-pane options can push past STC 45 (which blocks out loud speech and most music). Just keep in mind that STC doesn’t cover everything—low rumbles like bass or thunder can sneak through—so pairing methods are always ideal for the most peace and quiet.

There are several strategic ways to lower your home insurance premium. The primary one is to shop around and get quotes every few years to make sure you’re getting the best deal. Also, sometimes bundling your auto and homeowner’s insurance will get you a discount on both. Finally, try to keep your credit score up; many homeowner insurance companies use credit scores to generate quotes.

Installing weather stripping or upgrading to insulated panels can improve efficiency.

If you have central air conditioning, it’s fine to run your AC all day if that’s what you want—as long as the AC unit is in good condition. But if your AC runs constantly when you don’t want it to, there may be a problem with your system (like the ones we’ve mentioned above). Window AC units and wall air conditioners aren’t as powerful as central AC, so you should only run those kinds of air conditioners for eight to 12 hours at a time.
