"Pressure tank for my well ruptured. Appleton Campbell literally responded in a minute or 2, and within 2 hours someone came out to give me a quote and said that this could be fixed by 2 pm. I hired them and sure enough everything was done very quickly and I had water again! Price was a little higher than I expected but it was definitely worth it due to the professionalism of the crew they sent to do the work. I would definitely hire Appleton Campbell again!"

"After an initial inspection, I was provided with two options for the repair. Both options were acceptable fixes for the damaged wood. The suggestions were to either replace the post, or remove the damaged bottom and install a cement base to support the deck. There was about $100 difference in the cost between the two options. It was nice to have a cheaper alternative that I had not even considered. Work was completed and looked great."

"“I strongly recommend JW Home Improvement for all home repair and renovation needs. Over the past few weeks we have had various projects completed, including, exhaust fan installation, stairwell repair, dry wall repair, exterior dormer and trim replacement and gutter/downspout painting. All of the technicians were friendly, prompt, knowledgeable, respectful, highly skilled and operated efficiently to finish ahead of scheduled time. Pedro, Kevin and Antonio in particular were exceptional in going above and beyond to produce truly beautiful work. The craftsmanship and precision displayed by these technicians was extraordinary and they were an absolute pleasure to have in my home.”"

"Great. Mike and I talked briefly through Angie's List messaging system, I described what I needed, he quoted an hourly rate along with estimate of time needed, we set up a time and were good to go. Showed up on time, I explained what I needed done showing him each item and he got to work. Kitchen faucet: I thought it was just a bad washer or o-ring, but it turned out to be a plastic part (that interacted with a metal part) that had worn out deep inside the faucet, which he found by disassembling the faucet. Showed me where it was and what it did, and unfortunately there was no replacement part available. Also explained that he had seen black/rusty water when he was taking things apart and the valve/lines under the sink needed replacing too. (This explained some odd tastes we were getting from the sink water.) He asked me what type of faucet and quality level I wanted (cheapest, most expensive, middle), went out and bought it plus the other needed parts, returned and installed it all. Works great and the water doesn't taste odd anymore. What I thought was a simple job turned out to be more complex and longer. Bathroom sink faucets: Fairly straight forward replacement, though he did have to shorten the connecting rod connecting the drain plug to the post you pull to close the drain. There isn't much space under the cabinets! Also pointed out a small leak in the pipes underneath, which he fixed as well. And he cleaned out all the build up in one of the drains so it drains promptly now. Toilet: Replaced the clogged valve in a jiffy along with the feed line and the tank hardware, and now, instead of taking 20 minutes to refill, it refills in a short time, stops when it's suppose to stop, and doesn't leak. Bathroom: Removed the towel rack, moved and leveled the shelf. And, he tightened the nut holding the toilet seat cover onto the toilet without even being asked, just because he noticed it. (We had lived with it after my attempts to tighten it hadn't worked.) Kitchen cabinet: Removed the drawer and pointed out that the wheel rails can spread at the back, from use. Closed the spread and now the drawer slides in and out perfectly. (I felt dumb for not having figured that out, but now I know.) Cleanliness: He had canvas drop cloths to catch any dirt or grime he generated as well as for protecting the floor. Had a trash bag for any trash generated (such as the faucet boxes) and used it as he went, rather than gathering the trash at the end. Honesty: Even though he ended up doing several extra things (valves and lines under kitchen sink, fixed a leak under bathroom sinks, toilet seat cover nut), I did not get the vibe that he was finding these just to do them and earn more money. The kitchen faucet issue agreed with what we had already observed, and the leak in the bathroom sink cabinet was real and (obviously!) needed fixing. And the seat cover nut, well, that was just a nice touch. All in all, I am very pleased with the results. Very pleased with his attitude and willingness to dig in to get the job done and working until it was. He explained the extra work needed as he found it, and didn't bother me unduly (I had my own work to do, as well, working remotely that day). And when I stepped over to see how it was going, he gave a precise update. He had all the tools needed (most of which I don't have, such as plumber's putty), and he had several spare parts in his truck so he wasn't constantly driving over to Home Depot. In short, he came prepared. Turned out to be 8 hours of work instead of the original estimate of 5 or less. Charged by the hour, and for the faucet and valve and bit of pipe installed (about $200 in parts). I like that flexibility, rather than charging a flat rate for a block of time (4 hours or 8 hours is what I've seen elsewhere on Angie's List site). The rate was competitive and I tipped him as well. The amount indicated in this review is for parts and labor only."

"We had an absolutely fantastic experience with X&M Heating and Cooling! From start to finish, Richard was beyond responsive, professional, and genuinely a pleasure to work with. You don’t always expect replacing major home systems to feel stress-free, but Richard made the whole process smooth and even enjoyable. They replaced our AC/Furnace (Condenser, Coil Pack, and Heater) as well as our hot water tank—a big job—and the crew knocked it out of the park. Everything was installed with care, attention to detail, and a clear pride in their workmanship. Richard took the time to explain what was happening every step of the way, which gave us total peace of mind. What stood out most, though, was the responsiveness. Whenever I had a question, Richard was quick to answer, patient, and genuinely friendly—it felt like working with a trusted neighbor rather than just a contractor. If you’re looking for a team that does top-notch work - don't look any further."

FAQs for thermostat installation and replacement projects in Fairfax, VA

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.
