Get matched with top thermostat installers and replacers in Washington, DC

"Avery Savage, the Pro sent by Angi was extremely honoest and very proficient. I already knew what was wrong with my HVAC system so I had already purchased a replacement thermostat. I have known other technicians who have tried to get clients to purchase entirely new systems when only a thermostat was needed. Avery was very honest and excellent job access and fixing the problem. I would use this company again and highly recommend Mr. Savage!"

"This is the fifth or sixth time we have used JW for home improvement projects, and we have never been disappointed. We started with 'simply' trying to find the source of water damage in our lower-level, and ended up renovating our laundry/storage room and installing new vinyl floors throughout the bulk of the downstairs. From Josh making multiple trips out to ensure the estimate and scope was solid, to Marcos and Israel completing the project from start-to-finish, we are thrilled with the results!"

"They replaced three large screens on our deck. He recommended using heavier gauge screen and attaching the screen more securely. The entire job was done professionally, on budget and on time. We were very pleased"

"Spent hours unclogging my kitchen sink and replaced pipes. On time. Nice man."

"The service was provided on the scheduled dates. The work was completed thoroughly; the house and porch look great! All items on the porch and deck were removed and replaced after the work was complete. We would definitely use this company again!"

"I can't believe I haven't left a review after all this time.  Better late than never though.
The movers were great, polite and professional.  The guys were very clear about which expectations they are able to meet and what is realistic with the time frame they are given.  It was a lot of work moving to our new place which was located up 3 flights of stairs but they powered through it!  We provided lots of Gatorade and some snacks as a token of our appreciation!  We ended up paying for additional time but we knew there was a possibility that it would take longer than expected.
We only wish there were no hidden charges for extras like wrapping furniture, etc.  We normally don't have to pay extra for this based on our previous experiences with other movers.  We opted not to avail of those services and they were clear that there was a risk of the furniture getting scratched or damaged.  Fortunately, the furniture was getting replaced with new ones anyway so we didn't care too much about cosmetic damage so long as it stays functional when we reached our new place. However, they did their best to make the least amount of damage to them which was a plus.  
All in all, it was a smooth move and we couldn't be happier about that.

"The audit went well.  The follow-on work (water heater replacement, heat pump replacement, and caulking).
They did a pretty good job.  They did sub out the water heater and heat pump parts.  The new water heater had a heat pump unit on it too.  The water heater had an alarm that went out and was eventually replaced.
The subs did test my patience when they started late and ended even later than they said they would.  I eventually told them they had to get out at a certain time.
I took a year to write this because I wanted to back it up with cost savings info.  Unfortunately, the jury is still out on whether or not the system is paying for itself.

"Now that I'm wobbly on ladders, this vendor comes annually to clear gutters and ensure the attachment pegs are secure before any snow or ice. I've used them for years and will continue to do so. The tech goes above and beyond. Two examples: one year, he replaced a missing shingle; another year, we caulked around an external roof vent. These guys are great."
