"Jason and Alex were on time and the job went well. Completed in approximately 5 hours. Jason explained why some equipment differed from the contract (provided part fit better into existing duct work). Jason noted that the internal components were the same. My wife and I purchased a mid priced unit. The price below reflects an approximate cost. The sales representative (Randy) wanted us to decide relatively quickly noting that now was a slower time for their crews. Working with Scott, Randy adjusted the quote. We had already received one other quote (liked the rep there) so we knew the Rescue Rooter proposal was competitive (even if we did not get truly a break). Our existing system was failing so we wanted to move forward. Jason and Alex explained what needed to be done to maintain the system and how to work the new thermostat. We purchased through Home Depot."

"Everything turned out well in the end. They had a few problems on the way but they fixed them. We’ve had them out for different things like the furnace, air conditioning and things like that. The main problem this time was, it wasn’t the same person that came out each time. One person made a mistake and then someone else had to come out and fix it. The person who made the mistake should have noticed they were doing something wrong. I don’t know if they were less experienced or if they didn’t pay attention or what it was. When we called and said there was a problem, they did get it corrected. They sent out somebody I guess with more experience and he took care of it. Overall I’m happy and would use them again. They did our furnace several years ago. I haven’t called or compared their prices to anyone. I have talked to friends who have had similar things done and they said the price is probably about right. It wasn’t a very professional way to did it though. I would use their services again in the future."

"There was only one hang up. When I contacted them through e-mail I indicated that I wanted to talk about installing an antique wood burning stove in addition to the chimney inspection and cleaning. The appointment was made for the afternoon on a certain day. But, the guys called that morning and left a message on my voicemail saying they could come early. I did not get the voicemail and they showed up early anyway. I was not home but my mother was there. Unfortunately, these guys did not get the word from the scheduler in the office that I wanted to talk about the installation of the wood burning stove in addition to having the chimney cleaned. So they came did they work and left. I called the workers back (since I had their phone number from the voicemail) and communicated my annoyance at the schedule change. The guy was very apologetic and offered to come back though he was no longer available at the scheduled time which I had blocked off on my calendar.
However, we ended up talking about the project over the phone and he was able to give me all the information I needed about the potential installation over the phone. He was very knowledgable and helpful. So, I'd like to give them a "B" for punctuality though that doesn't seem to really fit the situation. So they get all As despite this little hitch.

"HVAC EVOLUTIONS services technician Mynor Morales was very promt and friendly in his services. He arrived within the hour I had contacted his company when my furnace suddenly stopped working the day before a very large storm was to hit our area.  After finding the problem he was able to get the part and install it without delay. I found him to not only be helpful and fair but honest, which is pleasantly surprising  sometimes in this industry especially when you are faced with  a sudden emergency. Instead of calling the big names I took my friends recommendation and called HVAC EVOLUTION Home Appliance Repair Heating and Cooling Services.  I was very glad I did and will certainly not only pass the referral on but I will also feel good about calling them in the future.

Install Boiler FAQs, answered by experts

If you hear your radiator clanking even when it’s turned off, it’s typically because there’s trapped water or air in the system, causing a pressure buildup. When you hear significant clanking, popping, crackling, or banging in a radiator that’s turned off, you’ll want to bleed the pipes or call in an HVAC specialist to deal with the problem (and prevent it from happening in the future).

To figure out if your boiler is worth repairing or if you need to replace your boiler, first figure out how old the unit is. Boilers last 15 to 20 years, so if your unit is 15 years old or older, it may be better to replace the entire thing depending on the severity of the problems. If it’s not quite that old, then it’s probably worth repairing. Another thing to consider is whether your warranty covers any of the repair costs. If so, it may be worthwhile to repair your boiler to keep it running.

No, there isn’t always water in radiators. In a one-pipe system, water is constantly circulating from the boiler to the radiators and back. In a two-pipe system, water travels through two separate channels: one that goes to your radiators and one that returns back to the boiler so it can heat up again.

Coolant and antifreeze are technically not the same thing. The difference between the two is the ratio of water to other chemicals. True antifreeze is mainly made up of either ethylene glycol or propylene glycol, while coolant comprises one part antifreeze and one part water. However, the terms coolant and antifreeze are often used interchangeably, even by pros.

Warmed or cooled air can escape your home through drafty windows and doors. If you notice any gaps, be sure to caulk and seal them. You can also hire a local pro for an energy audit to get a list of energy-saving recommendations. 

Finally, check your insulation. It can settle in over time and become less effective. The Environmental Protection Agency (EPA) estimates that you can save an average of 15% on heating and cooling costs (or 11% of total energy costs) by sealing leaks and making sure attics, crawl spaces, and basements have a nice layer of insulation.
