"I had Green City Heating come out to repair a leak on the exhaust vent of our furnace which had allowed water into the furnace which caused some rust. Murphy was very responsive with a quick look at some photos I sent, and sent a technician out to repair the leak. Tyler came out and fixed the issues quickly, professionally and under warranty. He was super patient with questions and gave clear explanations of the problem, the fix, and things to look out for in the future. I will absolutely use Green City Heating for future work on our furnace."

"Of the eight companies who bid, Greenwood did the best assessment of the somewhat quirky situation my old house presented. The estimator came just a few days before the big freeze in January, and they were able to schedule installation within two days. Once the installers were on site, there was some confusion re where various components would go, but a phone call to the company cleared that up within an hour. From then on the heat pump installation went smoothly and professionally, the electricians did a quick and effective job of hooking it up to the service, and the site was left clean. I did not understand at first how to operate the thermostat, given that the Mitsubishi owners manual was of limited help, and per my request a rep from the company came out a few days later to give me a tutorial about what the range of settings can do. From then on the system has operated flawlessly and lives up to its reputation."

"I won't call any other heating or AC experts ever again. Twice now, I've had incomparable experiences. I had another highly reputed company come diagnose my failed furnace and provide an estimate, but AirPros' price for the same part and repair was much more reasonable and furnace repairs are not cheap, so the difference mattered significantly. AirPros also treated me like family. Go with this family business, you will be happy."

"Darrick came out when no one else could and went through my Furnace and Air conditioner. The furnace was fine but found a potential problem with the air conditioner and went out of his way to get the part and fix it right away. I am now looking at having them install a new Thermostat for me. I Highly recommend them and would use them for all my needs."

"John provided great service and got the job done! For sure, I would hire again. However, I rated a B because the total cost was not 1) what I was quoted and 2) was given to me after the service was done. This would not have changed the outcome (I would have said yes do it) but customers should be informed of what the cost will be before anything is fixed."

Boiler Repair questions, answered by experts

Unless they are connected to the same system, boilers and water heaters will both need their own expansion tanks. The only case they wouldn’t have separate expansion tanks is if the boiler is pulling double duty and managing a heating system while also supplying hot water for a home. In which case, you may not need a hot water heater.

Always consult your manual for specific pressure numbers. Many expansion tanks come pre-pressurized at a specific PSI range, anywhere from 12 to 40 PSI, designed for a range of home boilers. You should not have to pressurize an expansion tank yourself, only the boiler system. If your system has a tank that needs to be manually pressurized, this is generally a job for professionals and their tools.

If your boiler is 20 years old, it’s time to get a new one. Although it may seem to be working fine, it’s likely eating up more fuel than it should. Also, compared to a brand-new boiler, one that’s 20 years old is probably not working as well. When you get your new unit, you’ll notice that your home is heating more quickly, and the heat is consistent throughout all the rooms.

The most important sign of a boiler problem is something happening unexpectedly, which is why regular boiler maintenance is important. Unexpected problems can include strange smells, new leaks, and unexpected noises that your boiler wasn’t making before. Additionally, if a boiler keeps shutting off or can’t maintain a specific temperature range, it’s time to call in an expert.

Most repairs take 2-6 hours, but extensive repairs or part replacements may require a full day or more, depending on availability.
