"Extremely customer service experience. The representative I dealt with was not only unhelpful but also came across. As both judgmental and lacking professionalism when I asked clear questions about pricing I received vague misleading answers. They scheduled an appointment that I had agreed upon for one o'clock pm but no one show up or call. Instead I received a text for 1 o'clock pm.; When I called to let them know The situation and the pricing they have changed their answer from 1 -3pm and told me that there was a fee that would be applied. When I asked a follow up question the Rep. hung up on me. The overall behavior was unprofessional and extremely biased based on demographic that they choose not to served. I would expect more transparency, respect and communication."

Our Service Plumbing team is ready and willing to tackle your project - be the need immediate or not. Simply reach out and we will dispatch a technician immediately to provide a quote and solve your problem!

"Only rating 1 because it doesn't go lower. Had a new unit installed end of Sept 24. First time power goes out on 11/5, no electricity. When tri state sells you a product, they pitch their amazing customer service with all these guarnatees of knowing when your unit is out before you know and having someone there within 24 hours etc. Well, the first call we make we are told it will be the end of Nov to get someone out to look at it. 3 weeks. Nobody shows up. Then we get a call that says "your appointment on Dec 12 has been canceled and the earliest we can get to you is Jan 16th. This is 2.5 months wait to get service to fix a nearly $20k unit, that is upcharged because of the excellent service. You can't get anyone to answer your call. you wait on hold for 20 minutes, then have to leave a voicemail in which you will not get called back. Based on my experience, find someone else and pay less. Even if the service is bad, which it can't be worse than this, you save money! @kohler"

Install Boiler questions, answered by experts

Installation costs range from $4,000 to $12,000, depending on unit size, efficiency rating, and labor.

Boilers are equipped with multiple safety features to ensure safe operation. These include pressure relief valves to prevent overpressure, temperature high-limit switches to avoid overheating, and flame failure safety devices in gas boilers to cut off the gas supply if the flame goes out unexpectedly. Low water cutoffs prevent operation with insufficient water levels, and pressure gauges help monitor pressure levels. Ventilation and flue systems prevent the buildup of harmful gasses. Boilers often feature error code systems for automatic shutdown during malfunctions and gas leak detection for safety. Regular maintenance is crucial to ensure these safety features function correctly.

The absence of heating or hot water, unusual noises like banging or gurgling, and visible water leakage are key signs. Abnormal boiler pressure, flame irregularities (for gas boilers), or pilot light issues may also signal trouble. Frequent cycling, soot or staining, and unusual odors, particularly gas-like smells, should not be ignored. Modern boilers often display error codes or lockout mode upon detecting issues. Uneven heating across radiators and rising energy bills without increased usage can further point to problems. Prompt attention to these signs is essential to prevent further damage and ensure safety.

It can take anywhere from four hours to three days to replace a boiler with a new one. How long your particular boiler installation takes will depend on whether you need a gas line installed and if you’re switching to a new boiler system. 

Replacing a combination boiler or standard boiler with the same system should only take four to six hours. Meanwhile, switching from a conventional boiler system to a combination boiler system could take a few days.

HVAC systems last between 10 and 30 years, with an average life span of 20 years. However, the components of an HVAC system have different life expectancies. For example, a heat pump lasts between 10 and 20 years on average, while a furnace might last between 15 and 30 years.
