"The service technician Victor arrived on time and politely introduced himself. Prior to commencing work he inspected the work area (installation and clearances etc). He explained the house heating would be off as he cleaned filters etc. After cleaning/adjustment/testing was conducted, he went over the test results printout with me. All good and nothing required further work."

"Jarod installed a new high efficiency boiler and extensively re-plumbed our central heating system about 12 years ago. He is quite knowledgeable and explained clearly the work he would be doing. The project was completed in a timely manner to our complete satisfaction. I highly recommend him."

"I called to make on appointment for an estimate to replace our 30 year old boiler. The appointment was on my day off a few days later. Mike showed up on time. He inspected the boiler and the house, asked questions about the house and what I wanted. Gave me advice on what I wanted to do. Mike e-mailed me three quotes a few day later, with specs on the boilers. Called me a few days after that to see if I had questions. I made the appointment for the install, again, on my schedule. Mike and his crew showed up on time. We went over what was expected, and his crew was off the the races. They removed the old boiler and installed the new boiler as promised. Mike and his crew were very professional at all times. Highly recommend Ethical Home pro."

"Sunrise Heating and Cooling did an excellent job installing my new Rinnai tankless water heater/boiler. From start to finish, the experience was smooth and professional. The crew was knowledgeable, punctual, and took the time to explain the system and answer all of my questions. The installation was clean, efficient, and clearly done with attention to detail. Everything works perfectly, and I couldn?t be happier with the upgrade. It?s clear they take pride in their work. If you?re looking for reliable, honest, and high-quality service, I highly recommend Sunrise Heating and Cooling."

Install Boiler questions, answered by experts

Using heating oil to heat your home has its advantages, but it also has its disadvantages. 

Consider these drawbacks before installing a heating oil system:

  • Heating oil prices fluctuate frequently

  • Risk of oil spills or leaks

  • Produces more air pollution and soot compared to a gas furnace

  • Regular maintenance required for equipment

  • Need to reorder heating oil consistently to avoid running out

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.

Safety concerns with propane boilers include proper venting to prevent carbon monoxide buildup, secure gas line connections, and regular inspection of safety controls. Professional boiler installation and annual maintenance are essential to minimize risks. Having a carbon monoxide detector installed in your home is essential for early detection of any leaks or ventilation issues.

Professional HVAC installation requires licensed expertise in several areas, including electrical- and plumbing-related work. An HVAC team must know how to safely handle regulated refrigerant chemicals and the gas, oil, or propane used in furnaces and boilers. A proper HVAC installation protects your home from energy loss, fires, and even carbon monoxide leaks.

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.
