"I needed to replace my parents' 40 year old AC Condenser and coil, and replace it with something that worked with the new furnace my father got installed four years prior. They were able to do the work requested, and also offered to redo the furance installation as the previous company installed it right on the basement floor where any backup/water could possibly get into the system. They were very prompt and showed up on time/on schedule. They were very upfront about costs and pricing and there were no last-minute price changes or hidden fees, which I appreciate. Work was done well and they ensured that everything worked before leaving the job site. The gentlemen working were very professional and understanding. I highly recommend them for anyone looking to replace their HVAC or to correct work that was previously poorly done."

"Highly recommend John with Mayo Plumbing. He was prompt in responding to my initial call, provided an estimate that was much more reasonable than other commercial companies, was able to get me scheduled the next day and did a fabulous job installing a garbage disposal, fixing drain pipes that were a mess and installing a pressure regulator. Thanks for caring to go the extra mile. John is a fabulous plumber!"

Install Boiler questions, answered by experts

An expansion tank must always be installed on the supply side, which is the side where the boiler sends water out to heat the systems. That placement allows the water to push against the air and condense properly as it is heated, then circulated through the system. Professional installers can recommend the best place on the supply side for an expansion tank.

Most experts recommend getting three to five HVAC quotes from licensed, insured, reputable local heating and cooling companies. Getting multiple detailed HVAC quotes (but not too many) lets you compare the equipment, services, and prices of several contractors without being overwhelmed by options. It can also let you see if one contractor’s prices are much higher or lower than the others and give you a chance to ask for clarification. That way, you can weed out any contractors who aren’t providing quality services or materials and find the company that best meets your budget, quality requirements, and long-term goals.

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).

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.

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
