"John Wiltshire was able to fit us in on this super hot day. Wasn't expecting his service until tomorrow. I'm so thankful he found the problem and it didn't cost an arm and a leg. Excellent work, very polite and explained what needed to be done. In no time we had AC again. I would highly recommend. Thank you, Spoor's Heating &Air ?"

"Service plumber arrived on site, on time and was ready to begin. He was friendly and professional. He was fully aware of the problem and what needed to be done. He acquired the necessary parts and changed them accordingly as proficient as possible. Our bathroom sink drain issue was completely resolved and ready. Thank you Eric for a great job!"

"I would like to start by saying that the service I received from Kermit at Chapman's Legacy Plumbing is the exact reason I am a member of Angie's List! Kermit was a true professional who was able to trouble shoot all issues with my sink and water in the kitchen. He corrected several issues and located all necessary parts to avoid replacing major parts like the entire faucet. Kermit was punctual, explained everything he was doing or needed to do, performed quality work and was just an all around friendly person. After reading a dozen companies reviews and taking a chance, I got exactly what I was hoping for. THIS IS WHAT MAKES ANGIES WORTH IT!! Thank you Kermit!"

"I got say, these folks (Bell Bros.) really did go above and beyond..... for that, I am most grateful and appreciative. My dad isn't exactly the most proactive person, so when his A/C unit started making an unusual sound, I decided to do something about it. I called the Bell Bros. and scheduled an appointment to have their $87 tune-up done on his system. But upon arrival, technician Anthony, immediately recognized that is was a more serious problem than we thought. But what caught my attention was more than the usual quote. They REALLY are the "No Surprise Guys". Anthony took the time to explain the situation. Not only detailing the matter at hand, but also providing insight on possible future repairs. Even to be so honest as to provide information on the plausibility of having to replace the system, which no one wants to hear. But, nevertheless, he was honest and ground, which always goes a long way with my family. I am more than content with the service provided by Anthony and Bell Bros. and will always go to them to seek their advise on these matters. I cannot express enough my gratitude for their assistance. I usually do not take time to write reviews, but for these folks I am."

"The team of four was very professional and performed an excellent job in a record period of time. Just one day to take the old furnace away, replace all the old boots and duct work and install the new furnace. They paid a lot of attention not to damage or dirty the floor/carpet. I am very happy with their performance. They may not be the cheapest on the block but it was all worthed and you only have to do that once in your lifetime."

"When it became clear that my existing HVAC system needed to be replaced, I initallycontacted thecompany that was the original maintenance contractor.  They made a proposal for system replacement, but, would not give me a paper contract explaining the complete work to be provided.  Indeed, said contractor proceeded to try to sell me additional items I did not want or need.
I subsequently called Diamond for an estimate.  Bob came to the house and thoroughly explained various options and provided
written contracts for the alternate proposals.  The straight talk approach was really appreciated (especially after the snake oil salesman from the prior vendor).  After a day's review, I authorized Diamond to proceed with the installation.
The Diamond staff showed up on time and finished the installation by the end of the second day.  They were extremely professional and patiently explained what was happening at each stage of the project.  Behing the professional staff, Bob an Elaine Weatherford remained in contact to make sure that I was happy with the work.
My only concern after the project was completed was the interaction between the new system and the smart vent system.  Bob and his staff made sure the my concerns were resolved.
I unconditionally recommend Diamond HVAC sysems to anyone who wants to depend on dealing with honest, no nonsense, business professionals.

Boiler Repair FAQs, answered by experts

A furnace is a big unit where gas, heating oil, or electricity heats the air. The warmed air is then pushed back out through ducts and vents. 

A boiler uses electricity, heating oil, or gas to heat water that is pushed into the room through a radiator. This is one of the oldest and most effective ways to heat a house, but radiators can also be unsightly and leave hot and cold spots in the room.

Heat pumps use a refrigerant to move heat from outside into the house and return it to the room through ducts and vents.

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

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

There are many signs and symptoms to look out for that can indicate that your HVAC system needs repair, including the following:

  • Your indoor air is uncomfortably hot or cold.

  • Your energy bills suddenly increase without explanation.

  • Your AC is blowing warm air or not blowing air at all.

  • You notice leaks around your HVAC equipment.

  • Your equipment makes unusual noises during operation.

  • You notice strange odors coming from your equipment.

  • You notice that the humidity in your home is higher than normal.

  • The thermostat no longer seems to match the actual temperature.

The average cost for HVAC repairs is approximately $350. However, prices can range from as low as $100 to as high as $3,000 or more, depending on the type of repair and the extent of the damage. For example, a relatively inexpensive capacitor replacement may cost $100 to $500, while a major compressor repair can range from $750 to $2,000. Other common repairs and their typical costs include:

  • Blower motor repair: $200–$500

  • Circuit board repairs: $100–$600

  • Evaporator or condenser coil repair: $400–$1,500

  • Heat exchanger repair: $100–$200

  • Thermostat repair: $175
