"I have an old pressure relief valve replaced today. the service person was great, and the installation went really well. My main complain was the price after I did an online comparison. usually, the PRV installation will cost around $500 on the high end, but Bell Brother charged me $1600 since the new valve does not fit the old pipe, and they needed to redo the pipe. My family has been using bell brother for many years, we trusted their workmanship, but the markup is just too steep to justify. I definitely learned my lesson, for small jobs, will use home-advisor instead."

"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.

"This was a two day job. The two men, Willie and Jose, who did the work were competent, courteous, and professional. They were responsive to our questions, did a good job of tidying up, and worked diligently. I think the work went very well. Installation was completed yesterday, and so far everything seems to be fine. Willie and Jose were knowledgeable about what had to be done and understood our concerns. We have no complaints at all, and would recommend them to friends and family who need HVAC work done."

"I highly recommend A/C Girl to anyone that needs help with their air conditioning or heating needs.  They are very reasonable, accommodating and pleasant to work with. 
Our water heater rusted out and needed to be replaced.  The A/C unit for our house runs parallel to the water heater and the pipes from the A/C unit blocked access our water heater.  The water heater repair company requested that the A/C pipes be moved so they could replace it.  A/C Girl came out, moved the pipes and the water heater was changed.  I called A/C girl back and they promptly replaced the A/C pipes and gave our unit a tune up.
 
They were willing to work with our schedule to perform the needed work.  We kept changing dates on them due to problems encountered with our water heater installation.

Install Boiler FAQs, answered by experts

Most propane boilers last 15 to 20 years with regular maintenance and proper care. The lifespan depends on the quality of the unit, proper installation, and the level of maintenance. Investing in annual service can maximize longevity and efficiency. Routine inspections and timely repairs prevent early breakdown, ensuring your boiler heats your home for years to come.

While you’ll pay more upfront for a brand-new HVAC unit, you can save money in the long run. Here’s how to save on your new HVAC system:

  • When purchasing a high-efficiency system, your energy bills will be lower in the future.

  • You may be eligible for special offers from your local energy company.

  • Depending on the system, you may be eligible for HVAC rebates and tax credits.

  • Choose to replace your air conditioning unit and furnace simultaneously to save on labor and installation costs. 

You can replace baseboard heaters with many other types of HVAC systems, including forced-air furnaces, hydronic heating, and heat pumps. Each one has its advantages and disadvantages, so the best choice for you will depend on your budget, preferences, and the design of your house. If you aren’t sure which option is right for you, ask an HVAC pro for guidance.

All modern boilers are condensing boilers because they’re the most efficient type. Instead of extra heat leaving through the flue, these boilers trap the heat and use it to heat the house. Whether you choose a combi boiler, system boiler, or regular boiler, you can opt to get a condensing system. If you have an old boiler that’s not a condensing boiler, it’s a good idea to get an upgrade.

If you have a closed-system boiler that requires an expansion tank, you cannot safely operate it without one, as this risks extensive damage or even explosions. You must find a way to make room for the installation. Options include repositioning the boiler, rerouting the boiler piping to a more open area, or performing minor remodeling to create the necessary space. If you are unsure whether your boiler needs an expansion tank or how to best accommodate one, it's recommended to have a local heating service professional assess the situation. They can confirm the requirement and suggest the most practical solution.
