"The service was superior from the initial contact where I requested a quote to the installation. I spoke with Samantha to arrange for someone to come out to provide me with a quote and she promptly scheduled an appointment around my schedule. Mike came out and provided me with several options for a heat pump and promptly sent me an email with the heat pump options and prices. I had contacted 4 other HVAC companies in my area that also provided me with estimates. Accu-Rite Services was the only company that followed up to see if I had any questions and to see if I was still in the process of replacing my heat pump. I called Accu-Rite Services a couple times with questions and Samantha was quick to provide an answer and was very knowledgeable. I scheduled a date for my installation and Accu-Rite Services showed up on time for the scheduled appointment. The installation was really quick, old heat pump was removed, new heat pump installed, everything completely cleaned up and new thermostat was installed. Mike gave a thorough explanation of how the heat pump and thermostat worked. Accu-Rite Services took care of registering my heat pump, scheduled county inspection and also checked for any rebates that were available for me. I absolutely love my new heat pump. I highly recommend Accu-Rite Services for all your HVAC needs. Thank you Accu-Rite Services for your superior customer service, honesty, knowledge and for making this a smooth process for me."

"Garrett arrived on time and was attentive to resolving our issues with getting two toilets refurbished/replaced that were damaged by Lowes installation services technicians. He also evaluated the installation of the toilet that was installed. We have not had any work done yet. I will update after we have received the estimates and the projects have been completed."

"We have an old furnace which is working very well and we did not need a repair but we usually have 1 or 2 tuneups every year. Every time we have a technician for tune up he tell us it would be a good idea to get a new furnace. The good part about LLC Heating & Air Condition was that they examine the furnace and thought it was in good shape and did not mention replacement . The visit was short and pleasant."

Install Boiler FAQs, answered by experts

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 average cost to replace or install a new HVAC system is around $7,500. However, the price can range from $5,000 to $12,500, depending on factors like the size of your home, the type and brand of the unit, and your specific heating and cooling needs. If you only need to replace certain components, the cost will be lower; for example, a new AC unit can cost between $2,200 and $5,500, while a new furnace costs $3,200 to $6,000. If additional work like new ductwork is required, the total cost could be as high as $22,000. It's best to contact a local HVAC company for an accurate quote.

To figure out if your boiler is worth repairing or if you need to replace your boiler, first figure out how old the unit is. Boilers last 15 to 20 years, so if your unit is 15 years old or older, it may be better to replace the entire thing depending on the severity of the problems. If it’s not quite that old, then it’s probably worth repairing. Another thing to consider is whether your warranty covers any of the repair costs. If so, it may be worthwhile to repair your boiler to keep it running.

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.

Common problems include leaks, low pressure, and inefficient heating. Regular maintenance prevents many issues.
