"After 3 weeks of living with no air conditioning, and a leaky ceiling, during which time I had 5 technicians (3 from one company that doesn't even have an option to leave a voicemail after 5pm!) attempt (and fail) to fix the problem, I finally had to get a new system. 



I sincerely hope you don't need to replace your AC system any time soon, but just in case you do, I highly recommend  Alpine Heating and Air.  Their telephone number is: 919-404-1717.  They went above and beyond customer service, and addressed my concerns, explained answers to my questions in detail re: energy efficiency, payment, warranty, etc., and did exactly what they said they would do re: installing on time.  I have a 10 year warranty for parts and labor and a lifetime warranty for the compressor.  If it breaks (the outside unit), they will replace the entire thing.



A week after my system was installed, the unimaginable happened, and my ceiling was leaking again!!!   I couldn't believe it!!!  I called them - this was on a Sunday evening at around 8:00pm - and they told me that they would send someone over right away, and they did.  I told them that this was unacceptable, and that I expected them to replace it w/a new system.  They assured me that they would do that if necessary. Fortunately, the issue wasn't the system, but the pipe in front of it, which the technician replaced.  I was still in shock that my brand new system had leaked, and I asked him to open the panel in front of the system to ensure that everything was OK.  He went back out to his truck and got his tools and it was fine.



The next morning, Alpine called me and apologized for what happened, and offered to have my ceiling fixed.  I was very surprised, and I told them that I wanted to give full disclosure, and that although it had leaked because of the pipe, I told them that I had previous damage from my other AC, but they said it was OK and that they wanted to make things right, so they sent someone to repair it (no charge to me). "

"I bought this service on a Friday and they came on Saturday. They arrived at 10 am and were finished by noon.
I asked them to clean my porch and my sidewalk as well (this was not included in the Deal that I prepurchased) and he did that at no  extra cost.
They were clean, professional, and very good.  I would certainly use them again.

"Excellent service, very fast response to my request for service, picked up laptop, diagnosed issues. Initially thought it was an OS update issue but the hard drive had failed along with other components (including 'CPU). Because other components were involved, a new solid state hard drive was put into a laptop with a working processor - same type CPU as in the failed unit. The laptop was repaired and returned in less than a week. This company picked up and dropped off the laptop (driving from Huntsville, AL (about 60-70 minutes)-- great service in this covid environment. I would recommend this company to my family./friends and will use again."

"Guy that came out said that it was an issue of the boiler not having enough water. He turned the valve to force water to it and and ended making a mess in my basement floor of black gunk water that I had to clean up. Idk if that was necessarily the issue, he said that’s all it was and nothing else needs to be done. He didn’t provide any type of explanation as to why it wasn’t getting enough water when turned on as this is something that should be self regulated, not something I should have to monitor anytime I turn my heat on. I won’t even necessarily know if this is the case and it’s fixed until fall rolls around again and we need heat, as it is now warming up. I hope that he was correct but quite pessimistic, and felt that a more thorough check should of been done."

Boiler Repair FAQs, answered by experts

To maintain a boiler and ensure it works optimally, regularly read the temperature and pressure gauges on the unit to ensure they're within the limits described in your owner's manual. Lubricate the circulating pump according to the manufacturer's instructions. Check the water level in the expansion tank and open the tank valve to drain it if it's more than half full.

Addressing banging, clanging, and hissing radiators involves several steps. Start by bleeding the radiator to release trapped air, a common source of noise. Next, ensure all valves, brackets, and pipes are securely tightened to prevent the components from rattling. You can also consider installing radiator insulation to dampen heat expansion sounds. If you perform all of these fixes and the noise persists, explore the use of radiator additives that can mitigate water-related noises. If all else fails, you should consult an HVAC professional.

Signs of needing a new expansion tank include visible leaks and a dull sound when you knock your knuckles against the tank (working tanks should sound hollow). A malfunctioning tank may also sweat with condensation, cause pipes to create loud noises when the system is turned off, and lead to very high-pressure readings on the boiler’s gauges. When in doubt, call for a professional inspection to find the source of the problem.

Clean regularly, check for leaks, and schedule annual inspections for safety and efficiency.

You can save money on heating oil through a combination of improving home efficiency and smart purchasing strategies.

Home Efficiency and Usage:

  • Improve Insulation: Ensure your home, especially the basement and attic, is well-insulated and sealed against drafts to prevent heat leakage.

  • Manage Your Thermostat: Use a properly calibrated and programmable thermostat. Lower the temperature by a few degrees, particularly when you are away from home or asleep.

Purchasing Strategies:

  • Buy in the Off-Season: Order heating oil during the summer months when prices are generally at their lowest. This strategy is most effective if you have a large primary tank or a separate storage tank to accommodate bulk deliveries.

  • Consider a Delivery Contract: Some companies offer contracts with a set price for the term. This can lead to savings if market prices for oil increase, but you might pay more if prices drop.
