"From start to finish with my project Gary and his team were helpful, responsive, knowledgeable, and professional. Gary considered all of my heating/ac/humidity concerns, took full measurements of my condo, system and energy calculations, and recommended three good options of Bryant electric split heat pump systems. I ended up choosing the most efficient top of the line model as I was replacing a 25+ year old unit. I felt that the price was fair and even if I could have found a slightly lower price, I was very comfortable hiring Pelletier based on Gary’s initial follow-up, professionalism and thoroughness when quoting my job. They also went the extra mile when doing the installation under terrible weather conditions. I’m very pleased with the end result. I have no hesitation in recommending Pelletier."

"After my initial call, representative Pat came to see exactly what we wanted done.  Since we did not know all their options he suggested that the owner Mike come to discuss all the Heating and Air conditioning options for us and the prices.  Mike came and we decided on the mini splits because they were easy to install with only 3 days of disruption to our normal living schedule and they were far less expensive to either hot water heat, which require installing copper pipes in every room and a plumber to do the work and a duct system of delivering forced hot air  to all the rooms with an oil furnace.
We asked that the work start on the 15th of July and it did.  Mike thought it could take three days since the daily temperature was in the 90's but they completed it in two days and left everything clean and orderly.  They did have to cut down some of our foundation plants to make room for the condensers which sit on the ground.
The tubes from the mini splits are run through the walls to the condensers outside and covered with a tube that looks like a gutter drain.  These are on two sides of the house and do look a bit unorthodox on my rough sawn cedar home but I will get use to them or paint them to match the grey stain on the house.  This is why I rated Quality  only good for I have no idea how all these materials rate to other systems and how they will hold up.  Time will tell.
We were able to use them immediately when the installation was completed on the 16th for air conditioning.  Since they work on the same system for heat we only have to change the mode on the remote to Heat and it starts heating the house instead of cooling it.
I had no idea  what a heating and AC installation would cost so I think it is a bit expensive  but I have learned it is far cheaper than other systems especially since my house was built in 1976 with electric baseboard heating which cost a fortune to run in the winter since two upstairs rooms have 18 foot high ceilings.  I have been told this new system will save at least 40 to 50% on electric costs.  I will be keeping track immediately to see if this is true now with the AC system.  If it does I will change my price rating to excellent.

"Not the best, but I guess not the worst either.
They did the door blower test which revealed different air leaks in the house. They sealed around some of the doors in the home, installed some door sweeps, caulked around baseboard registers etc. However, the work was far from consistent and less than professional in quality.
There are 15 registers / returns in the home and we were told they would caulk around them all, they caulked around 7. 2 of which the caulking was so thin that it cracked before the next morning.
There are 3 sinks in the house where pipes were supposedly "foamed and insulated" on their report. There is no additional insulation visible anywhere that I can see.
We are entitle up to 40 CFL light bulbs in the home, however, even the 30 they said they changed were not completed.
For example:
-there are 2 nightstand lamps in the bedroom. One lamp received a CFL and the other wasn't touched.
-there is a hallway ceiling light that was supposed to be changed out with CFLs, but still has the same old bulbs.
-downstairs bathroom still has all three original bulbs
-two bedroom ceiling fans that take regular "A" type bulbs all have the same bulbs
I sent an email to the gentlemen who came out to the house asking if we could at least receive the extra bulbs. He did respond and said yes, but never got back in touch with me. After the general overall experience I did not bother chasing after them for a few more dollars worth of bulbs. However, the whole point is not the money, its the fact that these were all listed on the report and not completed accordingly.
They did recommend an insulation company to come in and give us a quote and also told us about different programs offered from the state which would allow us access to rebates for making home energy improvements. All in all, I guess it helped us to know where the air leaks were in the house, but the overall performance of the team was simply sub-par. They were nice, polite and somewhat informative but by no means "wowed" me.

Over the years, I have had some harrowing experiences when I have faced computer malfunctions.  Just the thought of another telephonic tech support marathon made me cringe.  Until now.  This was the most pleasant computer repair encounter ever.  As I sat comfortably in my recliner, Jim worked his magic on my computer and taught me a few things while he was doing it.  Not only does my middle-aged computer run like a teenager again, I can surf with confidence knowing that he is just a phone call away.  Before you go buy a new computer (as I was about ready to do), call North Alabama Technical Services.  You will be glad you did!

"The workers were very professional. The installation was done during the week thatn we had extremely high temperatures but they showed up every day and worked in the blistering heat of the attic. They also provided a loner window air conditioner for me until the central A/C unit was up and operational. I would highly recommend them."

Install Boiler questions, answered by experts

The absence of heating or hot water, unusual noises like banging or gurgling, and visible water leakage are key signs. Abnormal boiler pressure, flame irregularities (for gas boilers), or pilot light issues may also signal trouble. Frequent cycling, soot or staining, and unusual odors, particularly gas-like smells, should not be ignored. Modern boilers often display error codes or lockout mode upon detecting issues. Uneven heating across radiators and rising energy bills without increased usage can further point to problems. Prompt attention to these signs is essential to prevent further damage and ensure safety.

If you go to turn it counterclockwise and it won’t turn anymore, it’s open. Like most other valves, you should be able to turn a radiator valve counterclockwise (to the left) to open it and clockwise (right) to close it. To close a radiator valve, turn it clockwise until you meet some resistance and can’t turn anymore, but do so carefully to avoid breaking the valve.

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.

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

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