"very impressed----joe the estimator was very knowledgeable and not pushy-----gary the installer was super and very careful to clean up every little bit of dirt---mike who did the furnace tune was super ------------how often do you have a company so honest that when you ask to have a 20 year old furnace checked out----they do a very detailed check and show the details and they don't try to ram all sorts of repairs at you--they actually said everything is fine for now ( guess who I'll call when I need one }--they were right on par with 2 other companies I called for estimates----awesome job"

"Very pleased with our new air conditioner installation. The salesman was very nice and explained everything to my satisfaction. The installers were efficient and knowledgeable as well. They showed up exactly on time and were finished earlier than I expected. Work areas were cleaned up, inside and out. Not even any metal shavings in the grass where the new ducting was cut. One of the nice gentlemen even explained the new thermostat they installed. I highly recommend Southport Home Services."

"Our nearly 40 year old boiler system had seen its last day. Steve with Guardian was easily accessible by phone, prompt, and helpful. He installed a new boiler and retooled the set up of our system. We re very happy with the service, speed of the install, and professionalism the guys showed. We didn t shop around much since we weren t interested in having too many people coming in and out of the house during the pandemic, but felt confident Steve was giving us good information and a fair price based on what we were told in the past and research we had done. I would certainly recommend Guardian to friends and family. I will update going forward if necessary since the system is currently a day old, but the house is as toasty as ever so mission accomplished thus far."

"This was the year my old klunker (furnace) decided to stop working. Great,just wonderful. So I picked up the phone and made a call to 1st Choice Heating. They had a technician dispatched faster than I expected. The news was not good,I needed a new furnace. I was quickly put on the schedule and my furnace was in before I knew it. Thanks 1st Choice team you were awesome from the first call to the install!!! "

"I had lost heat to my boiler late one night in February. With my family gathered around our fireplace in the living room & heat dropping on one of the coldest nights of the year, I was concerned. JB Mechanical responded first thing in the morning. The technician did a nice job of diagnosing the problem. After a few hours we had our boiler up in running. They also worked with me on the price, adjusting accordingly. A job well done by Patrick, the technician."

"Politely said, Sparky is the boss.  
We needed electricity and HDMI ran from a cabinet in our great room up above our fireplace so we could mount a TV.  Also needed cable and electricity ran to a wall in our master bedroom so we could mount our TV on the wall. 
Sparky showed up on a Friday afternoon, five minutes early.  Assessed the situation, and before he left, said he would look into how much parts/etc would cost, and he would call me with a bid.  Sunday night I received a text from him with a bid, we set up a time for him to come for the install on 8/22 at 9am.  
Sparky showed up at 8:59, and got to work.  I came home from lunch to outlets installed where I had asked, cable ran, everything was great.  He could not find the specific outlet cover for AC / Cable, but it will not be visible once the TV is mounted, so it is not of real concern.  
I was a little uncomfortable mounting the brackets for our TV on the walls, as the studs were located in odd places - and I didn't trust myself to mount a $1,000 60" plasma anywhere that wasn't on a small stand.  ha!  
I asked if he would mind installing the mounts if I kicked him some extra $$, and he gladly obliged to stay longer than he had originally intended.  He even went so far as to use his own screws/mounting bolts that were FAR superior to the ones that were provided in the kit.
Couldn't be happier.  Should we plan on doing any other electrical work / lighting in the future, Sparky will be our first call.

Install Boiler FAQs, answered by experts

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.

Safety concerns with propane boilers include proper venting to prevent carbon monoxide buildup, secure gas line connections, and regular inspection of safety controls. Professional boiler installation and annual maintenance are essential to minimize risks. Having a carbon monoxide detector installed in your home is essential for early detection of any leaks or ventilation issues.

Warmed or cooled air can escape your home through drafty windows and doors. If you notice any gaps, be sure to caulk and seal them. You can also hire a local pro for an energy audit to get a list of energy-saving recommendations. 

Finally, check your insulation. It can settle in over time and become less effective. The Environmental Protection Agency (EPA) estimates that you can save an average of 15% on heating and cooling costs (or 11% of total energy costs) by sealing leaks and making sure attics, crawl spaces, and basements have a nice layer of insulation.

You should get anywhere from three to five quotes for HVAC replacement to get an idea of the average cost of a new unit. Although this quote-collecting process can be time consuming, it allows you to compare what work is required, what type of unit you should install, and how much you should expect to pay for the service.

Generally, an oil furnace is considered safer than a gas furnace for several reasons. While both types of furnaces can produce carbon monoxide, a leak in an oil furnace is easier to detect due to the smell. Oil furnaces also don't connect to a gas pipeline, which reduces the chance of a fuel leak. Most importantly, heating oil is not combustible, whereas natural gas is highly flammable. This means there is a much lower risk of combustion or explosion with an oil furnace. However, an oil furnace can still pose a fire hazard if it tips over.
