"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"

"Bob visited our house, worked with us on selecting a unit, and provided an estimate for the work the same night. As for the installation, within two days everything was installed and one wouldn't have even known anyone was working on our house except for the new ceiling vents. He did a great job and we would hire his company again. Bob made the whole process very easy."

"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."

"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

Since your boiler keeps you warm and provides hot water to your home, you’re likely to notice issues with heating in your living space right away. The most obvious sign that your boiler is breaking is not getting any heat or hot water. You might also hear some odd sounds coming from your boiler during operation, the flame in your gas boiler is not blue, the pressure is inconsistent, or your boiler is using more energy than it should. If you notice any of these signs, be sure to call a pro right away.

The average lifespan of a boiler is typically between 15 and 20 years, though some may last for as little as 10 years while others can reach 30. A boiler's longevity is influenced by several factors, including the quality of the unit, proper installation, and consistent professional maintenance.

The material also plays a significant role. Older boilers made from durable cast iron can last for over 20 years, with some functioning for up to 50 years. However, it's important to consider their lower efficiency, which can lead to higher utility bills. Modern boilers, often made from steel alloys, are designed to withstand high pressure and temperatures and have an average lifespan of about 20 years.

To maximize your boiler's lifespan, ensure it is installed correctly, have it professionally maintained each year, and address any necessary repairs immediately.

The cost to install a steam boiler varies depending on the type, fuel used, and your house size. The average cost to install a boiler is $5,900. You could spend $2,000 for a basic electrical steam boiler or up to $9,000 for a high-efficiency oil-burning steam boiler. Boiler installation is a job that’s best left for professionals to complete, and, in some states, only licensed installers can legally complete the job.

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.

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.
