"If you want honest, straight-forward, complete, and competitive pricing for a new HVAC system, go to Bluestar Air Mechanical. Our 21-year old systems needed replacement and we began our quotation/search process. Amongst the 7 companies we inquired with, Bluestar had the most comprehensive explanation, set of offerings, and was patient with us as we completed our comparisons. John promptly and completely answered all of my questions ranging from installation, future usage, efficiency, and advice on what was necessary vs an accessory. Lynn at the office was prompt and courteous on all of my scheduling, dispatch, and payment inquiries. You'll get top notch quality, service, and friendliness if you work with Bluestar for your HVAC replacement needs."

"My AC failed and I had limited time to find a good solution, I made a phone call to Relax HVAC based on the online reviews and it was a great decision. Nasser came to check the situation, he gave a very detailed and comprehensive overview of the situation and provided with the options I had. I decided to replace the unit, Nasser went above and beyond to find a unit delivery service but there was nothing available over the weekend so this gentleman went for unit pick up himself and finished the installation within a day from my initial call. Moreover, the provided price was very reasonable.I can't be more happy with the outcome and highly recommend Relax HVAC"

"Everything went well!  They did accidentally bring the wrong equipment at first because of a paperwork mixup at the home office, but they corrected it quickly and even upgraded my outdoor heat pump unit as compensation for the mistake.  That did cause them to have to drive to the Lennox distribution center and back, setting the install completion back a couple of hours.  I guess for that I have to knock them on "quality".
But other than that, everything went smoothly.  They were professional and courteous.  They also called back the next day to check on everything and make sure that everything was satisfactory and to apologize for the mixup.
Thanks, Modern Mech!

"It was a superb experience. From the visit by Bruce the sales representative to the installation day to the follow-up from Petro, every single person we interacted with was helpful and professional. When Bruce arrived to do the assessment, we spent time going over the heating needs in the house. After a thorough inspection and measurement of the house, we sat down. He showed me a few options, all of which were going to provide good service. I ordered a unit at the end of that meeting. The installation day was just terrific- the entire work crew that showed up were everything I would hope to find: Upbeat, informative, hard-working, focused. The job was finished before end of day as promised. The heater room is now immaculate, with new piping and a new heater. It was like watching a pit crew at a NASCAR race. Everyone had their tasks, they moved carefully but quickly. The materials were all laid out in order, etc. Just a totally professional approach to their work. The crew boss answered any questions I had. The follow-up for a normal inspection of the furnace chimney was scheduled the day after the installation. I’ve gotten calls to insure we are satisfied with the work. Satisfied barely covers it- I am pleased to write this kind of review. Without hesitation I will recommend Petro to friends and family throughout the Philly area. Peter A. Elkins Park"

"Briggs Heating and Cooling has been our go to provider since we renovated our home in 2005. They are experienced, supremely responsive and personable professionals who truly care about their customers. They go out of their way to get it right. We have trusted them so much that we introduced them to my elderly parents’ home years ago. My parents have adopted them ever since. We have had several projects this year alone, some routine maintenance, some much more complicated. Each project was handled the same way. First, my parents have an old AC and “Trevor’s guys” come out every year to service it. Their gas heater required a new switch which, because it was an old unit, took a lot of effort to find and replace. Next, our newer AC had a valve malfunction, and Briggs’ went way out of their way to properly diagnose the problem. As a precaution, we received a second opinion. Not only did Briggs’ diagnose the problem properly, they fixed it at about a quarter of the cost that the other service provider would have charged. Most recently, a couple of weeks ago, a leak was detected in my parents’ newly installed gas fireplace logs which Briggs had not installed. They met me at my parents’s home within an hour and had it repaired in another hour. And their prices are always extremely reasonable. This is small business done right. In northern Virginia, they are a breath of fresh air."

Install Boiler questions, answered by experts

Some high-quality steam boilers come with 10-year warranties, but a well-installed, properly maintained model can last at least 20 to 25 years. Learning how to clean a boiler, getting an annual professional service, and keeping up with maintenance and repairs on your heating system are all important for getting the most out of your model. 

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.

The main difference between an outdoor wood furnace versus an outdoor wood boiler is what each appliance is heating. An outdoor wood furnace burns wood to create heat, which warms the air and moves it through the ducts in your home. An outdoor wood boiler uses the heat from burning wood to warm water, which goes through pipes to radiators in the home.

Oil boilers provide reliable heating, efficiency, and long-term cost savings compared to electric options.

Unless they are connected to the same system, boilers and water heaters will both need their own expansion tanks. The only case they wouldn’t have separate expansion tanks is if the boiler is pulling double duty and managing a heating system while also supplying hot water for a home. In which case, you may not need a hot water heater.
