"Swimmingly. I interviewed quite a number of HVAC companies for this job by sending out an RPF (Request for Proposal), and Bob Mamayek was unquestionably the most thorough in his on-site evaluation. Installation crew was fantastic. This is a small shop, and it was a true pleasure to have a team of regular guys just getting the job done. I recommend them without reservation. I almost gave them a B for responsiveness because Bob doesn't do a lot of email, but I realized while typing that this would be completely unfair, for two reasons. A) Bob might not respond to email with email, but he did always respond with a phone call. Frankly, that is better on many counts. B) This ignores the amazing response to my RPF, which was both timely and thorough. So, really, this says more about my email-centric life than Mamayek's responsiveness."

"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."

"Guardian Heating and Cooling was very professional putting in our new boiler system. Steve was on time, explained everything that was going on, answered any questions about the project, was efficient professionally, and left the area as if there was no work that had happened there. In my opinion an A+ service."

"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.

"He ended up not only selling us a new A/C unit (on sale) but gave us an amazing deal to replace the furnace at the same time. The installation took longer than I expected - but I was provided logical reasons for the time AND the poor guys did some of the work in the pouring rain. We've only had the new system for a couple of days, but I am confident that it will be an upgrade from our previous system - especially when they said "Feel Free to call us any time, and by 'feel free' I mean definitely call us if you have any questions or issues""

Install Boiler FAQs, answered by experts

If you're often struggling with radiator issues like chilly spots, leaks, or annoying noises, those are common indications that your radiator may need to be replaced. Corrosion, uneven heating, and persistent hissing sounds are common issues as well. When repairs become a regular chore and your home’s energy bills start to rise, a new radiator will bring the comfort and savings you need.

Most experts recommend getting three to five HVAC quotes from licensed, insured, reputable local heating and cooling companies. Getting multiple detailed HVAC quotes (but not too many) lets you compare the equipment, services, and prices of several contractors without being overwhelmed by options. It can also let you see if one contractor’s prices are much higher or lower than the others and give you a chance to ask for clarification. That way, you can weed out any contractors who aren’t providing quality services or materials and find the company that best meets your budget, quality requirements, and long-term goals.

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.

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.

Boilers are equipped with multiple safety features to ensure safe operation. These include pressure relief valves to prevent overpressure, temperature high-limit switches to avoid overheating, and flame failure safety devices in gas boilers to cut off the gas supply if the flame goes out unexpectedly. Low water cutoffs prevent operation with insufficient water levels, and pressure gauges help monitor pressure levels. Ventilation and flue systems prevent the buildup of harmful gasses. Boilers often feature error code systems for automatic shutdown during malfunctions and gas leak detection for safety. Regular maintenance is crucial to ensure these safety features function correctly.
