"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."

"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.

"Mr. Holland's was exceptional from the first phone call to followup courtesy calls after the install. They are very knowledgeable and explained all aspects of the process. There customer service, pricing and experience showed in all aspects of this project. Also they have a 10 Labor Warranty! I had a few other estimates and those companies only offer 1-3 years . So would i recommend Mr. Holland's ? A most Definite YES"

"The pressure relief valve of the boiler system of the house we recently purchased had been dripping constantly since we moved in, so we thought it best to have the whole system checked out before scheduling a repair. I purchased a seasonal tune-up from an Angie's List special offer ($99) in order to have the entire system looked over, and the owner got back to me within an hour to schedule an appointment, and was able to come out the same day. He arrived about an hour later than the scheduled appointment time, but called around the appointment time to let me know he'd be running late. After performing the tune up, he looked over the system and let me know what was in good condition, and what could use eventual repair, and advised that such tiny leaks don't usually require immediate attention and to put it off until the off-season (two of the on/off valves had tiny drips, and the automatic fill valve wasn't responding to pressure changes very well). He also corrected the boiler's thermostat, which was set to almost 210 by whomever serviced the house before we bought it-- 30 degrees hotter than it should be, which causes problems long-term. He quoted me for the dripping pressure relief valve ($90 for the service call and one hour of labor, around $100 for the valve) that had prompted the appointment, and offered to come back the next day within a 2-hour window. Ran about 15 minutes later than the 2-hour window on the second day. During the job, two of the pipes on the relief valve were corroded beyond being able to be reused (piping was installed in 1938) and he had to run and get new pipes. This stretched the job closer to two hours (including the time he was gone getting the unexpected parts), but I was still only charged for the original hour that he quoted, and the replacement pipes added $15 to the job. He was thorough, explained everything I might need to know to extend the service life of the boiler and system, and was very friendly. Overall good experience-- we plan to return to Faithful Heating for our annual tune-up in future years."

Install Boiler FAQs, answered by experts

The best way to compare HVAC quotes is getting a few detailed quotes from local companies with good reputations. Then, go over the quotes line by line. Protect yourself by insisting on in-person estimates that include equipment manufacturer names, model numbers, SEER ratings, amounts and numbers of materials, details of warranties on equipment and labor, and other specifics. 

Knowing the exact equipment and materials is the only way that you can fairly compare quotes. Quotes that are much lower than others can be a sign that the company isn’t providing the best quality service or materials.

The right type of HVAC system will depend on several factors, including your climate, budget, preferences, and existing HVAC setup. For example, if you live in an area that experiences extreme weather, then a split system would likely be the best option. Or, if budget is a concern, consider installing a ductless system in just one room.

A home radiator works by using radiation and convection to transfer heat throughout your home. Electric radiators use metal to conduct heat and warm the air, which then rises to warm the room. Steam and hot water radiators work with a boiler and piping system to pump thermal energy throughout the home. Hot water radiators use a boiler to heat the water before circulating it to the radiator, while steam heating radiator systems convert the heated water to steam before circulating it out. When the water or steam cools, it travels back to the boiler to be heated again.

No, there isn’t always water in radiators. In a one-pipe system, water is constantly circulating from the boiler to the radiators and back. In a two-pipe system, water travels through two separate channels: one that goes to your radiators and one that returns back to the boiler so it can heat up again.

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.
