"The salesman was knowledgeable, professional and explained everything about the shower install well. I gave him a deposit of $3200. I did not hear from anyone so after 3 days I called but no one returned my call. Called back again a week later to cancel the order. Left a long message stating I did not want to cancel the order but was concerned because no one returned my calls. Finally, received a call from a regional manager. He connected me to a local manager who set up an install date a week later. The installers were polite and professional. Gave me some helpful advise. Job was completed in less than a day. The shower door came a week later. I have had the shower for over a month. It is beautiful. I love it. Quality work. I would highly recommend Premier Home Pros."

Boiler Repair questions, 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.

Regular inspections, filter replacements, and professional tune-ups keep the system running efficiently.

Once you know where your bleed valves are and how to use them, bleeding out heaters is a quick process. Expect it to take around 10 to 20 minutes, possibly longer if you have a lot of heaters or are still learning how they work. If you have a central bleed valve on your boiler, the process still takes the same amount of time. Make sure you have any keys necessary to turn the bleed valves on. Without bleed valves, the process should take around three hours.

Schedule annual inspections, check for leaks, and bleed radiators to ensure efficient operation.

Most repairs take 2-6 hours, but extensive repairs or part replacements may require a full day or more, depending on availability.
