A Boiler Repair Expert Near You

Your boiler is the heart of your heating system, but Portsmouth residents often overlook it. When it breaks down, it can increase your gas usage, lead to inconsistent pressure, and become noisy. A failed boiler can generate pressures of over 20 PSI. Once that builds beyond tolerable limits, in a worst case scenario it can cause an explosion, so boiler repair needs to be carried out as soon as you notice symptoms. Not seeing to it straight away carries genuine risks to your safety. No1PHD will remove the stress involved in the repair process, racing in quickly and executing your repair without disrupting your family life. We perform our work with pride because you don’t deserve any less.

Signs that You Need a Boiler Repair Man

Not all boiler problems announce themselves dramatically as a massive leak or explosion. A faulty unit could lead to overheating, and if your boiler won’t turn off, the consequences can be catastrophic, so look for subtle signs of breakage. Unusual whirring or whistling, leaks, and strange smells are all signs that your unit needs work. If your energy bills are climbing, your boiler might be responsible. The distance between a minor symptom and a big problem is often short, and the sooner your repair is handled the better. A quick repair is generally more affordable than a slow one, preventing expensive destruction over the longterm. It’s critical to find a service provider who will schedule your work as quickly as possible, understanding that heating is essential to your comfort. All those elements make No1PHD better than its rivals. We put your needs first, and we don’t waste hours or days to schedule your repair.

The Importance of Expertise

Boiler repair is demanding work that requires a qualified team of gas-safe engineers, and that’s precisely what we provide. Boiler expertise isn’t enough, though. Your heating system is made up of several components, and each one fits into, and influences, the next. That requires a holistic perspective of every part of your heating technology. Our Portsmouth team is qualified to deal with leaks, drainage problems, and plumbing, so they can maintain your system as a whole. An unqualified repair team can wear away the integrity of your system, putting your family’s safety at risk. That’s why our team is CRB-checked, fully insured, and qualified. They can work with a wide range of different components, always going beyond the call of duty.

Couldn’t have asked for a faster resolution to our drainage conundrum. Nothing was too much for these guys who were brilliant throughout.

Long-term Boiler Repairs

Diagnosis is just the first step of a repair. Many common boiler breakages are just a symptom of a greater problem, so a basic mend isn’t enough. If your water is hard or other parts of your central heating system are operating sub-optimally, even the most thorough fix won’t last. That’s why our team has deep knowledge of your entire central heating and plumbing system. They’ll offer solutions to common problems that erode and wear your boiler down prematurely. Once they’ve completed the repair, they’ll recommend a maintenance plan and advise you on how you can keep your boiler healthy.


Cutting Costs

Our team has enough practical solutions up its sleeves to make your repair go smoothly, but not all breakages can be repaired. Sometimes, boiler replacement is the only option. Boilers can be expensive, and few repairmen have the expertise to guide your new purchase. Our engineers do. They’ll advise you on whether you need a regular or combi boiler based on your home’s design and size. They’ll keep your components at top efficiency without breaking the bank. We even have financing options if you can’t afford to cover your work straight away.

After noticing that the house was unusually cold, we found that the heating wasn’t coming on and that our hot water had also failed. We called the team at No 1 PHD who dispatched an engineer to investigate. After discovering that the culprit was a faulty boiler part, they ordered in a new part and got it fitted as quickly as possible. The guys were great, and we couldn’t be happier.

For days, we’ve noticed a foul smell coming from outside and a gurgling sound coming from one of the drains. Whenever it would rain, the area around it would flood slightly and take ages to drain. We tried buying drain unblockers, but none seemed effective. Eventually, we turned to No 1 PHD and were left wondering why we didn’t do this sooner.
