Heating systems we repair

Signs your heat needs a look

  • No heat, or not enough

    A failed igniter, flame sensor, thermostat or circulator pump is behind a lot of no-heat calls.

  • Banging, clanking or whistling

    Common in boilers and radiators. Often trapped water or air in the pipes rather than a failing boiler.

  • Short cycling

    The burner fires and shuts off over and over, which wears parts and wastes fuel.

  • Some rooms stay cold

    Air-bound radiators, a stuck zone valve or closed-off ducts can leave part of the house behind.

  • A yellow flame or soot

    A sign the burner isn’t burning cleanly. Have it checked soon, and keep carbon monoxide alarms working.

  • Higher bills, same comfort

    A system running longer to do the same job often needs cleaning, adjustment or a worn part replaced.

Fix it first

When the heat goes out in January you need it fixed today, not next week. We come out quickly and find what actually failed. Most heating calls come down to one part: an igniter, a flame sensor, a circulator pump, a zone valve or a pressure switch. When the part is on the truck, the repair often happens on the same visit.

If a part gets your system running safely for another five winters, that’s what we recommend. You get the repair price before we start, and a straight answer about how much life the system has left.

Boilers, radiators and older homes

Many Philadelphia and Main Line homes built before the 1930s still heat with a boiler and radiators, and a well-kept boiler can last decades. We work on steam and hot-water systems as well as furnaces and heat pumps, all makes and models. If some rooms never get warm, the fix is often in the radiators, valves or zones rather than the boiler itself.

When replacement makes more sense

Sometimes a system is too old, too inefficient or too expensive to keep repairing. When replacement is the honest call, we show you the numbers and your options, and new systems are usually installed the next day with full factory warranties and 0% financing on approved credit.

Catch it before it breaks

Most winter breakdowns start as small problems. Our $54 Seasonal Maintenance visit in the fall cleans and checks your furnace or boiler before the first cold night.

What customers say

4.9 stars from 300+ Google reviews.

Same-day service. Next-day install.

We used SK in two houses. When our AC unit went out on a hot summer day, SK showed up & fixed it, same day. When our heat stopped working in the winter, SK showed up & fixed it, also same day, both happened to be weekends. Saki is so knowledgeable. He helps you understand the issue, doesn’t upsell you (not to mention his pricing is so fair!), and is quick to respond. The utmost professional & incredibly kind, I can’t recommend the SK team enough.

Abby K., customer at two homes

Fixed in under 30 minutes.

Saki was the best HVAC tech I have ever met. He was easy to schedule with, on time and very quick to diagnose our issue and offered a way to repair our system with an honest assessment. Our whole appointment was less than 30 min with a new part installed (he had it available in his truck). I appreciate that he is a small business and does not try to sell you on a whole new HVAC system like bigger companies have always done with our older system when there is a reasonable fix. I will 100% use SK again for my HVAC needs. If you are interested in maintaining vs replacing call SK.

Lily C., repair on an older system

Fair prices, careful work.

Incredible service and knowledge. Saki took the time to diagnose our issue, answer our questions, and did the repair quickly and effectively. The price was very fair and reasonable. He really cares about his craft and it shows. Thanks so much!

Heating repair questions

Why is my boiler or radiator banging?

In steam systems, banging usually comes from water trapped in pipes that don’t drain back to the boiler. In hot-water systems it can be air in the lines or a failing pump. Either way it’s often fixable without replacing the boiler, so have it looked at before assuming the worst.

Is it worth repairing an old furnace or boiler?

Often, yes. A well-kept boiler can last decades, and many furnace problems are one part. We diagnose it, tell you what the repair costs next to a replacement, and let you decide. If replacement is the better value, we’ll say so and show you why.

Do you offer emergency heating repair?

Yes. We answer no-heat calls 24/7 at (610) 937-5357. Customers have told us we’ve come out the same day, even on weekends.

Is there still a tax credit for a new furnace or boiler?

The federal 25C tax credit ended for equipment installed after December 31st, 2025. PECO still offers rebates on qualifying high-efficiency furnaces and boilers, but it lowers its gas rebate amounts for requests on or after October 1st, 2026, so we check the current rebate when we quote.

What should I do if my carbon monoxide alarm goes off?

Leave the house and call 911 or PECO’s gas emergency line first. Once the fire department or PECO says it’s safe, call us and we’ll find the cause before the system runs again.

Get your heat ready before the first cold night with $54 Seasonal Maintenance.

We test your furnace or boiler, check for carbon monoxide, clean what needs cleaning and tell you honestly how it looks. No pressure to replace anything.
