Dannemora's unique heating challenges

About 161 nights a year below freezing, when aging heating systems give out

The oldest blocks in town run heating systems decades older than the newer builds toward Saranac

First frost typically lands around October 14

Seasonal timing

With first frost around October 14, the controls start switching daily after that date, and a marginal transformer usually gives up within weeks of that.

Common questions

How much does heating repair cost?

It depends on the job and how bad the problem is. That is why the first step is a phone call. Describe the problem and get your free estimate on the phone, with upfront pricing.

Will I talk to a real person?

Yes, you will.

Do I need to fill out a form?

No forms and no waiting on emailed quotes. One phone call is all it takes.

Can I get help at night or on a weekend?

We have heating pros ready to help families in the community 24/7, but moment-to-moment availability depends on demand. Call to find out how soon we can service your home.

Should I wait to call?

You already know that heating problems don't go away on their own. And waiting just increases the risks to your house. Heating pros see this hesitation all the time. Instead of regretting not calling earlier, just make that 2-minute call now and get your free estimate.

People also ask

Why would the whole system go dead at once?

A failed control transformer takes the thermostat, the zone valves and the relays with it. The boiler itself may be perfectly healthy.

What makes a transformer fail?

Age, heat and a short somewhere on the low-voltage side. A repeated failure usually means the short is still there.

Is that an expensive repair?

The part is small, though the real work is finding why it failed. A technician traces the low-voltage circuit rather than just swapping it.

Does old wiring make it more likely?

It does. With 81 percent of the housing predating 1980 here and around Altona, plenty of low-voltage wiring is decades past its best.
