Carbon monoxide concerns & replacement recommendations

Told you need new equipment? Get a free second opinion.

If another company has recommended replacement, we’ll review the findings and explain whether repair or replacement makes sense. A carbon monoxide or heat exchanger concern deserves careful testing and a clear explanation. If replacement is needed, we’ll give you our own written quote. There’s no obligation to buy.

Free second opinions apply to equipment replacement recommendations. Repairs and other service work are quoted separately.

Real people. Work you can see.

The team behind the name.

We test before we recommend, explain the price before you approve the work, and treat your home with care.

Useful answers before you call

The questions we get most.

What does it cost to have someone come out?
The diagnostic is $129 for the first system in regular business hours and $125 for each additional system on the same visit. We check the equipment, explain our findings, and give you the repair price before approved work begins. Replacement estimates are free and separate. After hours it is $275 for evenings, weekends, and daytime holidays, and $375 overnight and on holiday evenings. Maintenance plan members pay $99 per system at any hour.
Do you answer at night?
Yes, a real person answers 24/7. For urgent service, call or text so we can check availability and explain the visit fee. Online booking is for future appointments and does not guarantee service today.
Can I see prices before booking?
Yes. We publish diagnostic and maintenance pricing, and our install estimator shows installed starting prices. For replacement work, we confirm the equipment, installation scope, and final price before you approve it.
Should I repair or replace?
We look at the actual fault, safety, equipment condition, repair cost, and your comfort needs. Age alone does not decide it. We explain whether a repair makes sense and discuss replacement when it is worth comparing.
Where do you work?
We serve Delaware County, Chester County, the Main Line, and nearby communities, including Media, Glen Mills, Garnet Valley, Wallingford, Springfield, Aston, Newtown Square, Havertown, Broomall, and West Chester. Call or text your ZIP code if you are unsure whether we cover your home.
Do you work on gas and oil systems?
Yes. We service gas and oil furnaces and boilers, including hot water and steam systems. We also work on combination boilers, tank and tankless water heaters, heat pumps, and ductless systems.
Can you help me use less oil?
Yes. We help you compare gas, propane, heat pumps, ductless, and dual fuel, as well as separate hot water where it makes sense. We check your home and the work required before recommending a conversion.
Can you give a second opinion?
Yes. If you’ve been told you need new equipment, ask us for a free second opinion on the replacement recommendation. Text us the report and any photos, or call to arrange the visit. Photos help us understand the concern but do not replace on-site testing. Repairs and other service work are quoted separately. Leave equipment shut down for safety off until checked.
What should I send by text?
Tell us what is happening, your town, and the type of equipment. A clear photo of the model label and any error code can help us prepare. We will explain whether a service visit or a replacement estimate is the next step.
