"AHS is ok. They cover repairs of most everything under the roof of your house. The companies that contract with them are not always the best. You call AHS with the issue, they send a fax to the repair company and give you the contact info. If they don't contact you within 24 hours, you call them. Sometimes they answer, sometimes they don't. When they arrive (usually three days or so later), they service the item. if it has issues within the 90 days, you call AHS again, they are sent out with no charge. If the serviceman decides the unit is unrepairable, AHS will allow you to choose a replacement from their listing (usually not as good as what you have) they will install and remove your old item, or give you wholesale amount to buy and install your own. Prices vary on what you want covered and what you want the copay to be, plus where you live. For me it is 49.99 per month with a 75.00 time of service order. You can have more than one item serviced at the same time under the same fee. If you have a SEAR product the repair guys are great. Not that wild about the other ones they send out. But it is a big savings compared to calling someone on your own. The cost of service is only the 75.00 copay."

Boiler Repair FAQs, answered by experts

Yes, many HVAC professionals offer emergency repair services for furnaces and other heating systems. These services are especially common during the winter and colder seasons when functional heating is crucial.

Always consult your manual for specific pressure numbers. Many expansion tanks come pre-pressurized at a specific PSI range, anywhere from 12 to 40 PSI, designed for a range of home boilers. You should not have to pressurize an expansion tank yourself, only the boiler system. If your system has a tank that needs to be manually pressurized, this is generally a job for professionals and their tools.

Deciding whether to repair or replace your HVAC system largely depends on its age, the cost of repairs, and its overall performance. If the system is over a decade old and requires frequent or expensive repairs (e.g., totaling over $5,000), replacement is often the more cost-effective choice, especially if the warranty has expired. It is usually worth repairing a newer system, but if it is approaching the end of its typical 15- to 25-year lifespan, replacement might be a better long-term investment. Signs that you may need a replacement include increased humidity, higher energy bills, uneven heating or cooling, and excessive dust. Before deciding, ask your HVAC contractor to check if any parts are covered under warranty, which could save you money on repairs.

In most cases, repairing a radiator is more affordable than replacing it. A typical repair may cost between $100 and $200, while a replacement can average $1,500, with a range of $250 to $2,500 depending on the unit type. Radiator issues are often simple fixes for a professional, such as a blown fuse, malfunctioning thermostat, or a loose valve, and can take less than an hour. However, if the long-term costs of fixing the radiator are higher than replacement, it's better to get a new model. It is recommended to consult a heating expert to diagnose the problem and determine the best solution for your situation.

Repair costs range from $200 to $800, depending on the issue and required parts.
