"They charged $98 to come give me an estimate for swapping our a shower valve cartridge, which was fine, but the pricing they provided was completely unreasonable, $1,000. They were unwilling to provide any detail for the price. I ended up buy the part myself for $30 and replaced it in 30 minutes."

"we had a Bosch boiler hot water combo system installed in the spring of last year for $9500. We used the heating system on some cool days and nights, so it seemed to do the job of heating our home. This year is the first time we have used it for the entire winter. If the temperatures are mild the system works okay. If the temperature drops below 30 degrees it will not heat our home. We were able to keep the house warm thanks to our pellet stove. In Hine sight, We wish we would have stayed with the conventional boiler system for about half of what we paid for this inadequate system. buyers know what you are getting into before you buy."

Heating and Air Conditioning questions, answered by experts

The simplest indicator is how long it’s been since your last tune-up. You should schedule an annual AC tune-up each spring. Beyond that, there are multiple signs that your AC needs a quick check by a professional. These issues include higher-than-average energy bills, decreased air flow from vents, higher indoor temperatures, and an air conditioning unit that stays on all the time or frequently turns on and off.

Your air conditioner can temporarily run with a dirty filter, but it won’t work as efficiently. It will need to work harder to blow cool air throughout the room or house, and this can eventually cause the air conditioner to overheat or die prematurely. It’s much more cost-effective to clean or replace filters than to pay higher utility bills each month and replace the entire AC unit more often.

Yes, it is possible. An electrical fire can break out if the compressor has inadequate ventilation. When it overheats but doesn't have a proper thermal cutout, this can cause the motor to short-circuit and catch fire. This risk is exacerbated if flammable materials, like dust and fallen leaves, are clogging the unit. The compressor overheating won't start a fire by itself, but poor maintenance and installation can increase the risk once it hits its breaking point and short-circuits.

A damper motor can last up to 15 years, but it can wear out more quickly than that if you run your HVAC unit a lot. So you might expect a longer life in a colder climate than if you live in a warmer climate.

A few drips here and there should not be cause for concern, but if your unit is leaking a large amount of water, then it’s advised that you stop using it until the problem is identified and a solution is determined. The more you use it during a leak, the more issues it will cause.
