"So we have a problem with this installation and this vendor is not cooperating to fix a problem with this brand new install. Not only did he not complete signoff which we needed for maintaining our warranty but the testing they did was designed to make us believe it was working when it was not. When we tried to get him out again he pretended to be super busy and all booked out when in reality he did not want to come out on a job he was not getting paid for because we already paid him! In good faith! Under the impression this was a reputable company that would back up their work knowing full well it was a brand new super expensive installation where most of the work was done by my contractor and all they had to do was connect the handlers, test the system and certify it. They would not certify it and made excuses but never returned. It never worked. We can not get them back out to fix it because they've already received payment. BEWARE OF THIS COMPANY. THEY ARE NOT REPUTABLE."

Heating Oil questions, answered by experts

Your HVAC manufacturer will give you instructions on how often you should service your system. Have your unit professionally serviced at least once a year when in doubt. 

Heat pump systems are different because they provide heating and cooling solutions for your home. In this case, you should have it serviced at least twice a year.

Regular inspections, loop flushing, and checking heat exchangers help extend system lifespan.

Most HVAC companies charge a flat service call fee of between $75 and $150, which includes traveling to your home and inspecting your system to find the underlying problem. Keep in mind that these prices only include diagnostics and the actual repairs will usually be billed separately. If you’re calling for routine service, the service call will be included in your inspection and tune-up, with the total sitting around $150. Your prices could be a little higher if you have a very large home with multiple condensers and air handlers, as inspections and servicing take longer.

Costs depend on system age, type, labor, and whether part replacements are necessary.

HVAC systems usually last between 10 and 30 years, with most having a lifespan of around 20 years. Factors that impact a unit’s life expectancy include which brand you choose, how often you use it, and how well you maintain it. To make sure yours lasts as long as possible, make sure to keep it clean and schedule an annual service with an HVAC technician.
