"I wish I would have contacted them sooner. If you're like me and went with the bigger names before this company... it's NOT too late to switch. Bite the bullet and let Hurlburt go and use Comfort and Cooling! They communicate much much better than the other company. Ever since starting with Hurlburt it felt like they try to scam you in every way! Not this company. And during their visit they found numerous things that Hurlburt either completed missed, or was not interested in sharing with us. Will continue using this company going forward! 10/10"

Heating Oil questions, answered by experts

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

You need to service an HVAC system about twice per year, with a service including an inspection and basic maintenance. It’s best to schedule maintenance in the spring (after the furnace has been running and before the AC kicks on) and in the fall (after the AC worked hard all summer and before winter’s first chill arrives). 

Regular HVAC services will keep the system working as efficiently as possible, saving you money on utilities and larger repairs. HVAC maintenance costs around $250 per visit, while bigger repairs from forgotten upkeep could cost thousands.

Leaks, poor airflow, reduced efficiency, and loop blockages are common problems requiring service.

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.

You can expect a geothermal system to last for years. According to the Department of Energy, the underground infrastructure for the heat pumps lasts about 25 to 50 years, which includes the pipes buried in the soil. The actual heat pump itself has a life span of around 25 years.
