Q: What types of heat pumps are there?

• <div><p>There are three main types of heat pumps. An air-source heat pump system is the most common and has two parts&mdash;an indoor air handler unit and an outdoor heat pump unit. A ductless heat pump system functions similarly to an air-source heat pump system but doesn&rsquo;t need ductwork to distribute the air. A geothermal heat pump system pulls heat from the ground to help heat your home. </p></div>

Q: Do NATE-certified technicians cost more?

• <div><p>NATE-certified technicians may charge slightly higher service fees compared to non-certified technicians. This is because NATE certification signifies a higher level of expertise and professionalism, often leading to more efficient and effective HVAC repairs and installations. While the upfront cost may be marginally higher, NATE-certified technicians can potentially save you money in the long run by reducing energy consumption, preventing frequent breakdowns, and extending the life span of your HVAC system. When looking for a <a href="https://www.angi.com/nearme/hvac-companies/">local HVAC company to hire</a>, it never hurts to ask about NATE certifications. </p></div>

Carlos and his team was very professional. They were always on time and worked very hard painting in extreme heat. The communication was easy and fast. They did an outstanding job, and we highly recommend them. We will hire them again!

Very responsive staff. Arrived on time and were able to get replacement part pretty quickly to repair hot water problem (did not need to buy new tankless water heater). Work looked to be done very well. Best of all, their cost was much lower than other estimates I received.

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

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.

There are three main types of heat pumps. An air-source heat pump system is the most common and has two parts—an indoor air handler unit and an outdoor heat pump unit. A ductless heat pump system functions similarly to an air-source heat pump system but doesn’t need ductwork to distribute the air.
