It went very well. Clark's Plumbing & Heating plumbers do great work. I was surprised at the cost but then I was reminded that the hot water heater is a hybrid system that works in conjunction with the furnace (which is more expensive than a stand-a-lone hot water heater).

They were okay. In fact, in the week it destroyed the flooring under the hot water heaters and they were willing to rebuild that part to make that solid so that there will be no issues with the hot water heaters. They did a good job and the price was reasonable under that circumstances.

This is simply a backup heat pump you’ll likely never need and not an alternative heat source.

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 local HVAC company to hire, it never hurts to ask about NATE certifications.

It’s a better use of energy (and your money) NOT to run an ERV system all the time. Most experts recommend that you cycle your ERV system on and off throughout the year. However, the recommended advice could change based on your climate, the number of people in your home, the size and style of your home, and your heating and cooling system. Contact a local pro for more specific advice.

Most maintenance checks take 2-5 hours, though extensive repairs may take longer.
