Derr Heating & Cooling has over 30 years experience in design, service and installation of residential and commercial HVAC systems. We only install our own products to ensure our guarantees are available to all customers. Our experience allows us to better understand the complexities of air conditioning systems that other contractors overlook. While other companies want to stay within certain guidelines that make it easier for them, what we call "cookie cutter" options, we are willing to think outside of the box and provide creative yet simple solutions to complex comfort challenges. While many companies refuse to work on specialty systems, Derr Heating has the experience to service and install almost any type of heating and cooling system.

"My problem is the invoice. It was changed to reflect an increase by $81.00 plus tax. The diagnostic was quoted to me as $139.00 plus tax on two different occasions. The additional $81.00 charge was to “test breaker” which is apparently not included as part of the diagnostic process. The technician turned the breaker switch on and off, that is all, with nothing connected to the breaker panel to make any reading. That is what cost $81.25. I was told by the technician I could pay by check. I have no checks, but, if I had given a check to the technician right then it would’ve been $139.00 plus tax. That’s the billing he showed on his tablet and what I signed for with NO indication of any additional costs. I understand additional costs but we’re supposed to be informed beforehand when there are or may be additional charges. That didn’t happen My heating definitely works now but I don’t have a clear understanding of what he did. I had already checked my breaker panel several times to make sure the switch was on when the problem started. He told me my thermostat in the living room might need to be replaced. Again the only “test” for the breaker panel was turning the switch off and on with nothing connected to give any sort of reading. He definitely tested the heaters using whatever gauge he connected to the heaters and told me they were old but getting sufficient power."

Boiler repairs FAQs

The average cost to install a new water heater is around $1,300, but you can expect to pay between $875 and $1,750, depending on the kind of water heater, the size of the unit, and the professional chosen to complete the work. Tankless water heaters can push your price higher, as installation is more complicated, with prices as high as $3,500. The location and accessibility of your water heater will play a role in the project cost, as those sitting in tight spaces like a crawl space will drive up your labor costs.

It is very difficult and dangerous to install your own water heater, so we strongly recommend against tackling this as a DIY project. Not only will you need to wire your water heater, but you’ll also need to connect plumbing to the intake and outlet. Sweating copper pipes and connecting wiring properly are skills most DIYers don’t have, and even if you do feel confident you can do it, working with water and electricity always leaves the potential for electrocution. Hiring a local water heater installer is well worth the investment.

The average cost to hire a plumber is around $100 an hour but can vary between $45 and $200 an hour depending on the plumber’s experience and the repair that you need. It’s also important to note that these prices can go up on holidays, and emergency plumber rates average $150 per hour, in addition to a flat-rate trip fee of $100 to $350
