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."

"Wow, these people were great! After seeing another company struggle to get two very old fas fireplaces to work, our property manager was directed by another fireplace repair place (who no longer services gas fireplaces) to call Lifetime. They sent Travis McKibben to our home, and he was fast, efficient, and most of all, he got the job done and done well. He really knows what he's doing, and is a really nice guy too. If you have to get service on a gas fireplace (especially an older model), or need HVAC work, I highly recommend this company and this technician."

"A prompt and thorough response, unlike simply informing me that there was nothing they could do, they actively researched the warranty on my current system (expired and void due to builder installation) before discussing a replacement option. I was then presented with several options, each accompanied by a quote. When asked, they recommended that I opt for a more economical quote that better suited my usage and requirements. I highly recommend this company. They were punctual and worked diligently, even during the peak summer months in the hottest room in my house (the attic). I will certainly recommend them to any of my friends and will utilize their services for any future needs related to air conditioning or furnace repair, as well as routine maintenance."

For 45 years we’ve been making Puget Sound homes the most healthy, energy efficient and comfortable homes in the country. Our experienced team brings decades of expertise installing and maintaining the most innovative and efficient technology. As a Mitsibushi Cooling and Heating Diamond Contractor, Evergreen Home Heating and Energy has some of the world's most efficient and innovative products available.
"We had Evergreen Home Heating and Energy install a new water heater and furnace, and unfortunately, the quality of their work has been disappointing. Recently, I noticed several issues with the intake and exhaust pipes. Several hanger straps attached to the wall are broken, and one of the joints on the water heater exhaust pipe is leaking water. I suspect this leak is caused by the imbalance due to the broken hanger straps. I expected a professional and reliable installation from Evergreen Home Heating and Energy, but these problems indicate a lack of attention to detail and quality. Based on my experience, I cannot recommend Evergreen Home Heating and Energy. If you’re considering them for your home needs, be cautious and perhaps look elsewhere."

"I requested an HVAC service call quote from G&S Heating through Angi, and received a "deal" via Angi for $129. I chose them partly due to that price. G&S Heating ended up billing me $280, and said that was an old outdated deal and would not honor it. Irresponsible and incredibly poor customer relations. Also, the technician they sent did not seem very knowledgeable or experienced. He said the thermostat reading issue I was having would require another service call and the possible replacement of an expensive circuit board. I ended up fixing the problem myself. I will not be using G&S Heating again."

Knowing how long your existing HVAC units can last is essential to determine if you need a repair or replacement. Typically, most modern air conditioning units can last between 15 to 20 years, and most furnaces can work properly for 15 to 30 years. If your HVAC system is on the older side and you decide to replace one unit, it might make sense to replace both simultaneously to save on costs and future hassle.
While different HVAC contractors might offer higher or lower prices than competitors, the best time to replace your HVAC system is when customer demand is low. The beginning of summer and the beginning of winter bring the most demand for HVAC systems, so if you can, consider replacing your HVAC units in the early spring or fall. Many HVAC companies offer special off-season coupons that help lower the overall cost.
The average cost to hire an HVAC contractor is between $50 and $150 per hour if charging hourly. However, some HVAC contractors will charge a flat fee by the type of service they are performing—for example, an inspection can cost between $150 to $500. Keep in mind that emergency repairs—which are made after business hours or around major holidays—generally cost more than scheduled repairs.
Yes, most states require HVAC technicians to be certified, and for good reason. Hiring an unlicensed HVAC technician could lead to poor quality work, costly future expenses, and potential code violations.
As you browse our pro listings, take note of the “Angi Approved” badge. Angi Approved businesses meet our standards for certification which include:
The owner, principal, or relevant manager passed a criminal background check
Required to have applicable state and local licenses
Maintain an average star rating of 3.0 or better on our network, if they have at least one review
Paying to advertise their services
Meeting any other eligibility criteria required by Angi
Keep in mind licensing is different from certifications. A license is a legal requirement to operate a business, while certifications are voluntary.
The average cost of HVAC repairs is around $350. However, that price can be as low as $100 or as high as $2,000 or more, depending on the repair. For example, replacing a capacitor is a relatively inexpensive repair, ranging from $100 to $500. However, a compressor repair is a more expensive repair, ranging from $750 to $2,000.
