"I recently had the pleasure of working with Middle Water LLC for spray foam insulation on a client's home and was thoroughly impressed by their professionalism and quality of work. The team consistently showed up on time and adhered strictly to the bid they provided, showcasing their commitment to reliability and integrity. Their dedication and work ethic, particularly the impressive contributions from the hardworking Amish labor, were remarkable. Based on this experience, I have confidently referred Middle Water LLC to another client, who is now planning to use their services as well. The excellent job they did, combined with their punctuality and adherence to the bid, make them a standout choice for insulation services. I am so satisfied with their work that I intend to use them for my own home, which I plan to build in the near future.

No overtime charge. 24/7 Anytime Service. Upfront pricing. Fixed Right Promise. Expert Service Professionals. Financing available, cash, checks, and credit cards accepted.
"Took three times to get it fixed completely. The first repairman had to replace a part and we thought that was all that was needed. The next day or so, water was on the floor again so I contacted Air Serve again. The next problem was a crack in a pan. One of the repairmen, Cliff, was able to keep water from continually dripping on the floor while we had to wait for a new part to come in. It worked quite well. When the part did come in, he did a lot of work to get the new part in. I would have to rate him excellent. The air conditioner is now working fine. Couldnt put an accurate price, because we pay American Home Shield every month and had to pay $75 for the first trip, $86 for the second and I believe $100 for the last trip. Some was not covered by American Home Shield."

"Had them install a new unit last Soring. They took the time to explain all of my options and gave me the best overall value. They also helped me get some rebates due to the green energy of the new unit. They were on time, friendly and left the place as though they had never been here. The unit was amazing this summer and we saved just as they said. We just had sub-zero temperatures, which are rare in Missouri. This Daikin unit was amazing in winter too. I even called them once already with a potential problem. They came out quickly and identified it was not an issue but were again very nice. Best service I have had in more than 39 years of owning a house. Highest recommendation I can give. If you want a great unit and great service from someone you can trust, call Rehagen."

Heating and air conditioning services FAQs
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.
