"I wanted to take a moment to share my recent experience with All City Plumbing. I had been dealing with a recurring issue where the drainage in my home was backing up into my bathtub. In the past, I had dealt with other plumbing companies that provided only temporary fixes while charging excessively. However, my experience with All City Plumbing was different. Junior Maldonado was the technician who resolved the issue, and I am happy to report that, so far, the problem has not returned. I live in Rialto, and I would highly recommend All City Plumbing to others in the area. Special thanks to Junior Maldonado he was not only skilled in his work but also professional and courteous throughout the process. His dedication to providing excellent service truly stood out, and he certainly deserves recognition for his hard work. He deserves a raise! "

RKM Heating and Air Conditioning is your premier company for your heating and air conditioning needs. We take pride in our work and so will you. We are your best choice. Call us today.
"Replacing my heating & air conditioning system was NOT on my short list of favorite ways to spend my money. But after 10 years of unreliable performance from a previously replaced condenser and 20 years of decent performance from the furnace, it was time for a complete system change out. I knew it would be a big job when it was time, and I also knew that proper matching between the condenser, coil and furnace would give me better efficiency. Not to mention the improved technology over the past 10-20 years. From start to finish, my experience with the RKM team was amazing. Knowledgeable, kind, professional and hardworking, I highly recommend RKM for any system replacement job. When our system stopped working, I called RKM and they were at my home within a day. Matthew diagnosed our current system and clearly explained the options to help our decision-making process on the repair vs. replace scenarios. Since we'd already done repairs on the condenser, and the furnace & coil were 20 years old, we decided it was time to stop wasting money on repairs. Getting ready for installation day was a snap with their stellar office staff and automated notifications. On installation day, James & Albert worked hard--even in what must have been 120+ degree conditions in the attic--yes, it was hot! By the end of the day, our home was cooling better than ever! Once the job was done, James clearly explained the new system and ongoing maintenance and reviewed all the work that was done. I was even mailed pictures of their work and diagnostic readings for my records. All in all, a great experience in an otherwise unpleasant situation. Thank you, RKM!"

Heating and air conditioning services FAQs
Yes, most states require HVAC technicians to be certified, and for good reason. Hiring an uncertified HVAC pro could lead to poor quality work, costly future expenses, and potential code violations. A certified HVAC technician tackling your home projects protects you as a homeowner.
As you browse our pro listings, take note of the “Angi Certified” badge. Angi Certified 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
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.
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.
