"If I could, I would give this horrible service provider a 0.0! I scheduled a plumbing appointment on a call, which was confirmed via multiple texts the day prior to the appt. Then had an employee go to the location during the 4 hour window they specified and wait for the plumber. On the day of the appt, 1 hour into the time window someone calls and says, sorry we’re not going to go because we only do residential plumbing. This was a surprise, as it was communicated to them that this was a business when I had set up the appt. So, I decided to speak with a manager. After spending over an hour of being bounced around from one dept to another, asking for a manager, they never connected me to one and their dispatcher had the audacity to say “sorry for your inconvenience, but you’ll just have to find someone else.” WOW! The hoops they make you jump through and the rudeness is not worth the hassle. I would definitely recommend you find a different plumbing pro for your project!"

We're dedicated to providing our clients with the very best in service, installation, and repair for your heating and cooling needs. We are a locally owned and operated company that values honesty and integrity. We specialize in central A/C and cooling systems, as well as heating and furnace systems. We take pride in the quality of our work, and our commitment to outstanding results. We look forward to building long-term relationships with our clients, and guarantee your satisfaction! Visit us @ RJKMECH.com

"Short version: Professionalism, competency, and integrity is what you can expect from RJK. When our AC stopped working, another company came out to investigate and we were quoted an outrageous temporary repair cost and were advised to replace the whole system. We called RJK and they called back almost immediately. Upon arriving, they advised that a whole system replacement would be unnecessary for starters. But before even doing that, they wanted to have their techs double check that the system was truly in need of any replacement. Turns out the fix was straightforward and within 30 minutes the system was repaired at a fraction of the cost of the original contractor's quoted repair cost and definitely cheaper than a whole new system."

"Changing my 5 star review to 2 stars. We have had a HE Boiler as well as a AC/Heat Pump installed by them. Unfortunately we needed service today. I was willing to pay for Emergency service. They said they couldn't make it out for 14 days, because we did not have a service contract. Spent about $25k for the installations. Which apparently means nothing to them What makes matters worse, the Emergency Service we paid through another HVAC provider was only necessary because of an issue they created during the installation. During the installation Speer Air originally ran the line for the residual pump over the copper hot water line. Which over time burned through the residual line, and then cause a hole and leak on the copper pipe."

"I hired 4x4 Home Improvements on several occasions and I've been very happy with their work and versatile skill set. It's the only company I now call for all my home repairs and improvements. Tony replaced or repaired all windows in my house, installed hardwood floor in my rental unit and built a beautiful new porch. He is a great carpenter who can handle various jobs such as plumbing, electrical and much more. Abel is also very capable, installing my outdoor flood lights, and replacing my leaky galvanized pipes in the basement with PVC and copper pipes. When my main sewer line was backed up he used a sewer camera to diagnose the problem. He also replaced my toilets and bathroom hardware fixtures. And finally Henry painted my living and dining room area. This company is reliable, competitively priced, doing an excellent job. I would highly recommend them! "

Heating and Air Conditioning questions, answered by experts

Yes, it’s best to turn off an AC unit that’s blowing hot air to prevent system damage and avoid expensive energy bills. If you let the AC continue running, it will put more strain on the condenser coil and compressor. Plus, if the AC is blowing hot air because of a refrigerant leak, it can also lead to a frozen evaporator coil.

Yes, you can clean your air conditioner filter as a temporary fix for cleaning up dirt, but you’ll eventually need to replace it once the dust starts to accumulate. Use a vacuum with a hose attachment to clean your air filter at least once per year or more often if you have pets.

You can buy R-22 refrigerant for your home air-conditioning system through your local AC repair specialist, who can also refill your R-22 system as needed. You may find that the cost of R-22 has gone up due to shortages as the EPA banned this refrigerant. Ask your pro to inspect your system for any leaks or issues.

You will enjoy greater energy efficiency and save on your annual energy bills, with new, modern HVAC systems using 30% to 50% less energy than older models. Upgrading your HVAC system is also a great way to embrace new technology, such as smart thermostats, lighting, fan speed, and humidity from your phone or tablet.

There are several steps you can take to prevent your AC drain from clogging. This includes cleaning the drain line at least every three months, changing the filter every one to three months, and getting your AC serviced annually. Also, if any problems arise with your AC, hire an HVAC technician to deal with them ASAP.
