"We had purchased a big deal for the service, and it went good. They were not able to honor the coupon just yet, because I had them come and look at a system that already had a problem,  so I am going to end up using that coupon in September or October, and have them look at my heating and AC system. They were overall good."

"Jim is local.  It went great. Jim Ferrell is a professional of the highest caliber. Responded quickly, took care of my problems, and advised me as to better means of protection than I had. He came back a second time to uninstall software that I purchased that did not provide adequate protections and installed free software that would do the job.  He did the work through remote connection, but is available on site if necessary.
For those people needing help on getting red of malware, viruses , etc. on your computer,  Jim is local, better than all thse remote out of state location providers, is a mature, highly trained professional in this area.
If you go to local computer stores you get very young people that can do a basic job, but are no where near the professional level of Jim.
I highly recommend Jim to anyone that needs these type services.

"They worked with us to accomplish what we were looking for. We have 1 ac unit but we wanted 1 thermostat upstairs and 1 down. Then we wanted to split up and down ducting with a valve switch so if upstairs thermostat turned on the valowouls close off down stairs and just cool up. And vise versa. They made it happen and we now have a much more efficient ac system."

Heating and Air Conditioning questions, answered by experts

A dirty AC filter can lower the efficiency of your system, so depending on how dirty it was, you may notice a temperature difference when you clean your filter. You can try other solutions if your AC isn’t blowing as cold as it used to. You can call in a local HVAC tech to make sure everything is running correctly, fix your air seal if it’s a window unit, and clean your coils.

You can protect your air conditioner in the winter by turning off the power at the thermostat and performing routine HVAC maintenance in the spring. Regular maintenance, cleaning, and repair of your AC unit helps protect it and extend its life span. If you have a window AC unit, remove it from the window and store it in a dry place during the winter. Window units cannot withstand freezing temperatures. Keeping them in your window also allows cold air to seep into your home.

You should plan to change your AC unit's filter every one to three months, depending on the manufacturer's recommendations. You should also clean the coils at least once per year, but if you have pets or someone in your household has allergies, you might need to clean them more often. Fortunately, many pros will clean the coils and change the filter for you during an inspection, which you should schedule once or twice per year.

Most experts recommend getting three to five HVAC quotes from licensed, insured, reputable local heating and cooling companies. Getting multiple detailed HVAC quotes (but not too many) lets you compare the equipment, services, and prices of several contractors without being overwhelmed by options. It can also let you see if one contractor’s prices are much higher or lower than the others and give you a chance to ask for clarification. That way, you can weed out any contractors who aren’t providing quality services or materials and find the company that best meets your budget, quality requirements, and long-term goals.

When deciding whether to repair or replace your air conditioner, several factors should be considered. It is generally worth repairing the unit if it's less than 10 years old, the warranty is still active, and you're dealing with a one-off issue. Most central AC units last about 15 years, while window units last 8 to 10 years. If your unit is approaching or has surpassed the 10-year mark and requires frequent or costly repairs (e.g., over $5,000), replacement is often the more sensible long-term investment. For older, inefficient, or out-of-warranty units experiencing multiple problems, replacing it is typically the better choice.
