"We got several quotes from local HVAC providers / installers. We felt the most comfortable with the salesman from Extreme One Hour Heating and Air Conditioning and I got the best price from them which also included a 2-year membership in their Comfort Club (Spring and Fall service visits to check and tune-up my system). We were an all electric home until a couple of years ago when we added natural gas. When our 16-year old Trane heat pump developed problems this proved an ideal time to switch over to a gas furnace and air conditioner. We stayed with Trane as we were happy with our Trane heat pump. Because we have some space constraints and limitations for our new system, Extreme sent out their system designer the day before the installation to develop a creative solution that met our requirements and efficiently maximized the space with which they had to work with minimum impacts to us. The day of the install they arrived on time, were friendly but very professional and treated our home as if it was their own. They also took the time to answer my questions while the worked. Since it was bitter cold that day, they needed to be in and out all day, and we were without a heating system most of the day, they brought a heavy duty space heater to keep us from freezing until they were done. At completion, showed us how to use the new system including the new programmable thermostat, changing filters, etc. and they cleaned up everything and left our home better than they found it. They then submitted all of our rebate paperwork to Vectren and DP&L for us. We were very impressed with the whole process of buying and installing a complete new HVAC system. I highly recommend Extreme One Hour Heating and Air Conditioning for and HVAC installation work!"

"Hauserâ s sales manager and the field tech were both Very polite, knowledgeable and clearly communicated in as much technical detail as I wanted the repairs they recommended and why. Our previous HVAC service provider had diagnosed loss of AC cooling as a compressor failure and had quoted compressor replacement at over $3500 or even recommended replacing the matched AC & Evap Coil unit costing $5-$7K depending on the efficiency chosen. I approached Hauser for a second opinion diagnosis for loss of AC cooling and they diagnosed it as a deteriorating but not failed compressor and had it running in half an hour with a new replacement run capacitor and an add-on electrical gizmo â compressor saverâ at total cost of under $400."

"This company is fantastic. I had a mess in a home we bought to rehab. These folks cleaned the ducts, but saved me $4,000+ dollars on various things they found that were serious issues, that were not related to the ducts. Even found a place where a previous installer for my water heater set me up for a fire. These folks are fantastic. $700 cleaning, $3300 saved!!!!"

"Riley did a great job on a new gas furnace and air conditioner install. I was very impressed from start to finish. He was on time, professional and answered every one of my questions. My system was about 15 years old and I have had to put some money into over the years. I used several other companies during that time and none of them, I mean absolutely none of them, compared to the process I just went through with TrueTemp Heating and Cooling. Everything from the service call, to the consultation process and the installation of my new HVAC equipment was top notch. Can?t recommend this experience enough! Thanks TrueTemp!"

"They were very good with initial response, estimate, and install date. The quality of the install was mediocre; attention to detail, not so much. They did not worry too much about cleanup after the job, several examples of that; I have un-removable black goo on my driveway. There was supposed to be a two week follow-up visit and I was going to address some of my questions and issues then but was scheduled twice and did not occur either time, no call no show the second time. I realize this all occurred during a peak time of year. The unit does work without difficulty and we are happy to have HVAC but I will probably go with another company for service and maintenance.

Heating and Air Conditioning questions, answered by experts

A new HVAC system can increase your home's value by about 5% to 7%, which can translate to an added value of $2,500 to $3,000. The return on investment (ROI) can be around 30%, especially if you upgrade the entire system, including ductwork and insulation. Adding modern features like a smart thermostat can further increase your home’s value by making the heating and cooling systems more efficient and convenient. However, since a new unit can cost $10,000 or more to install, it's important to weigh the upfront cost against the potential increase in home value. For a specific assessment, it's best to consult a local AC installer.

The cost of R32 refrigerant is about the same as the cost of R410A refrigerant, the most widely available type of refrigerant today. However, R32 systems use about 20% less refrigerant than R410A systems, making the refrigerant less expensive overall.

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.

While Freon is mostly odorless, a Freon leak will produce a faint chloroform-like smell. Some people find that Freon's odor has a subtle sweetness to it. Some telltale signs of a Freon leak beyond odor include ice crystals on your evaporator coil, bubbling sounds, and hissing noises.  

No, it’s not normal for AC vents to drip condensation. A sweating AC vent is a sign of something wrong and can lead to issues like air duct rust or mold growth. Your HVAC unit might not be working efficiently because of a dirty filter or clogged ducts. Alternatively, your ductwork might not have adequate insulation, which allows the cool air in the ducts to meet the humid air outside, causing condensation.
