"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!"

"This is a follow up to my new heat pump installation in 12/2022. Everything is working great. The variable stage heat pump costs more, but it is much better than my old, basic single stage. The air handler was in my office closet, so I spent the day working from home with them working in the same room. Funny and honest techs...I actually enjoyed seeing the entire install while doing my own work. I highly recommend them!"

"Previously I had used Rod Poppe for our HVAC needs, however, when he retired he sold his business to Watkins.  When our air conditioning unit stopped running on Friday evening, I gave Watkins a call.  Since it was fairly late, their answering machine gave an option of leaving an emergency breakdown message or a regular message (which I chose due to the late hour).  On Saturday morning I gave them another call about 8:00 AM and left an emergency message since it was going to be a hot, muggy day and I needed the unit fixed ASAP.  I received a call back from Michael House, the on-call tech very quickly and by 9:30 he was at our house.  After doing a thorough analysis, he found a blown capacitor and low Freon level, but otherwise the 24+ year old unit was in good shape.  Michael was VERY professional, courteous, and thorough.  I would HIGHLY recommend Watkins for any HVAC work."

"I asked for information about a central air conditioning system. Riley told me that because my furnace is 20+ years old, it would make more sense to replace it with a new furnace/air conditioning system. He gave me all the pricing & warranty options. I told him Eco is the first company to give me info, & I would be making a decision within 6 months"

"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."

"I needed an entire new house system with all duct work installed and lines and power. I had window units for air and baseboard for heat. Greg's team was great to work with. Always on time and very professional. Did a great job on the install and I love the system Can't even hear it run. They worked and listened to me on ideas I had on what I wanted to have done, and we worked well together to come to a final solution that worked, as some of the ducts was hard to install. Would use the Blair team anytime. P.S. Great price on the system"

"Our AC wasn’t blowing cold air, Steve came out and diagnosed it as a bad capacitor in no time. Very reasonable cost and quick professional service. Do yourself a favor and go with these guys instead of a major company that you constantly see ads for on TV, you won’t regret it. This company has officially earned all of my future business!!!"

FAQs for air conditioning projects in Dayton, OH

Most professional HVAC technicians require two to three hours to complete an expansion valve replacement. The timeframe depends on your unit's accessibility and whether additional repairs are needed. The process involves recovering refrigerant, removing the old valve, installing the new component, and recharging the system. Scheduling during less busy seasons may result in more convenient appointment times.

Operating your air conditioner with a malfunctioning expansion valve isn't advisable. Continuing to run the system could potentially damage other components, particularly your compressor, which is significantly more expensive to replace. If you notice performance issues like inconsistent cooling or unusual noises, it's best to have your system inspected before continuing regular use.

Expansion valves don't have a standard replacement schedule, as their longevity depends on system usage, maintenance frequency, and environmental factors. Regular professional maintenance helps identify potential valve issues before they cause system failure. Having your HVAC system serviced annually allows technicians to monitor component condition and recommend preventative replacements when necessary.

Refrigerant leaks require prompt professional attention. If your expansion valve is leaking, you'll likely notice reduced cooling performance and possibly hear hissing sounds near the unit. Addressing leaks quickly prevents further system inefficiency and avoids the environmental impact of released refrigerant. Your HVAC technician will need to repair the leak and recharge the system with the proper refrigerant type and amount.

Because many AC issues present similar symptoms, professional diagnosis is recommended. Problems like inadequate cooling, inconsistent temperatures, or strange noises could indicate expansion valve issues, but might also stem from refrigerant leaks, electrical problems, or airflow restrictions. A qualified HVAC technician has the tools and expertise to accurately identify the root cause and recommend appropriate repairs.
