Running, but not cooling
Warm air can have several causes, including an outdoor unit, refrigerant, or airflow problem. We check the system to find yours.
5.0 Google Rating. Delaware County.
No cooling, warm air, ice on the lines, water on the floor, or a breaker that won’t stay set. We diagnose one system for $129 during regular hours, show you what failed, and give you the repair price before anything gets fixed.

No cooling in a heat wave? Call or text rather than booking online. Same-day depends on current availability, and our team will check the schedule with you.
Katie F. · Google review · May 2026 Quoted word for word. Her full review is further down this page.…he was able to diagnose the issue while he was walking around the side of our house, before he even saw the condenser! …15 mins later we had working AC.
Tell us what changed and we’ll take it from there. We will inspect the equipment and take the readings needed to find the cause.
Warm air can have several causes, including an outdoor unit, refrigerant, or airflow problem. We check the system to find yours.
Turn cooling off and contact us. A frozen coil needs to thaw before we can assess the underlying cause.
A drain, pan, or other condensate problem may be involved. Keep clear of wet electrical equipment and call for service.
Do not repeatedly reset the breaker. Leave the equipment off and have the cause checked.
We check filters, the blower, coils, and ductwork for conditions restricting airflow.
We check operation, airflow, and the conditions affecting how much cooling reaches your home.
We assess how the equipment is operating and whether airflow, controls, or humidity management needs attention.
Tell us when the sound occurs. We inspect the equipment before recommending parts or repairs.
These simple steps can help you stay more comfortable while you wait. If you smell burning, see sparking, or notice a safety concern, keep clear and seek help promptly.
Call us for guidance and allow the coil to thaw. Do not try to chip the ice away or use a heat source on it.
Lowering the setting further will not make a struggling system cool faster. Tell us what temperature the house is reaching.
If you can safely reach the filter, check its condition and replace it with the correct type if needed. Leave equipment panels closed.
Reducing direct sunlight can help limit heat entering the house while the AC is down.
Moving air may help you feel cooler. In dangerous indoor heat, move to an air-conditioned place rather than relying on fans.
Avoid using the oven or other heat-producing appliances while the home is already hot.
A seasonal maintenance visit gives us a chance to inspect performance, drainage, and component condition. Ask us about a single visit or an annual maintenance plan.
Review the diagnostic charges below. We explain repair pricing before you approve work.
Monday through Friday. A real evaluation of one system, actual readings, written findings, and the repair price before any repair work begins. Each additional system on the same visit is $125.
Active Get Comfortable plan members pay $99 per system for diagnostic service calls at any hour, including evenings, weekends, holidays, and overnight. Ask us about enrolling and when member benefits begin.
Includes the trip and the first 30 minutes of diagnostic and repair labor for one system. Evenings, weekends, and daytime holidays are $275. Overnight and late holiday windows are $375.
Regular business hours are Monday through Friday, 8:00 AM to 4:30 PM, and after-hours pricing begins at 5:00 PM. Additional emergency labor is billed in 30-minute increments. Parts, materials, refrigerant, and additional labor are quoted separately and priced before approved work begins. The diagnostic charge is separate and is not credited toward the repair. Payment is due at the time of service.
We check the equipment, take relevant operating readings, and explain the findings. The tests depend on the symptoms and system, and may include the following.
These are some components and conditions we check during an AC visit. Similar symptoms can have different causes, so we test your system before recommending a repair.
We test the capacitor against its rating and check the equipment it supports before recommending replacement.
We inspect the electrical relay that starts the outdoor equipment for wear and operating problems.
Low refrigerant can result from a leak or an incorrect charge. We check the system and explain the repair and charging options.
We inspect drainage and safety switches to find the reason for water backup or a cooling shutdown.
We assess airflow and refrigerant operation after the coil has thawed to identify why it froze.
We check motor operation, electrical readings, and related components before recommending a repair.
We compare the repair cost with the condition of the system, its service history, and suitable replacement options. We explain the choices so you can decide what makes sense for your home.

Erin J. · Google review · August 2026Middletown HVAC is absolutely 5 stars, wish I could give more stars! My AC stopped working on a weekend during a heat wave, I called another large and well known company and they couldn’t come until Tuesday, Middletown came out within an hour of my call, Brian and his wife kept me updated of arrival time, had my AC up and running in less than an hour! They could’ve told me that my AC unit was a gonner when the fan didn’t come back on but Brian knew exactly what to do and did it and my AC was fixed right away and it didn’t cost an arm and a leg! If you need HVAC service please call them, absolutely the best! I am going to get on their maintenance program as well, absolutely fabulous!
Karen G. · Google review · June 2026Heather and Brian (husband and wife) came out to service my two HVAC systems. They were friendly and professional and Brian explained everything very clearly to me. He took his time and was clean and thorough. I love that they are a small family business and that they are honest and trustworthy, unlike other HVAC companies I have used in the past. I would highly recommend them!
Lauren O. · Google review · May 2026Brian came out same day to check our AC. Hottest day of May, he was a life saver, we were sweating our butts off. He replaced our thermostat and was done within 45 mins. Couldn't recommend these guys more! Fair pricing, thorough check and so nice!
Kristen M. · Google review · March 2026Bryan and his wife are such a pleasure. After our last HVAC company (whom we were clients of for 10+ years) left us high and dry when our unit broke last summer, Bryan came to the rescue. From the first call to their office, the initial consult and beyond, they have provided nothing but top notch service.
They are extremely timely, communicative and their prices are reasonable. They’ve won us as clients for life.
Julya N. · Google review · January 2026Brian came right away to my mom’s house and diagnosed the heater issue. Had the part the next day and had my mom’s heater up and running for her. He saved her from another company who told her she needed a whole new system. I would def use them and recommend them to anyone.
Kristin K. · Google review · January 2026I had a great experience with Middletown HVAC!!
My heater stopped working and I gave them a call. Heather answered the phone and was so helpful. Bryan came out to look at it just a few hours later. He was very professional, knowledgeable, and kind.
My husband wasn’t home yet when he identified the problem. Bryan explained the function of part the was broken in a way that was easy for me to grasp.
We will definitely be calling Middletown HVAC again if we ever have any heating or cooling issues!!
