"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."

"Extreme Heating and Air Conditioning installed an 18 SEER HVAC system with zone control for me. I am very pleased with the results and performance of the system - far better than the previous system WRT air flow balance. All personnel were very knowledgeable and professional and I highly recommend this company. Thanks to Tristan, Brett, Ryan, Joe, Paul and special thanks to Dave and Tyler for working through some parts failures. I am very pleased."

"Mr. DeSoto did an outstanding job replacing two thru the wall air conditioning units at my home. He found two units that were available and had them installed within 24 hours. He is very customer oriented, well organized, prompt and value oriented. I would recommend him for any heating/cooling work you my need."

"This company is very good. My water heater was beginning to leak and I knew it was time for a replacement and upgrade. Ecoplumbers was able to schedule the day after my initial contact. Ryan offered a quote, explained what he planned to do and installed a new heater within 3 hours. Communication between scheduling services, the service technician (Ryan) and myself was excellent. I am very happy that I used this company"

"Scheduling was a breeze, and  they even came out on a Saturday to do the work.   Bob (the owner) and Tyler showed up on time on the scheduled day.  They first explained the entire process and answered all of our questions.   Bob  even made a couple recommendations regarding the heating system in our home.  They updated us through the entire process, which took about 4 hours.   They moved all of the furniture back after the work was complete and cleaned up any messes.   I felt the price was competitive for the quality of work.  I would highly recommend this company for duct cleaning.

Heating and Air Conditioning FAQs, answered by experts

Water buildup in your HVAC system is a cause for alarm. If water accumulates in your ductwork, it can drastically lower your home's air quality and create safety hazards. These risks include mold growth, damage to your HVAC system, and attracting pests that are seeking water into your ducts. Proper insulation and sealing of ducts can prevent this, and regular inspection and maintenance can address water damage problems before they become too severe.

Yes, mini-split systems are generally less expensive to run than central air conditioners and are significantly more energy-efficient. Because mini-splits do not rely on ductwork, they avoid the energy loss associated with ducted systems, allowing cooled or heated air to reach its destination more efficiently. Additionally, they offer zoned control, meaning you can run units in individual rooms and turn them off in unoccupied areas. This capability can lead to energy savings of about 30% compared to a central air system, resulting in a lower monthly energy bill.

High humidity, bad insulation, warmth from sunlight, and poor circulation are all reasons your home’s hotter inside than out. While this is what you want in the colder months, summer can become unbearable if this is a constant. Try to find the cause, but you need to remember that issues like this require a permanent fix (unless you want to bear down during the summer months).

Evaporator coils in an HVAC system typically last between 10 and 15 years, which is roughly the same lifespan as the entire AC unit. The longevity of the coils can be affected by usage frequency, environmental conditions, and how well they are maintained. Regular maintenance, such as cleaning and inspections, can extend their durability. If the evaporator coil fails in an older air conditioner, it may be more cost-effective to replace the whole unit rather than just the coil.

There are many signs of a bad AC fan motor, including if the fan blades don’t spin when the AC kicks on or if they keep spinning when the AC is off. The AC fan cools down the condenser coil, so a faulty motor can also cause the system to overheat. Unusual noises in the exterior AC unit, including grinding or rattling sounds, may also be a sign that the AC fan motor is worn out.
