"Water heater went out on a Sunday. Called Monday morning and TMI had an opening. Tom arrived at my home on time, assessed the problem, gave a quote, and then completed the job by replacing the water heater. Tom's work was top notch and completed in a timely manner! I would use TMI again without hesitation!"

"We hired Breathe Easy Air Duct Cleaning to clean out the dryer vent. He was very prompt in contacting me back and got us right on the schedule. He was on time and very pleasant to work with. He did his job quickly and efficiently. We were so pleased that we want him to do some other jobs for us and we already have it on his schedule."

"They fixed my breaker and installed LED lighting, fire detectors in 3 bedrooms in a 6 hour period. Very professional and they cleaned up perfectly afterwards. They could have rushed through but approached me to ask if I wanted dimmer switches and what color. Great work, old school quality customer service."

"Dillon and George were efficient, friendly, fast, fun, and really know what they're doing. Dillon explained the work details, answered our questions, and was upfront with costs, which we felt were reasonable. It was amazing what they cleaned out of our duct work (even an old dead mouse...ick!). We plan to use Preferred Home Improvements again in the future...thanks guys!"

"Excellent service, very fast response to my request for service, picked up laptop, diagnosed issues. Initially thought it was an OS update issue but the hard drive had failed along with other components (including 'CPU). Because other components were involved, a new solid state hard drive was put into a laptop with a working processor - same type CPU as in the failed unit. The laptop was repaired and returned in less than a week. This company picked up and dropped off the laptop (driving from Huntsville, AL (about 60-70 minutes)-- great service in this covid environment. I would recommend this company to my family./friends and will use again."

Heating and Air Conditioning FAQs, answered by experts

Excessive humidity in a room often manifests through visible signs like condensation on windows or walls, a musty or damp odor lingering in the air, peeling wallpaper or paint, and the presence of mold or mildew. Experiencing discomfort due to a consistently clammy or sticky feeling can also indicate high humidity levels.

The size window AC you need depends on the BTU and the size of the room you’re cooling. For a room with 8-foot ceilings, look for about 20 BTU per square foot of the room. For example, a 12-by-12-foot room should have an air conditioner with 2,880 BTU. You can buy something slightly more powerful, but don’t overshoot the BTU for a small room, or you’ll waste energy and have higher bills.

If your home has an existing forced-air heat system, you can add a central air conditioner to it. An HVAC technician can retrofit your forced-air heating system by installing an evaporator coil onto the furnace plenum, the box next to the furnace that draws in air. Once installed, the air conditioning coils use the furnace’s blower to circulate the air.

Yes, AC coil cleaning is definitely worth it. Cleaning your AC coils ensures your AC unit will function efficiently for the long term. Dirty and grimy AC coils make your unit work harder to cool your home, resulting in higher electric bills. Additionally, having your coils professionally cleaned regularly will reduce the possibility of extensive maintenance and repair costs.

Vents may blow air even though the air conditioning system is off because of the pressure difference between indoor and outdoor air or drafts from leaky ducts. Check for leaks or drafts in the ductwork or around windows and doors.
