In business since 2005, you can rely on us to provide you with comprehensive heating and cooling services. Our locally and family-owned and operated business has over 25 years of experience in the industry.

"Installed new AC and heater unit in April 2023. Had used Garrett prior as I found them reasonably priced. After the install, numerous safety/code violations were found when the unit was inspected. Among them were not adding a safety drip pan under the furnace, not installing a coil condensate drain correctly, running a flexible gas line into the furnace cabinet (a code violation), not terminating the electric correctly (a code violation), leaving exposed wires on the AC unit outside. The new owner claims it's not his responsibility to fix these issues. I'd steer away and go with someone that wants to back up their work (sorry, it's your work if you buy the company). Update as of 01/15/2025 Response to review and company response Jan 2025. Company DID NOT come out or even reach out to me regarding this. Tape and duct work repairs? When did you come to my house? Shows how dishonest this company is. Stay clear. Only excuses from this company (for example. we bought our business in 2024, not our problem!)"

Family owned and operated company since 1954. Quality workmanship is one of our best qualities. Excellent customer service. With over 50 years of experience in the HVAC industry, we are confident we will meet and exceed your expectations. Our quality and attention to detail are unrivaled by the competition. We have served the residents of St. Louis with three generations of Vitts, and are raising the fourth. Our longevity is a testimony to our service and clients' trust. We have an excellent rating with the BBB and are N.A.T.E. Certified technicians. One major difference and benefit of our company is custom duct fittings. Custom fittings give your unit a longer, more reliable shelf life and a professional looking installation. Just ask to see our before and after pictures and you'll see the Vitt difference! Also, NONE of our employees are paid on commission, and do not get bonuses based on sales. What does that mean? That guarantees that we will not try selling you something you do not need. Only if your system is non-repairable, or at your request will we suggest purchasing a new system. We will not have a "salesman" show up at your door whose main objective is to sell you something. We are there to make you happy and comfortable, that's it. NO SUBS. CHARGES BY THE HOUR. NO TRAVEL CHARGES. ADDITIONAL CHARGE FOR AFTER- HOURS SERVICE MAY APPLY

"I'd give zero stars if I could. Made an appt for 12:00-4:00 with me getting a call from the tech Coll Mcminn around 3:47 saying he was on his way and will be 35 minutes. He said that before he comes out it would be $125 just to come out and then another $275 to diagnose the leak in my system. So $400 just to find the problem. As we continued talking I got the feeling like he was just done for the day and was trying to talk me in to getting a quote for a new system so he wouldn't have to come out. I told him the system is 15 years old which isn't that old but he said it was probably in the coils which would require replacing half the system anyway. I only called them because they moved my AC line a few years back and was thinking it possible that they didn't do that properly to begin with which could be the source of the leak. The PVC work that they did was faulty and they had to come back to fix that. Not a great company if you ask me."

"Anytime Heating and cooling was awesome. I called to see if they could come out to see what was going on with our furnace. It was the coldest day of the year! Our home is over a 100 years old and the furnace was once a coal furnace but converted into gas. It needed a part replaced. No other HVAC company had any experience working on our type of unit, but Anytime knew exactly what to do! We are so grateful for them and will continue using them as long as we own our home. I would definitely recommend them for your HVAC needs!"

Tiger Plumbing, Heating, Air Conditioning, & Electrical Services takes pride in being your preferred local plumbers, electricians, and HVAC technicians! In fact, more homeowners in the St. Louis Metro East & Central Illinois communities we serve, say they would call us again before any other plumbing, electrical, heating, or air conditioning service!

"My technician Keith was great. Friendly and super informative. Also too a quick look at the entire drainage system and gave my an idea of where problems will pop up the future without preventative measures (my home was built in the 50s and while the previous owners took really good care of the house nothing has been gutted and replaced yet)."

Paint on the closet floor. I can see the tape on Ceiling through the paint. I had to pay to have them dispose of the removed drywall.

Window a/c unit installations FAQs

Running a window air conditioner to cool a small room often costs less than $4 per day, making it cheaper than central air for single-room cooling. However, central air might be more efficient if you're using multiple window units or need to cool a space larger than 1,000 square feet. Choosing the right size AC is crucial—a unit that's too big or small can waste energy and increase costs.

Window AC units can use a significant amount of energy. These units use about 12 to 17 kilowatt-hours per day, significantly more than a refrigerator's one to 1.5 kilowatt-hours per day. To keep your energy costs down, run your window AC only when necessary, keep doors closed to contain the cool air, regularly clean filters and coils, and seal any gaps around the unit to prevent cold air from escaping.

Inexpensive air conditioner units are often not worth it. Low-cost products from popular brands like General Electric, LG, Whirlpool, or Frigidaire may be a reasonable investment. However, putting a small, budget-friendly unit in a large room wastes energy and shortens the life span of the AC since it has to draw more power and work much harder to cool the space. The unit will consume more energy and stress the motor and other internal parts, resulting in early breakdown and costly repairs.

The best deals on window AC units come during the fall when businesses slash prices to clear out old inventory. You can also speak with your local AC installer, who may get you a good deal on a window AC unit since they have access to trade pricing. You can also watch for discontinued products and flash sales in your area.

Window AC repair costs between $110 and $390, with most people paying around $250. Parts cost between $2 and $150, with the rest going toward labor, at around $30 per hour. The occasional one-off repair or a routine AC tuneup cost $75 to $200. Servicing can keep your AC running in good condition for several more years before you need to pay for a replacement unit.

Window AC units last eight to 10 years when installed and maintained correctly. High-quality models last up to 20 years with proper care and routine maintenance. The unit’s longevity depends on its construction quality, regular cleaning, and electrical safety inspections. Keeping the filters and coils clean and addressing minor repairs promptly extends its effective performance and ensures reliable cooling.
