My name is Patsy Cicala Jr., I am the recipient of the Super Service Award for 2016 -2022 from Angie's List. BEST WAY TO GET IN TOUCH IS [email protected], or call 302-245-5606. I retired here 11 years ago in Sussex County after a rewarding career in the field of Environmental Science and General Contracting in upstate New York. When you retire, you should have an exit plan.... I, however, am finding sitting down to read a book or taking a long stroll on the beach will result in either me being placed in a mental institution, or being shot by my wife (she says I am driving her crazy). Therefore, after renovating three homes in the area, I have decided to offer my services as a handyman. My wife says that I can do small repairs including bathrooms, kitchens, and small additions, porches and decks, Check out my Photo Gallery to see if I can fulfill your needs

"I need someone to put up my curtain rods in my bedroom, 2 bedrooms as soon as possible. What will be the cost? I can be reached at 6464364205."

"Mike's team did a great job, installing a new HVAC system, including all equipment, ductwork, insulation, piping, controls, etc. Install in a home without existing duct or central HVAC. System included a combination ducted system for 1st floor and mini split system for 2nd floor (this system, as recommended by Major League, best suited for the existing conditions, accommodating the different zones/heat loads between the 1st & 2nd floor, and the fact that there was limited space for duct work for the 2nd floor ). 1. Work was completed as quoted, and competitively priced 2. Well coordinated, and worked around challenging existing conditions such as plumbing and tight crawl spaces, furnishings, etc. 3.

Emergency services offered

When you need AC heating or plumbing services, look no further than Horizon Services. For nearly 30 years, we’ve been the trusted name in plumbing heating, and air conditioning, offering an unmatched level of service at reasonable rates.

"Less than 5 years ago, I spent in excess of $10,000 to have a new unit installed with a 10 year warranty. I should have seen the red flags from the very beginning. The sales representative told us additional vents would be installed and when the installation crew showed up, that did not happen. Fast forward to the present and I am now on my 4th phone call for an appointment this season, 3 days so far of not being able to work as I waited for a technician to come diagnose the problem. The 3rd. tech came last night and indicated that the work the other tech did was not for the root of the problem. (I was told in front of witnesses that the work needed to be done, was not covered under warranty, would cost me $367 and would fix my issues)In fact, the 3rd tech only made the issue worse by leaving our attic return unscrewed and overfilling our unit with Freon that the 4th tech had to remove from our system. Upon leaving last night I was told that everything was corrected. Today - my home is slowly creeping up in temperature (presently 80 degrees inside, while set to 72). The company keeps trying to sell me a "maintenance plan" and I keep reiterating to EVERY one who pushes it that we have been getting tune ups/cleanings elsewhere and will only use them for warranty issues since we have had NOTHING but problems with them."

Heating and Air Conditioning questions, answered by experts

No, not all HVAC systems have a fresh air intake, but there are many advantages to having one. For example, a fresh air intake can boost the air quality inside your home and help your furnace run more effectively. Plus, it can make your house more energy efficient, possibly saving you money on your utility costs.

There are a few ways to determine if a vent is open or closed. You can inspect the vent and examine the position of the fins. If there are spaces between them, the vent is open. If the fins are flat and touching, the vent is closed. You can also stand under the vent when the system is running to see if you feel air flowing through it.

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).

Most HVAC companies charge a flat service call fee of between $75 and $150, which includes traveling to your home and inspecting your system to find the underlying problem. Keep in mind that these prices only include diagnostics and the actual repairs will usually be billed separately. If you’re calling for routine service, the service call will be included in your inspection and tune-up, with the total sitting around $150. Your prices could be a little higher if you have a very large home with multiple condensers and air handlers, as inspections and servicing take longer.

An AC compressor is one of the most expensive parts to replace on an AC unit if it breaks. You’ll pay up to $2,300 if you need a new one. If your AC is blowing warm air, there doesn’t seem to be a lot of air coming out of the ducts at all, or the unit cycles on and off a lot, you may have a broken compressor. Call a pro to check out your system.
